As for the noise in the engine, could be alot of things. If your plug is very oily, then it's probably fouled. That would make it difficult to start & possibly run rough. Pretty common with 2 strokes. Sounds like your mixture on your fuel has too much oil in it when you mix it. Make sure you're mixing your fuel properly then I would check on rebuilding and adjusting your carb if your fuel mix is right. Hope this helps

1993 7 suburban doesn't start wants to but it doesn't start all the way and it makes a funny noise


Hard to say anything about the 'funny noise'.

The engine needs fuel, air, and spark to start and run. If any of these are lacking then it won't.

I would first remove a spark plug from each side of the engine to see what MAY be going on. If the spark plugs are wet with fuel, then I would lean towards it being an ignition problem.

If they are dry, then it could possibly be a fuel problem.

You could also remove the distributor cap to see if there is corrosion on the terminals of the cap and rotor.

I had to rescue a GM vehicle a few years ago that quit running going down the road. The engine acted like it wanted to start but just wouldn't. I did the above suggested checks and it turned out to be the distributor cap and rotor were both corroded to the point of not allowing the spark to get to the spark plug wires. New cap and rotor and it started right up and has been running ever since.

Hope this helps.

My new spark plugs are getting wet, and tail pipe has water coming out of it?


Getting water in the tail pipe is a good sign as the engine will always have moisture when not running. Water on spark plugs is a bad sign as there may be a leak from a cracked cylinder head which is then a major job, the car should be running erratically or will stop.



To check if this is the case take out the oil dipstick and see if the oil is light brown instead of black then you have a problem as mentioned so needs major overall to the engine.

Rm 250 starting issues


This may help you determine the problem.
1. is sprkplug oil fouled? wet? dry? superhot and white electrode?
A sparkplug will always tell you whats going on.
if its too wet then its not burning all the fuel and oil and flooding out.
if its extremely hot and white, then its running lean , and needs more fuel.
also make sure your running 50:1 fuel oil mix.
a hot two stroke is hard to start.
if plug is dry, then its not getting enough fuel.

2. make sure your fuel oil mixture is 50:1.
to much oil is okay but it may smoke alot
way to much oil will oil foul the plug and plug will have oil on it.
to little oil will make the bike run hot and start damaging the bottom end crank bearings as well as your rings , then piston and cylinder walls.
the plug will be whitish and hot.

3. as for the timing , the rotor is resting on a keyway on the crankshaft and will only move out of time if the keyway is sheared.

4. make sure you have good spark when bike wont start.
a coil that is going bad will work cold but may not when it gets warmed up

to sum it up check to make sure you have correct fuel mixture
check you sparkplug to see how its burning
make sure you have good spark

if you have good spark, good fuel, good compression, then it should start within 2 kicks everytime.
i have a blaster 2 stoke 4 wheeler, starts everytimesince i rebuilt it.
i hope this helps you out and you can enjoy the rest of the summer with your dirtbike.
best regards

My snapper hi-vac niwer us hard to start. I can't pull hard enough to get it to start. It uses straight gas, not mixed with oil.


If you are having problems starting your mower you shouldcheck 3 things, air, fuel and spark.

Fuel: check to make sure you are full of good quality fuel, try to start theengine several times then take out the spark plug and it should look wet. If its not wet then you aren't getting fuel into the engine.

Air: remove and clean the air filter with clean gasoline if its made offoam. If its made of paper then you should buy a new one from a localauto parts or hardware store.

Spark: disconnect the spark plug wire from the spark plug and hold thewire close to the engine block. Try to start the engine and watch for aspark to jump between the end of the wire and the engine block. If itdoesn't then either the wire is bad or the ignition coil is bad.

Brand new Honda Generator 2000i will not start. uhhg


Hi and welcome to FixYa I am Kelly.

Things that must be verified.

1. Fuel selector: ON
2. Start run sw: ON
3. Oil Level : Full
4. Choke selector FULL ON for no more than 2 pulls initially The half choke then off
5. Spark at the Spark Plug YES? NO?
a. No spark suspect low oil level sensor is grounding the ignition either due to low oil level or it just is not working properly.

After doing all of the above...

Spark Plug WET or DRY? Dry and still won't start check fuel supply. If you use the choke with the start run switch in the off position the spark plug should get WET. Spark plug does not get wet... with choke on and ignition off. Fuel supply problem.

At this point I suspect either the Oil Level is incorrect or... that the FUEL SELECTOR is OFF.

If you need more help just respond here and we can press on.

Thanks for choosing FixYa

Loud knocking oil in the spark plugs


Do a wet/dry compression test and determine if it's the piston rings or the valve seals.

My 8n (6 volt) will not start. Great spark getting


Spark to plugs is great?.....but if they are black (carbon coated) it may not start.
Crank her over and use that choke for 30 seconds.
Pull the plugs ...are they wet with gas?Smell it....is it water or gas.
They should be wet with something.
Are they dry.........No fuel.

If they are wet with gas and NOT black carbon coated and you are SURE you have spark..........time to tow it to start.
You want to turn the engine fast enough to have the crank throw oil onto the cyl walls. Engines need a oil coated cyl wall to run....to seal the rings.The gas from flooding the engine washes the oil away.Put it back and it should fire up.After the first start...it should be OK.
I've started many a engine that others could not start (flooded or sitting for years) with a little oil in each cyl to seal it.....but towing is the better choice if possible.

Spark plugs for my 2001 nissan altima is always wet with oils and there is no spark, what's the problem?


The spark plugs are probably wet with petrol, rather than oil.

This happens because they are not firing, and the petrol is not being burnt.

This is mostly likely caused by a faulty ignition system.

Does the car start at all? Does it run roughly?

1992 honda accord stop running in middle of driving


When you turn the key to start, the engine cranks over? You must check for spark and fuel, if one is missing, the car won't run. Pull a spark plug, with plug wire connected and plug on a metal surface of the engine, have someone turn the key to start, while you watch for spark at the plug. It is easiest to see spark with car out of direct or bright light. If you have spark, attempt to start several times, pull a spark plug and check for evidence of fuel (wet) on plug. Let me know what you find, we can then continue.
