time to retire the 2.5?

[Woof!]

My 2.5 doesn't like to be warm. It runs great for a while but then it stalls out at idle. And it doesn't want to start up for while. This just started happening recently. The motor is 3-4 years old. Is it time for a new one? It also runs real sluggish after a long WOT sprint.

I would reset the needles to factory, seal the carb to the motor and the back plate that helps alot, you could have an air leak, that cause's headaches! Also when done with your r/c, you should put the piston to Bottom Dead Center BDC it helps the piston and sleeve last longer.

 

[Woof!]

how do I go about sealing the carb and backplate?

you seal them with red rtv, you pull the carb and put a thin coat on the inside of where the carb goes and take the backplate off clean real good and use a thin layer and put it back on and let it cure for 24 hrs.
