I recently picked up (free) a 1963 10ML60D. It was not running but had good compression so what the **** I only have time to loose. I have rebuilt the carburetor replaced the fuel line and cleaned out the fuel tank. I have it running smoothly and it will run around with out the blower engaged. It runs well without a drop in rpm when I engage the blower but as soon as I put it into gear and release the clutch it stops immediately. I would be grateful for any proposed solutions.

As well as a mixture issue, there is also the possibility of a governor issue. The throttle lever at idle has no tension on the governor spring of any account so engine stalls under light loads. As the throttle lever is opened the governor spring is tensioned and engine speed increases until full throttle is achieved. Usually this is about 3,600 rpm and the engine and exhaust are usually quite loud. So perhaps there may be a problem with throttle lever travel or spring tension so governor is not able to adjust engine speed to engine load. There is usually a second connection on the governor arm that connects to the throttle plate on the carb of the engine. This thin wire connection has a number of possible holes in the carb throttle control. So as the hand throttle is moved from idle to full throttle (engine off) the carb throttle moves to the full throttle stop position. There is usually a screw at the low throttle position to adjust the idle speed. When the engine fires up the carb throttle plate is moved to adjust engine speed. Sometimes it is possible after removing the carb to not get that carb throttle connection in the correct hole and the governor does not function to adjust engine speed to the load effectively. That is when stalling can occur.
