Anyone know how much vacuum should a 235 register at idle? I have a single 2bbl H-W carb on the engine and it seems that it may have too much vacuum right now. I have not measured it yet (job for tonight) but the vac advance is fully engaged as soon as the engine turns over. Is that normal? Also, how can I adjust things to help reduce the vacuum if necessary? The engine is idling awful rough right now. I have adjusted the points, sealed up the exhaust better, and tuned the carb. I am running out of answers so any help would be appreciated. Thanks!
