Pro 785 runs better with seat off to rich ?
Have a 785 that with seat on runs at high speed than slowly dies. Hit the primer with 3 to 4 shots. starts right up and runs great for 30 seconds again dies. With seat off runs fine . Check no exhaust leaks, fuel leaks, new fuel pumps , carbs rebuilt, and new fuel lines. Plug color good. and check pickup tube too rich fuel mixture ? Kind at a lost what to try next

Check the exhaust hoses for internal collapses. It could have a bubble on the inside that smells up somewhere blocking exit flow.

Update , was the stator when cold readings were within spec, when hot readings went off the wall . Thinking with the seat off maybe was getting cooler air over the engine Big thanks to Lugs 785 for helping me out !!
