Numbers for ST G21/35 DDD head
Hi Gang:
I checked my ST G21/35 with a DDD head and it turned:
8,500 rpm with the same MAS 12x6
11,500 rpm with a MAS 10x6
How do these numbers compare with other engines? Good of bad?
Oh yes, I did have the the engine leaned out and the compression set correctly.
I am now going to check my tach.
Stay well,
Franchi
