Max advance 2.7 w/ webers/solex/9.5 JE's
Anyone running this combo? If so, what did you set max timing to? Single plug, 93 octane fuel.

Thanks Bob! What did you have for idle timing, and was the timing advance progressive or all in at an earlier rpm?

My old 2.7L with "E" cams and 40mm webers making about 190hp, I ran about 35 degs total. I tried vacuum advance and then threw it away. Total advance was all in around 4000rpm. This was confirmed as max advance by J&B racing in Florida.
I have since built a 3.0L, twin plug engine running 28 degs confirmed by J&B racing
