Hello MR Shadel ore any body else i have a YS120FZ that crashed about 2 months ago,the crankshaft was bent so i ordered one,when i got the crankshaft i saw on the package that it was for a YS120NC is it allright?Anyway me and a friend we put the engine together and i started the engine it used to run before it crashed full 2 turns out,but right now i have to close the needle 1 turn for it to run right, is it too lean,the engine is working allright,i`am woried that it is too lean i`am using PRO PATTERN20/20 by morgan fuels and a APC15-10 PROP.I`am in ARUBA so we are at sea level and it is very hot overhere,thanks,

The crankshafts are the same, the part number is YS2310.

If the engine is running OK, don't worry about it. 1 turn open is pretty normal for a 120FZ.

Good Flying,
Dave
