A lot of people will frown on this solution but it is quick and easy to test. Spray a shot of starting fluid into the intake, if it pops when you try and start then lack of fuel is your likely cause.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Clean the air filter. Install a new stock NGK spark plug.

Please rate this solution. Thanks!

Hi Dino,
You have sparks and the carbys have fuel in it.......you crank it and it doesn't fire up.....have you tried to use the choke?
After a lot of cranking remove one of the spark plugs and see if its wet with fuel.
I feel probabely the fuel is not entering the combustion chamber.

SOURCE: 1994 ltf3004wd king quad fuel pump

There are three connections to the fuel pump.
Fuel in/out at ends, the pipes should only reach to the correct ends. The IN pipe connects to the end toward front of the bike , OUT toward the back heading to carb.
A small connection on the back for the vacuum pipe from the carb.

This pump only spits the fuel along rather feabley, also check the gause on the fuel tap. When bleeding, remove the fuel pipe from the carb and blow into the tank in order to force the fuel through the pipes until all air is removed.

When coming to a stop engine would chug and then die start up and go it happens intermittenly


Needs some inspection and tuning. Plenty of reasons. Carbie? Spark plugs been done of not? Coils? Points? Because as you describe, it would more likely be getting too much fuel and weaker sparks because RPM gets low, then it wouldn't be able to ignite the fuel and die, but because you got already too much fuel, starting again is easy. So I'd say give it a tune, like check air filter, spark plugs, coils, points....whatever it is.
What''s the systems? Carbie? LPG? Diesel? I have no idea here!

Cannot get my bike to start


Remove rubber connection from carby inlet (between carby and air filter) enough to get a piece of thin card to cover inlet to carby. Turn motor over with throttle half open for a few seconds. Remove card and see if any fuel is on the card. If there is, repeat process (fresh card) without throttle, fuel should still appear. If there is no fuel present, you have a fuel blockage. If engine still not starting with fuel present, you have an electrical problem, check for spark by resting attached plug to engine metal and turning engine over.

I have a yamaha ttr230 and since i have pulled it out of storage this spring it cant make it run right. It starts fine and idles but a soon as any throttle is given it dies out . I have put fresh gas in it...


G'day, sounds a bit like the float valve in the carby might be stuck nearly shut or just some moisture in the carby, a light tap with the handle of a screwdriver on the side of the carby bowl should fix it if it's the needle stuck shut (happens from sitting sometimes), or maybe try loosening the drain screw in the bottom of the carby bowl to drain any water etc out, hope this helps :)

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.
