Re: Help -- Old Fashioned engine tuning with vacuum gauge

A couple things I might add.
Whichever fuel pump you chose has too much fuel pressure. Your eddy carb likes no more than 5 psi. You’ll need a return style regulator. Your carb is likely flooding a bit. You’ll need to fix this before you can set your mix screws.
Electric pumps don’t like to be dead headed. That’s why you need a return type reg.
You likely can’t see your timing marks because you’re looking in the wrong spot. Yours should be seen straight down behind the water pump.
There’s also no reason you can’t move your tab/balancer marks to a better location you can see. Just confirm tdc #1 with a piston stop, remark yourbalancer and set up a new timing tab.
