Ud_luz, here are some reference points for you.
I posted this in ThumperTalk recently.
I have a 18 EC300 126 hours, runs extremely well. Original piston, power valve has not been adjusted or cleaned.
I am a senior rider & do not ride at full power very often.
Motorex Cross Power 2T 50:1 I get lots of spooge. To me, this means the motor is getting good lubrication. I just wipe it off w/ a paper towel at the end of each ride.
Riding in Colorado & Utah @ elevations 4,600' to 12,000'.
Carb settings: Needle JD Red in 2nd position, Pilot Jet #48, Main Jet 162
Runs a little rich @ higher elevations but fine for me
gez300 from Australia thought my Pilot jet was way too large. Its not.
Hope this helps
