What timing setting for RGS?
« on: 27.05. 2014 19:10 »
BSA recommended that the timing be set at 13/32" and SME recommend 5/16" (10/32") for all alloy head engines?

I have a Spitfire cam fitted but only 8.25:1 CR pistons so what is the best setting to use or plum for something in between?

3/8" BTDC was originally quoted by BSA, I now use 5/16" BTDC on my Super Rocket, runs well on std unleaded fuel with lead additive.
1960 Super Rocket, owned since 1966, back on the road 2012 after being laid up for 29yrs.
