It was shown that the vacuum advance was also stuck or inoperative my experience is that the dist was clocked installed off a tooth and its to one side where it cant go anymore and cuts out. I had springs exploed and stuck vacuum advance and still run ok enough where the average Ratsuner might not know the difference. Most of mine where the dist bushing wearing out causing the shaft to wiggle at higher speeds( or causing point bounce when I had points. glad its working get a spare dist where you can trouble shoot faster next time. I always swap a dizzy and if no change I look at the carb(fuel delivery ) in most cases Edited January 22, 2022 by banzai510(hainz) 1 Quote Link to comment

But i got another problem that decided to set me back. 1 step forward 100 steps back. My radiator became a sprinkler today. I posted a form just now. 1 Quote Link to comment

Get a timing light on there and check the timing before you damage the motor. Too much timing can cause piston rings to break and in extreme cases, rod bearing to get squished and fail. 1 Quote Link to comment

datzenmike Posted January 23, 2022 Report Share Posted January 23, 2022 8 degrees with be the static advance. Static advance never changes and is always there When revved up mechanical advance, varies with RPMs, and is added to the static advance. Mechanical advance begins just above idle speed and will max out at around 24 degrees before 3,000 RPMs for a total of 24 +8 = 32 1 1 Quote Link to comment
