I have a 94 400L 2X4, i finally got it running but to start it i have to blow into the vent hose(i read that in the forums and it worked). But i have to do this everytime to start it.. I have asjusted the carb and it does no good.. Also it just does not jave any power at all.. then tonight i broke one of the springs that hold on the exhaust pipr to the motor and it ran like a raped ape!!! any Ideas?????????

 

Sounds like you have a plugged muffler.Take the bottom plugs out of it and be sure there is no mud in the outlet holes.

 

I toke it out this evening cause thats what i was thinking too.. Could i rinse it out with some thing??? i didn't see anything in it.. if so what could i use to rinse it out???? thank you

 

Ok i checked the tailpipe and there was nothing in there.. i fixed the broken spring but still i have no power.. any other ideas?????

 

If it runs good with the exhaust loose then take it offf and find the restriction.It has to be in the exhaust system.

 

But i still will not state with the exhaust off thats why i think that it might be in the carb... I was at a job today (bomborder dealer) and asked their Mech what he thought about it and he said something about the engine not being grounded good enough.. But i checked all the wires and the all look fine.. I'm just clueless..

 

Are you talking about the vent for the gas cap or for the carb? Either will have the same effect--starve the motor of fuel. I would give that carb a thorough cleaning--every passage blown out w/ a good carb cleaner (like Honda brand carb cleaner... works mint!) and compressed air.

Just don't get that carb cleaner on anthing rubber-- it tends to make it "grow".

 

Sorry- brain is catching up to me now...

Try turning the air screw in a half-turn (easy stuff first...). I think you may be too lean on the pilot circuit, due to the colder winter temps.

By blowing into the vent, it's having the same effect as a "prime" button on a mower or snowblower-- forcing fuel into the intake tract (suggesting that your lean).

 

i have adjusted it in and out (air screw) and it does nothing.. As for the cold weather it got up to 70 today, so that would have anything to do about it.. Plus, it smells really rich, i didn't check the plug so i don't really know.. i'll take the carb off an give it a good cleaning tomorrow.. thanks for all the advice..
