Hi Everyone, May have a chance to buy a non-starting but cranking, with the occasional cough, GT 2550 for $300. 50 inch deck and bagger. Current owner says it was operating as usual then stopped suddenly. I am thinking fuel/carb issue or a safety switch circuit is open??? Would appreciate any experienced input. I haven't seen the tractor yet but may stop to take a look today.
Thanks in advance
Eric

Did you buy it?
