Default Week old Stihl BR700X leaf blower failure

I was gifted with a week old seized Stihl BR700X back pack blower. One of the guys workers straight gassed it. I still cant believe how people can use a certain type of machine daily and forget what kind of fuel to use. Even when cans are marked. I tore it down and the piston is beat as it the wrist pin bearing. The cylinder only has some aluminum transfer in a tiny spot I'll remove. Tomorrow I'll order a new piston assy and bearing. The crank seals should still be perfect and I always keep a few tubes of Dirko sealant around to assemble the block. I'm hoping come leaf season this should bring $350.00. I cant fault people for their negligence. I make too much money off it.

How close is it to a BR600? The engine in your picture looks mighty similar.
I have a crank / rod / piston assy from one. Hacksaw owner cut the threaded end of the crank off when he couldn't get the blower wheel off. Crank is trash, but rod and piston are useable. Would have to figure out how to get them off the crank, since it is all pressed together.

Should be the same one. Ive already ordered the piston assy and pin bearing and the total with my discount came to $43.58 with tax so its not bad. I have 6 spare BR600 blocks that had wrist pins seize up from not running the Ultra oil and I was hoping at least one would have a good enough piston to use but they were all too scored and this is too new to cut corners in case I sell it to a regular customer. I just sold a BR600 a customer gave me that broke all four engine mounts but ran great. Never seen that happen. I used his internals in a spare block I had and put it back together and it had zero vibration issues. I could have used those parts on this but oh well lol. I do have usable cranks if you need them though. Thanks for the offer.

I also was given a Stihl blower that had no compression and was pronounced dead by a dealer. No warranty as it was run on crap fuel. This thing looked like it just came out of the box. Not a spec of dirt on it.

The owner ran old premix with ethanol and it stuck the ring. I opened it up and soaked the piston in the ultrasonic then gently pried the ring out. There was some light seizing marks on the piston that I sanded off. There was the slightest scuff on the chrome bore but I'm running it. I ground the limiter caps off the carb needles and it's been running perfectly for two years on 40:1 Klotz.
