None of this is helpful since i wouldn't know what to look for.
The rebuilding of the carb may be one way to look at this issue but I believe there is always more than one way to solve an issue and sometimes you may need all of them or none of them.There is no leaks in the fuel and air lines that I can asses. The fuel system is pumped up from the seperate gas tank that produces pressure in the system and from what I can tell is that the system is or has to much pressure which made me think it might just be that the carb bowl is full and will not except more fuel? Since I am not an engine mechanic (my mechanical expertise lie in the building trades) I am not sure what to do. Hense this is why I am asking you. if the carb rebuild doesn't work where do I go from there? Tune up, coil , spark plugs, points or etc.,?
