I'm having trouble with mid throttle. I found the timing tape I ordered many moons ago, cleaned the damper, stuck it on. Could barely read the #s behind the pointer. But, I think it was set somewhere around 35 total advance. I took a trip up a side road, adjusted the dizzy by seat of pants, got it better, but still a bit sloppy in part throttle. I'd love to give feedback on where the timing ended up, but the tape flew off! What is s goo source / economic model of timing light with dwell and tach?
