air bubbles in fuel line
 

I just got a used Tmaxx and just got it running, my problem is that the engine keeps stalling sometimes when at full throttle and sometimes when just turning at iddle. I did notice constant little bubbles in the fuel line leading to the carb, they get bigger as the throttle returns to iddle. The fuel line is brand new and the tank cap seems to be sealing fine, could it be the tank? How can I check? What else could it be?
Thanks in advance for any suggestions or advise.

Not positive but lengthening the pulse line fixed this for me.

How about using a fuel filter ?

Being a used car most likely there are a few air leaks around the engine.Air bubbles in the fuel line are usually an indication of an air leak.

Read this article about air leaks and how to fix them.

I've worked late all week and haven't had a chance to work on the truck, I'll definitely have some time tomorrow. Thanks for asking though. I'll be sure to post my results.
