:roll: hay my pit bike starts and runs but after like 10 sec it stols is it the carb or the seals or what please help

Need a little more info to really make a judgement.

When it stops, does it stop suddenly, or does it start missing, get worse, and then stop ?

When you re-start it, does it start easily, full choke -- no choke ?

Does it have fresh gas -- with/without ethanol.?

Are you in a cold climate ?

Could be your gas cap seal or petcock or crud in the carb. It could be a lot of things. Fresh gas and trying to run the bike without a gas cap would be my first set of checks. Then drain the bowl to make sure you are getting gas to the carb. Do you have a voltmeter to check your battery?

Gas and spark are the first things to look for IMHO.

Sounds like you are not getting any gas. Most likely a plugged up jet. Make sure gas is getting to the carb from the tank too.

I had a stuck float on my 125 after it sat for a few weeks. The carb was new too. Only about 3 hours on it.

I'm with Ironfist, I'd try to run the bike without the gas cap and see if that helps. It might just be a plugged up vent in the cap.

Sounds like Another plugged Pilot Jet...................... and or maybe not running an air filter.

The two pitbikes I bought had some incredibly worthless airfilters. They would not have kept marbles out.

Yes you are supposed to be able to see through them... I hope you didn't run a drill bit through the pilot jet, that could ruin the size it's supposed to be. Same with the main jet.

rocketaj · 01-28-2009, 08:45 PM
