could use some info

[b4e2r0t]

i bought my used shee off a guy that bought it from someone else and knows not much about it. i blew it up last year and im just getting around to rebuilding it now due to a new job and so many other things leading up to no ride time, anyways.

 

i have a cool head on it with size 18 domes. once my engine is rebuilt i will check my compression to see exactly what it is for fuel octane. my question is, does anyone have an idea what octane fuel i should be running in it? im geussing at least 100ish with these size domes. i was running 94 and i had predetintation pitting in the old jugs so im leading to believe part of my problem is the fuel. i run klotz as my mix.

 

i also am leading to believe that the timing could be out of wack so i will be playing with that a bit to. any recomendations where i should be at there would help me out also.

 

any input on this would be greatly appreciated

a good timming range is around +4 or +5,though some shee freeks go as high as +7

 

as far as what type of fuel you should run, like you said check your compression after you rebuild-if your any higher than 155 or so, use like a 110 sunco or something like that.

If you go with size 20cc or 21cc domes you can go back to premium gas.
