I am having an issue with my 2535. It starts and idles fine, but once I go out to cut my fields it starts losing power. If I dont pull in the clutch it will stall out, but eventually with the clutch in it will regain the revs. Yesterday it wouldnt even start so I thought it was a fuel issue. I followed it from the fuel pump forward and it seems like the flow is fine. I cleaned out the fuel filter and bleed the line. It started right up and idled fine, but once again as soon as I went out to cut the grass it started to lose revs and stall out. I have no idea where to look next.
