Any ideas why it won't prime and how to fix please. I put my finger over the pipe and pull the cord, no fuel is going in the lines. Checked for blockage, none. And compression feels ok.

try the lean and rich needle until it gets running good. Same thing happened to me I have the lightning gt10 the same exact engine and i had to take it to hobbytown.

My Feedback: (3)

Is the truck new or used and did this problem just start? Try taking the pressure line off the exhaust pipe and blow in the line this should prime it quick. Are you sure you have the lines hooked up correctly?

check your gas cap and make sure its not leaking air.

I was told this is a problem with your Low speed needle being wound in too far (lean)

It was the needle...it was completely closed, go figure...blew in the pressure line not a thing...checked the carb and voila! Thanks guys...and yes it was bought used.

check the gasket on the exaust header, when mine went i couldn't prime it either

how did you needle manage to get completely closed? just careless tuning?

I just got it in the mail and never bothered to check the carb, never thought of it....don't know why it was completely closed. Buddy said he cleaned it before he sent it, maybe he shut the carb?
