RE: Full Throttle Stall - HELP!!
Sounds lean. I have my settings on my sh engine 4 out hsn and 2 3/4 out lsn. To me it is easier to tell a rich engine from a lean engine because I do not have a temp guage.A rich engine has sluggish throttle response and will not reach high speed. It also sounds kind of congested. Slowly lean the hsn 1/4 turn until it has good throttle response. If the engine stalls at full throttle the carb has to be lean. I am new also but I have made it a science to figure these engines out. I am also running mine at the same temperatures you are. I no what the manual says but it really doesnt help a whole lot. You have to find where your engine will run good. Redcat has great videos on tuning learn them because theres going to be other things you need to no. Good luck
