I got a vacuum gauge and decided to tune my carb to get the best performance and gas mileage, basically just get it adjusted for my engine since it hasn't really been touched since installing it. So I hooked up the vacuum gauge and adjusted the mixture screws by tightening them until the engine studdered, then backing off until I got max vacuum. I got it to about 16 at idle and 20 at like 2000-4000 or something. After I did all this, I shut the engine off, pluged the hole that the vacuum gauge was in and tried to start it. It wouldn't start. I tried and tried, then let it sit, then tried, let it sit....until it eventually cranked up. Whats wrong? Please help me in tuning my carb. Thanks------------------

Sounds like the float either stuck or the bowl drained all the fuel out on you.------------------

Remove one of your sight plugs and see if there is fuel in the bowl.------------------
