I just got the tractor, I like it but I'm concerned about the amount of blue smoke. I think the PO doctored it a bit for showing cause it did smoke at his house but not so much. It has the Mitsu 2 cyl 25 hp. It doesn't fog up the yard or anything but the blue plume is visible. At what point am I risking complete failure by running it. I assume it's rings. I went thru the possibilities from a troubleshooting chart and found no problems. I didn't do a compression check yet. I'm waiting till I can get a repair manual for specs. The brake rods are broke inside the axel)so I knew I'd have that to deal with. I wasn't looking foward to a rebuild though. Thanks for any advice. BTW I'm not new to MTF but I am new to Satoh.
