\"Cant find a Leak Down Tester!!! Hey guys me again with the same problem, smoke coming out of my tailpipe from what I can see it looks black, but I noticed what might be an important hint so you guys might be able to help me, that it only smokes when its in idle but if I accelerate a little bit the smoke is gone nothing comes out the tail pipe, but once I let the gas go and it's back on idle it's back to smoking again and like I said it looks more black than anything so do you guys think it could be my carburetor, cause if it was the valves or something else wrong with the engine I think that the smoke wouln't stop when I accelerate right? what do you guys think? and as far as the leak down tester I asked around here and nobody seems to know what the heck I'm talking about went to Autozone, local parts store, Pep Boys and no luck so what do I do guys thanks. keep blazin !!!
