Ok, by adjusting the needles i got the big one running. The other one is a WeedEater brand FeatherLite. It will not prime. When I put gas in it (after checking spark, compression, etc) and started to prime, gas began leaking out of the center of the cap with each press of the primer. I pulled the cap off, looked at it to find the breather in the cap was cocked at an angle. I pressed it flat, gently, and now it isnt getting air to prime. Im assuming this is a case of a faulty breather for the gas cap then? like two or three bucks to fix?
