Hi All,
I am trying to tune the timing and carb on my 440.
With the vacuum advance disconnected and plugged, I can get things to where I am happy with them (vacuum, timing, idle speed), but as soon as I plug in the vacuum advance, the idle speed shoots up like 500 rpm, and I can't get it back below a 1,000 or 1,100 rpm even with the idle speed screw backed all the way out.
I know I want to run the vacuum advance, but I feel like something isn't right, maybe with the vacuum advance canister?
I am going to do a little more research, but any advice in the meantime is appreciated.
Thanks.
Greg
