Thanks for all the information. Now I have a few other questions on this. I've noticed that my GT will run smooth as can be sometimes, and other times it will run rough and want to pop and backfire at first when I attempt to rev it up, but then it will usually get to a point where it smooths out and revs on up. I doubt that this would be the valves or it would do it all the time. I'm running the origional Solex carb, which I know most people will say that's the first problem, but I have rebuilt the carb and replaced the vacuum lines that looked rotten. Also, if I let it set overnight, I always have to prime the carb with a shot or two of gas to get fuel to pull up to the carb. Once I get it started the first time, it will start all day long until it sits for several hours or overnight. I've checked the lines to the fuel pump and they are not plugged and I pulled the cover off of the fuel pump and cleaned out what little debris there was accumulated in it. I have noticed that the two middle screws that secure the top plate of the carb to the middle body are loose and do not want to tighten up due to the holes being stripped out, so I figured this could be causing a vacuum leak, but I didn't know if this would cause the problems I'm experiencing. Could these two problems be related to each other or are they more than likely two seperate problems? Either way, does anyone have any suggestions about correcting these problems? I haven't removed the fuel pump entirely or completely disassembled it yet. I've heard people talking about the pumps getting gummed up inside after sitting for a while, but once I get fuel to the carb, it seems to run fine. Well, except for the occasional rough running and backfiring.
If any of you out there have any suggestions on this, I'd really like to hear them. Thanks again everyone!
