Ok update everyone , motor is back together, has 150lbs compression wooooohoooo! But it's not running very well, running kinda rich, It might also be misfiring ,the lights keep flickering and sometimes quit working ,then come back on. Where should I start checking for loose connections ? Smokes when giving gas . Looks to be gray color smoke.not blue Has a 75 jet in it ,I raised the clip on the needle one notch up where it was at , no difference I turned idle screw in all the way and then tried one full turn out, then one and a half turn out , then two full turns out. No matter what I do it makes no difference unless I turn it all the way in then it whats to stall Sounds like it's running rich. Raising the clip on the needle moves it down which makes it run leaner, so do that.

Now you can dial it in with the needle clip. It's better to be a tiny bit rich than a tiny bit lean. Just so you are on the right page about the fuel/air screw: That screw only affects the amount of fuel that flows through the idle jet circuit when the throttle is closed. It has hardly anything to do with the fuel/air mixture once you open the throttle. The main jet takes over and that's what controls the high speed mixture.

Thanks fox, so how do I figure out where to set the needle at ? by pulling the spark plug and checking how its burning . Making sure its burning a little rich ? Another words should I set clip up till it burns lean then go one notch down to see if it starts burning a little rich ? .if not then go down another notch and so on till I get it where it's burning right?

Yep. Plug color and performance. I like a brown plug that has a black ring at the end of the threads.
