I have a husqvarna LTH1438, runs fine for 20 minutes or so but then engine rpm pulses then shuts down. I checked fuel cap it isnt clogged and replaced plug and fuel filter. What else could it be?
Check for grass / dirt build up around the head and barrel fins as they block up and the engine over heats as the cooling fan on the flywheel cannot circulate cooling air
