LOL, that is the case sometimes. It's always a crapshoot buying sight unseen.
Even a blind squirrel finds the ocasional nut.

Yes, I did see the missing brake components. Are they standard 10 series or unique to 82cc macs? Also noticed long carb screws with no opening in airbox. I don't know how you wear through the bottom of the handles. Leave them idling all day while sitting on concrete?
Probably, sliding around in the back of a pickup. Great compression, it runs, looks complete (minus the chain brake), you're off to a good start. Remember its 40+ years old, probably had several owners, and many farmer mods. Super price on an 82cc Mac!!Yes, I did see the missing brake components.

Is this cp125 mac block missing something?
Ozflea the decompressor valve is there its just up and right of the exhaust port. But a block plug is blown out. can the block plugs be replaced?

Make some calls today see if i can get a few plugs.
My fleabay PM800 is giving me fits. As previously reported bad piston, bad cylinder, oiler parts broken, AV mount sheared, etc. I have always thought that ten series cylinders and crankcases are matched machined parts, but I thought I read on AS that they are actually interchangeable. I'm out of cleaner and I've already drilled for the oiler fix so why not just swap the cylinder. At least 6 times on and off pressure testing in a water bath dealing with what I thought was just sealant drying too quickly (it was until I discovered that I was using too much prep spray), I sort it out just to find that there is no way the cylinder will seal to the fleabay crankcase. In my hurry I over-tighten the oiler jig resulting in the wrong angle thus throwing the holes off when I drilled the "new" crankcase. I free handed the fix but I had to sit out the JB Weld cure time to plug the first holes. I put it all together with new seals, pulse line, AV mount, inner bar plate, outer bar plate, 8 pin sprocket, DSP valve and spark plug; the only used parts I put on it were the flywheel, the chain brake/clutch cover, the bar and the chain. As I was cranking it for a test run with the world's shortest recoil rope, I was running through my head what I had actually gotten from my fleabay investment - decent tank, good handle bar, fair AF cover, decent recoil (except the rope), decent flywheel cover, good boot, good fuel line although the bell had been cut off the carb end, good clutch, good muffler, maybe an oiler, bearings and a crankshaft. It ran, accelerated and after adjustment idled well. Once the assembly lube burned off it quit smoking and it ran nice and clean. But then the flywheel loosens, shearing the key and busting the crankshaft. :bang: Someone (who actually knows) please tell me I might be able to simply replace the key, reuse this crankshaft and rely on the taper with a properly tightened flywheel.

PS I can't help but wonder what happen to the original flywheel as the shaft appeared to have spun marks on it and whether the over-tightened replacement flywheel was involved in my diaster. The nut was so tight I had to use a long handled rachet to break it free and I was unable to get the crammed in key out without boogering it so I just left it. I know the loose flywheel was my fault and maybe the result was too. I've sheared keys before but this is my first busted crankshaft.

thanks that'd be great. There is another smaller plug i found on the ipl goes to the oiler hole. Ipl shows a welch plug however i thought i saw someone stake that with a ball lead or BB?I have a factory plug i can give you.

Thanks, Joey. I like your vote. And I would appreciate your advice even if you had voted the other way. Now if you had told me that all crankcases were interchangeable, I might have wanted to choke you late one night this past week; but you didn't. :msp_smile: Ron
Dang Ron, sorry about the trouble. I've had the same thing happen before. I did just what you said, I put a new key in it and reinstalled it. I've had no trouble with it yet. It's been too long to remember which saw it was now.
That's my vote
