Re: 29 spark timing #490798 Mar 24th a 02:40 PM

BearsFan315	I set my rough timing engine off per the VCCA specs, then i tweaked it from there. the rough settings got it running. after engine warmed up, i adjusted carburetor to get the idle down then tweaked timing so that the engine would idle smooth with no sputter or back fire (putter or missing) out the exhaust. then revved it up and checked again. drove it and tweaked it, and now it idles smooth, runs strong, and no sputter or miss. i went back with my timing light and it is around 15 at idle warmed up. My old school meter does volt, dwell, and rpm :) works great on these old Chevrolets :) also per the info the idle is around 300 rpm, mine settles around 400-450 true tuning is done by ear and feel and done when the car when it is happy, the numbers are just reference
