actually i just got done with it. i charged up my glow plug and battery for the roto starter. i put a new plug in tried using that but no it i took it out and checked it and it didn't even light up. so i used an older one and it started right up. i got through half a tank of gas and then it started to rev up and rev down alot and then rev up and then just shut off. i tried to restart it and it didn't work so i put more fuel into the engine and it ran alittle while then the same thing happend and i coulnd't get it back started. maybe it got to hot. i mounted it on a 2x4 then put it on a work bench it actually worked out. just dont know why it was revving up and then shutting down. thats the problem i had in the summer time it would do that as i was running the truck. i think it is better to work on it this way cause when i would try and let the truck idel it would move foward little bit at a time and when it would rev high the truck would go outta control. so i am more confortible doing it like this. do you know why it would be revving up and down then shutting off?
I think you were getting the half tank lean. Search here for the thread ... ofna check valve ... doing the bench running can open new probs , as we can get lost on where you are exactly at as far as tune, etc. As far as I know ( and I may be wrong ) you need a load on the engine. If you are just sitting there on the bench with the motor free wheeling with the clutch bell, it is not the same as running the trk under load, as to check temps and tune. The only motors I ever ran on the bench were plane motors loaded with a prop !!
