get a can of starter fluid and spray a short burst into the air should fire up...if it won't stay running or idle your carb is clogged from storage i presume...right? usually storage for more than 3 mos will clog a carb if you did not winterize it...Good luck to you friend...Tim

With apprila Rs 125cc 2 strokes bike. I fill up with 98 octane unleaded and I poured 2 strokes oil Into petrol tank. is it possible can damage the engine?. at the moment I couldnt start the engine.

well you cant damage it by doing that but if you put too much n and didnt shake it well it will settle at the bottom of the fuel tank and fill the carburettor up with oil as oil is heavier than petrol.why are you not using the oil tank and oil pump fitted to the bike ?best thing to do is put a new spark plug in it turn the fuel tap off roci the bike bacwards and firwards to mix the oil and fuel in the tank,and drain the carburettor by undoing the 14mm nut in the centre of the bottom of the carb,then turn the fuel back on and try and start it up.

I have a 1994 ford escort and it's not getting eoungh power I've change the battery, sparks plugs and the alternator don't know what else to do please help

Did you check the timing? If the timing is off there will be a reduction in performance and power will be greatly reduced. If the engine is "pinging" or "knocking" under heavy acceleration, your timing is advanced, and pre ignition is occurring (that's when the spark has ignited the fuel in the combustion chamber prematurely), resulting in a knocking sound. When the piston is compressing the air/fuel mixture within the combustion chamber, the spark plug produces a spark from current it receives from contacts closing in the distributor cap. (Where all the spark plug wires are plugged into) if that spark come BEFORE the piston finishes it up stroke or compression stroke, the piston is then being slowed down from the kinetic energy produced by the exploding fuel. Thats where we loose our power. Idealy, the spark should come AFTER the piston has rotated over the top of its stroke, It has reached its limit in compression and is on its way back down then the spark should ignite the compressed fuel, thus giving the piston an additional "shove" back down to start its "Power" stroke, once its reached the bottom of the power stroke (stroke #2 of 4) it is then carried back up for the "exhaust" stroke pushing the burnt fuel out of the combustion camber and into the exhaust manifold, one it has reached the top of that stroke it begins its journey back down to start stroke number 4, the Intake stroke. Drawing in air/fuel mixture to again be pushed back upward to compress the air/fuel, and repeat the process over and over again. Now that I have thoroughly bored you to tears, Yeah, check the engine timing, if its not the timing it may be a vacuum leak.

Why does my Motor starts but does not go wen I give it throttle

What sort of motor is it? A two stroke or four stroke?
If it is a four stroke it could be a number of reasons why it doesn't go when you give it throttle. It's difficult to help you if you're not providing lots of details. Is the motor by itself or is it a ride-on lawn mower? Usually something like your problem is the result of lack of sump oil and or the timing is incorrect, therefore it can backfire. If it is a two stroke then the carburettor is probably clogged and cannot provide fuel at high revs but just manages to run at low revs.

25 cc carb, new ring and piston, new gaskets, good compression..won't start. when removing plug and looking into cylinder after priming and attempting to start there doesn't appear to have...

Check you have a spark, connect a spare plug and hold it to an earth, crank the engine and watch for a spark. If not check your ignition circuit. If a good strong spark proceed:
Check fuel supply to carburettor - make sure there are no transit plugs that have not been removed. Easiest way is to disconnect the supply hose - no naked lights!!!!
If that\'s OK remove the carburettor float chamber and check that fuel is reaching the carburettor. If the float chamber is dry, check the float valve assembly. There\'s not usually much to small engine carburettors so if the fuels getting to the carb it may be a blocked jet or just very badly adjusted. There is also the possibility that the carb is faulty (yes I know it\'s new but ...!).
If fuel and spark is OK then it could be the spark timing - it should be OK unless you\'ve stripped the engine. On some engine\'s it is possible to set the spark 180 degrees out so that it sparks on the exhaust stroke - just to confuse things some engines spark on both exhaust & compression.
Good Luck!

Good Day Khairul,
Are the Carbs Synchronized To Open And Shut At The Same Time?
If This Is Correct ! Then Do You Need To Pump The Primer To Contine Running?
If Yes Then Replace Fuel Pump DiaPhram
It Coud Still Be An Electrical Fault,
Coil,Trigger Or Stator .
Check To See Condition Of Plugs After Running,
Hope This Helps

Troubleshoot my engine

First remove one or more spark plug and check if they fire during cranking ( Replace therefore the plug in the plug cap and place the metallic side of the plug against the engine-block and crank.)
If NO spark check:
- Deadman knob-is the puller installed?
- Unplug the wiring to remote-control and check spark with manual start. If you have sparks: Problem with contact key/remote control circuit ( check for worn cable, bad RPM counter )
Still no sparks: Check CDI-box
If the plugs are WET: dry them with air, or better replace them!

