I have a JD LT150.When the accelation peddle is pushed down all the way, the mower looses alot of power almost stalling. But when the acceleration peddle is raises about 10mm from full acceleration it works fine. Had a look underneath and at the front and cant find an adjustment for the furl pump. Does anybody have any suggestions.

SOURCE: mower starts then stalls, stalls when throttle is raised

Check your oil filter and oil level. Some have an oil pressure switch that saves the engine but killing spark when oil pressure is too low. That is something near the carb, usually has 2 wires coming from it.

either the steering arm in the bell housing on the right side of the tractor is striped or the colume is broken internaly. the is asuming that all tie rod ends and the bell crank are still atatched.

Carburetor could possibly need cleaning or rebuild, Governor linkage could be dirty and not operating freely, or it could be out of adjustment

Could be ignition module overheating, but then the coke influence doesn't make sense. Once it quits try either a shot of starting fluid in the carb, or tiny bit of gas. If it runs then you know you have a fuel problem. Check to be sure the gas cap is venting and check to be sure you're not getting vapor lock after the motor gets so hot. You could also disconnect fuel line to be fuel pump is pumping. Does it have a kawasaki engine? Beware of some plastic cam gears.
