Hi everyone! I need help badly! I just got the sirio engine and the ntc3 starter box for it. I'm having trouble starting the engine. The fitting of the piston and the sleeve was so tight I can barely turn it with my hand, which mean that my starter box can't either. I tried to heat it up with a hair dryer, it got up to about 140 degree. But still won't work, my flywheel even got loose. My question is can anyone please show or tell me how to start my engine? I did post on the ntc3 forum but only got one reply. Hopefully I could get more help by making a new thread. Any help is very apperciate, thank in advance.
