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?
