Guys I have a 22r. It sat about 4 years. A friend put a fuel cell and external fuel pump on it. The pump runs off a switch in the cab. The only way I can get it started is to prime the carb by spraying some fuel or carb cleaner in the actual pan. It runs fine thereafter. I have tried the $20 carb cleaners, seafoam, etc and driven a good amount of miles. Even if I drive to a show, shut it off, let it set for more then 5 minutes, I still have to prime it to get it to start again. Any thoughts?

 

Sounds like maybe the accelerator pump in the carb is shot.
