Most people don't realize that the cans have different amounts of advance and vacuum levels needed to pull it in. For instance if the can pulls in 10* at 12"s of vacuum and your throttle is at 12"s then the extra timing won't fall out. Another thing to check is that the fuel line is not touching the radiator hose. Putting 200 degree water in direct contact with the fuel line will heat the fuel up fast.
I finally had a chance to start tinkering and noticed that the fuel line lays right on the heater hose, could that be causing the fuel to heat up?
