I'm considering tossing the Husky 235FR brushcutter across the shop. Vacuum test is a big thumbs-up, pressure test holds steady at 5lbs but pisses out of the intake to cylinder joint if you go any higher, new carb, new fuel lines, new primer bulb but the doggone thing won't run. It'll only fire up if I hold the throttle and if I rev it to keep it running it'll just rev slower and slower then die. I've tried setting the screws 1 turn out, I've tried 2 turns, 1.5, 2.5, no change. I'm too tired and not thinking right, what am I missing? Do I need to better seal the intake boot? Any suggestions would be appreciated.
