351W Ford.
Went to break in new engine today,
fired right up, ran great for about 5 minutes, then it idled down and shut off.

Had to crank and crank and crank to restart, then it ran really really rough.

Now it just cranks over and nothing.

1) Getting good spark - using brand new
Proform HEI distributor...Tried moving it around a little bit to see if that helped but no luck.
2) Checked compression in #1 cyl - good.
3) Pumped throttle, saw gas squirting into carb - Holley 4412 500cfm
4) Didn't see any melted ignition wires or anything like that.

**Using hydraulic cam, World 200cc heads, Flat-top pistons, Carter Race fuel pump.


Any ideas where to look?


Thanks!

Does the rotor move in the dist when cranking ?Broken pin in the gear ?

I always set timing immediately at start up. I'd turn crank to tdc and make sure rotor is at #1 or straight across. Then compression on all cyl's. Rocker's too tite? Pumped up and now valve's part open? Either that or dist gear roll pin broke and allowed gear to turn to wrong place, since you still have spark.

May sound simple, but check the plugs to see if their fouled.

I think you identified one of your problems when you used the word "Proform"

Found the trouble...

Checked all cylinders, everything was ok.
Checked the Rockers, they were all at 0,
backed them off to where they were supposed to be, thought that was the problem.

Car still wouldn't run.

Pulled the carb, while looking at the
carb found that there was a piece of
tape on the little tube that runs thru the middle and out the top, I had put it there
while working on the car because it was
very sharp, took the tape off, car runs
great.

I can't believe it ran in the 1st place.

Thanks for all the help, live and learn I guess!

I hope the cam doesn't go flat from all that cranking time.

haha... sounds like something that happened to me a couple years ago. We put the motor in the car... fired it up... ran for a sec then died... couldn't get it started again... sounded like it was really rich.

We scratched our head for about half an hour till i took the filter off to check the carb. turns out my buddy left the paper towles he stuffed in the carb to keep it clean. problem solved.
