My bus is stuck!!!!

Hello All,

I am a new skoolie and just bought a 1988 Chevy school bus to convert. On my first time trying to move it i realized the gas pedal is almost to the floor, which seems to keep the bus from accelerating or moving past like 20 mph. Can anyone with a similar bus post a pic of the way its supposed to look down there? Its a 350 v-8, standard tranny. 45 seater. a pic or diagram of the whole assembly from the gas pedal, choke and throttle. On the way to storage we had to park it at a gas station because we were moving waaaay too slow for traffic. So no matter how hard u push the gas the engine revs but doesn't move the bus any faster. Any help would be greatly appreciated. I have no idea what to do!!

If engine rpm responds to gas pedal position, but does not affect physical bus speed, I'd be looking into the clutch/transmission for wear.

I would have to agree that if the engine revs when you press the gas pedal but the bus does not accelerate, your clutch must be slipping. With a manual transmission there should be no slippage when you are not pressing the clutch pedal. I would check the clutch adjustment to ensure that it is releasing properly. You may need to replace the clutch.

Re: My bus is stuck!!!!

I think your description of the problem is a little confusing. It sounds like you are saying that there is not enough travel in the accellerator pedal to give the bus the gas it needs? Are you saying that the bus revs, but not enough to move it fast enough? Maybe the adjustment on your accellerator cable where it connects to the carburator/injection pump linkage has slipped? Perhaps the linkage itself is frozen up/kinked/etc.?

Re: My bus is stuck!!!!

if you smell burnt stuff, thats the clutch. Check the linkage at the carb first though. if its revving like at the red line and its not going thats clutch unfortunately.
