Hey guys I have a 2159 trophy, it had a 305 in it and I changed it out for a fresh 350 it runs great I rebuilt the carb as well it has propane intake gaskets with the bypass closed because I thought it was heat issues but am thinking it is possibly freezing up
I also changed out the carb for another that was running on a 350 with out issues
The problem is I warm up the motor and head out it runs great for 20-30 min then causing at say 3100 rpm it starts to loose rpm with nothing above the current throttle position
I shut it down for 2-5 min and good to go for another 8-10 min then the same thing
I installed an electric fuel pump thinking it was a fuel delivery problem but no doesn't seem so
Base of the carb is cold but I don't see any frost or anything
The weekend before it did it only once crushing at 3100 so after a 5min shut down I crused at 3400 with out further issues
I know with certain humidity it cases issues
I'm not at sea level but the weather is warm
Any imput would be appreciated
Thanks Tfl
