What speed? It barely turns over. When I re curved it I used a light spring from (Mr Gasket ) kit? Left the lighter of the two stock springs alone. My timing is set at 8' BTDC total at 36' I don't use the vac can as it causes detonation? Street car but ran a 11.7 1/4 mile on Nostalia Day last year with it with a 323 gear found out when I got home the secondaries were only opening 3/4 of the way. turns out I was missing the small bracket that holds the cable back an inch that I have since fixed.
But I value your opinion and will look into that as well .
