So I finally had a chance to run my 262, I haven't done anything to it yet, it's about 105F over here today with humidity. I cut about 1 acre with no issue, I was really happy with how it ran, then I had some issues.
It started to hesitate even when not under load. It would idle up and down, up and down, under load (I started the blades but was not moving) it would nearly stall, then I would turn the blades off, it would give a puff of black smoke and rev back up. I would cut for a bit and it would stall, it would start right back up, I would cut for a bit and stall, and start right back up. Then it was fine for about 20 mins, then it started cycling up and down once again. It's odd because it was plenty hot long before the problem started.
That first acre I cut was great, I was really impressed with the power, the grass was about 5" long and wet and it mowed it without any problem whatsoever!
Thank you for your advice!
BTW: I will be leaving for vacation soon so I apologize in advance for my late replies.
