Hi,
I need help with YS 63
Last weekend tried adjust my engine, did brake in couple of weeks ago,
That was running fine, only difference is that I’ve put coil on it.
The engine starts fine, idle was stable, high rpm was 10500 with 14-4, but seems like running to lean – very little smoke on high rpm and no smoke on low rpm,
When tried adjust low needle valve, turn a little with no response from engine, turn on 360 get no response from engine again, I’ve turn low needle valve back and force with no changes on engine work, so that not responding on low needle valve at all.
My question what that may be, and how that can be fixed? That is running fine but I am afraid running that too lean.
Thank you, for any help.
