MF 2520 tractor with 20 hp Intec twin engine model 40C777. Runs good on idle, at full throttle, no load, runs not bad, but a little popping. Turn the deck on to create load, engine is popping and surging.
Any ideas, have checked most normal things, and now is a head scratcher, pull hair out, type of thing.
Carb has been cleaned, valve lash checked , compression checked, coil replaced.
Any thing you can think of, ?
