Re: Tuning carb with a Vacuum Gauge
sorry, forgot about the timing.
I started with the 4 degrees from the factory manual. It ran like a bag of $hit. After a long time reading I finally set it up at around 10 or 12 degrees advance. I can't remember where I left it.
It runs good at 60 mph, and at 70. It just stumbles when I accelerate. Lately it is when you go WOT. Half throttle is ok. Also it stalls at idle here and there...
