Mower want run when increasing throttle.

[1953pops]

I have a 23 hp exmark. Cranks ok whit throttle on slow but when I increase the throttle it goes dead. Sometimes it pops before going dead. I cleaned the carb. but didn't help. Any ideal?

If it starts fine and will happily idle for along time but dies the instant you increase the speed then either the timing is off ( check the fllywheel key ) or the carb is not flowing sufficient fuel.
Check the solenoid is opening fully and double check that all passageways in the carb are clear.
