Ok, I just picked up a secondhand truggy. I've got 4 other nitro's so have a bit of experience but I just cannot figure out what is going on with the one I just got. Here's whats happening:
Blow down fuel line to prime carb ok, engine fires up and runs for about 20 - 30 seconds then dies. It would appear that the exhaust is not putting enough pressure in to the fuel tank to push the fuel round to the carb.
If I put my finger partially over the exhaust then the engine will tick over great but after i remove my finger it dies again.
I tested for air leaks around the fuel tank, exhaust, manifold, carb etc but can't find any evidence of an air leak.
Compression is ok, not the best, but I've run engines with less.
Any ideas what could be causing this?
Thanks in advance for any help.
