I bought a Sip Road to my SS 180 and I was wondering about the settings. Sip recommend to change the main jet and optimize the timing. But what settings are correct? I have a 125 main jet, but I didn´t change the timing ´cause I don´t understand enough about it.
Reason why I´am asking is because today I lost all the pressure from the engine. I haven´t open the engine yet but I am guessing it´s hole in the piston, broken piston rings or air leak in the engine somewhere.
What do you think is the reason? Too small main jet, wrong fuel mixture, wrong timing or air leak somewhere? Or all mentioned?
Cheers,
