632 stalling under load

[632stalling]

looking for help with bobcat 632 stalling when trying to move machine, runs and idles fine if just sitting. when control sticks pushed forward machine barely moves forward and engine stalls. if I move controls both forward at the same time I can get machine to move forward slowly, as soon as I release one control engine will stall. any ideas appreciated thanks.

Check your ignition timing, when mine did exactly that the distributor had moved/loosened and the timing was way off. Idled just fine though. Too big a gap on spark plugs will make it act like that also but check the timing.

While you are doing the timing check the point gap also , they will move sometimes too.

Also while you checking the timing make sure the timing advance is working. Could be something as simple as a cracked vacuum hose to the vacuum advance or the centrifugal weights are stuck.
Did you just buy this machine or have you had it for awhile and this is a new problem?
