Hi Guys. Long story short, ended up adding the 6 ports 48cc cylinder and piston from Treats. Change to black springs flush with Synt 10w30.
First run with #72 main 2,17 and 3rd noch from top was lame. It bog down at 1/2 throttle and take of was worst that before.
Not sure why I did some. Stupid reverse thinking. But I changed to #70 and 2nd notch and it's was the worst response ever had hesitations and Four-stroking.
Check and found a little airleak on the intake/cilinder. Temp around 250F.
I'm guessing it is fuel starvation.?
