Motor dies

<< < (2/8) > >>

dreracecar:
First test is to remove tank and fill with water with the outlet covered, remove cover and watch flow, should be a constant streem and not surge, if it surges the there is a vent problem.
 Had a similar problem that was pump related, screwed up the endplay an wore the pump cover so bad that it lost pressure at low rpm and coming down after the burnout was not enough fuel to keep it running.
 After the burnout, does the rpm rise before it dies or does it just quit???

we thought one of the problems was the vent,
only had one vent in the back with a  roll over, (last year)
we added one more vent to the tank in the front and removed the roller valve.
both vents are # 6

talked to the driver
not to hard on the brakes after the burn out, but harder on them than the other  2 pass. 3 pass when it died.

drive said, he started to back up and it just died, it may have started to lean out  but not sure.
on the big in it just died after lifting. does not know what the motor did.

other question
once the motor losses prime, does the pump have have to come to a rest before it will prime again ?  to lose the air pocket  it cannot self prime ?

will check the pump,  we had .007 cam end play between the pump and the cam but that was with the old cam.   

sorry this is a bbc injected on non drinkable - safely alc.

with all your help we will find it
thanks steve

We lost end play when we replaced cam,  was a fresh pump and had to turn with wrench, pulled the pump and spun the drive like a top.. that would be my first step based on what happened before

dreracecar:
Didn't mention size of pump
