RE: Jett .35 RPM range (new)
Hi again.
I returned my .35 Jett and had Jett take a look.
He said he got normal RPMs, but said it looked like sand had been run through the engine. Very worn. This was after about 30 minutes of use.
I used Cool Power 15% and filtered the fuel. So I'm not sure if the fuel was dirty.
Regardless, I got the engine back and ran it twice. I got 19000+ RPM, but richened it to 18000. And my Merlin glow plug burnt out again. The plug end is black with carbon build up.
Here is a pic of my fuel setup. The engine is getting fuel. The needle valve works (leans and richens).
I think I have the same issue as before, but can't figure out why.
