Hello. What color is your spark from the spark pug? RED OR BLUE?

is there any way to measure the pick ups?

Here is mine:

i do not have the manual. do you have a link?

Yes. when you move the PV with hand it opens and close. When i remove the exhaust and run the engine i can t see it because the gas hit me in the eyes

Is there any possibility that the engine has a limiter? Mine does not wheelie with 1st or 2nd gear.

I try it with out the end can and does the same. I cant figure out if the main can of the exhaust is full of oil... how i will figure it out?

for 2T engine it has much compression. and it works very smooth... but when it goes around the half RPM something holds it....

All stock

so i have to buy a 150 main jet?

I have the carburetor in my hands and with the first chance i will clean it to be sure that the problem is not from that. I will change the pilot jet. What is the number of the jet that i will buy?

i hope that the problem is that. do you have any idea when you measure with the stroboscope and you raise the rpm the light must go to the left?

what is the position of the needle?

you are the best mike! thank you