If you have sparks: Check if fuel come to the carbs. Therefore, unscrew the drain plug ofan upper carburettor at the side of the cowls.
If there is fuel, check after cranking if the plugs are 'wet'. If they're dry: clean the carburettors

If plugs were wet: Empty all the carb cowls ( drain plug ), remove the fuel line ( pince it with pliers if no quick connector ). Crank the engine while carbs are full open throttle for 15 seconds.
Set everything back ( plugs, fuel line, drain plugs, spark plug caps ) and give it a try...

Gas / oil should be in ratio 50 / 1 and use two stroke oil for strimmers or chainsaws.

Firstly check the high-tension lead to the spark plug isn't loose. Remove the spark plug and place the body of the plug against the engine so that it is grounded. Check there is a spark when the engine is cranked. If no spark, there may be a short circuit or crack in the white insulation part of the plug so temporarily try another plug to see if you get a spark. Don't actually use this in the engine unless it's the same time type as it may result in engine damage if it's too long. If this still doesn't work, there may be a problem with the cut off switch, which cuts the engine when the safety handle is released, if this is the case it may be necessary to strip the cowl off the top of the engine to trace the wire and switch.
The fuel lines may have become airlocked.This can happen if the tank is run dry. If the weedeater has a primer bulb, alternatively press it several times and then try to pull start the engine with choke on. Repeat this several times. The primer bulb should feel spongy and fill with fuel.
If you're up to it, you can dismantle the carburettor and clean any dirt from valves.The carburettors on chainsaws, hedge cutters, strimmers etc are very fiddly with delicate diaphragms, valves and springs so you have to be careful to avoid damage or loosing parts.
Ensure air filter is clean. Foam elements can be washed with hot water and detergent and squeezed dry in a cloth. Paper elements can be cleaned with compressed air blown from the inside of the filter but ideally should be replaced.
Check fuel lines aren't kinked or blocked restricting fuel flow.
Ensure fuel filter isn't dirty. This is probably located at the end of the fuel line in the tank.
Check the throttle cable is actuating the throttle plate in the carburettor.
Check whether there is a vent on the tank or on fuel cap. There is usually a valve on this to allow air into tank to replace fuel as it leaves for the carburettor. Ensure this isn't blocked.

I have a yamaha generator and it will not start/electric start or pull also will not start

If it was left unused for a few months with fuel in it the fuel forms a gel in the carburettor and may have blocked jets. Try the solution below:
First to check that the plug is sparking;
  • Remove the spark-plug
  • Push it into the HT lead, the lead that normally is pressed onto the top of the plug, and rest it with the metal part of the plug against the metal of the generator
  • Pull the start cord and see if the plug sparks.
If it does the problem is with the fuel. If it doesn't try replacing the plug.

  • Assuming that the plug sparks alright pour about 5ml, 1 teaspoon, of fuel into the opening where you took the spark-plug out of.
  • Dip the end of the spark-plug in fuel so the spark gap is wet and replace the plug in the generator.
  • Try starting the generator
The fuel you poured into the spark-plug opening should burn causing the generator to start. The procedure may have to be repeated 2 to 3 times.

If there was fuel left for a few months in the generator and it has formed gel in the carburettor this procedure may not work. If this happens the only solution is to have the carburettor stripped down and the jets cleaned by a mechanic.

1977 yz80 wont start. Cleaned carburetor, checked magneto, but cant get to start having problems getting spark, replaced plug.

If you have a spark, but weak. It is possible that your flywheel is demagnetised. Then you'll need a spare.
If sparks are good, then the spark plug should be moisted with fuel after a few ( 10 ) choke kickstarts. If so you'll have a weak compression. Then you have to at least clean out the piston ring grooves ( dismount cilinderhead and cilinder ), or even change the piston rings or overbore the cilinder and place a new oversize piston kit.
If spark plug stays dry when kickstarting, the carburettor is faulty. Clean it out, check also the choke system. Check the air intake between carb and cilinder for air leaks.
