Someone borrowed my impact driver and hasn't returned it, so that was not an option. The rope trick worked out well though.
Likely that trying to remove the flywheel with a big screwdriver in the fins is how it got broken in the first place. The rope trick works very well. Looks really clean now.
Actually that wasn't what happened. Something broke loose in the flywheel, I think one of the bolts that hold the pawls, and so that piece plus the pawl caused the damage, and those pieces of the flywheel where all over the place. We pulled the flywheel off quite easily using a small prybar and a few gentle bashes with a hammer on the center bolt with the nut covering it to avoid damaging the bolt.
Ouch, i bet that made a awful noise grinding around in there.
i remember as a kid, those boat motors. rentals at a lake we went to often.
Nice! I wondered if I was the only one who cleaned saws with a bright pink toothbrush.....ok sometimes I use one with ponies on it
A McCulloch Gyroplane?!?
Yep exactly - definitely an 'oh shiiit!" moment, like when you're biting into something really delicious and suddenly there's a stone.
Haha its funny you mention that because I just bought 2 kids tooth brushes for port scrubbing and didn't realize that when they're squeezed they light up! And flash!Nice! I wondered if I was the only one who cleaned saws with a bright pink toothbrush.....ok sometimes I use one with ponies on it
You know Kevin,when you screw up I don't feel so bad when I screw up.I hope that makes sense & no disrespect intended.Well I messed up.... I attempted to repair the botched spark plug threads on the Super 250. Somehow I managed to to tap it way crooked!!! With the plug tightened down I could still get a pocket screwdriver under the gasket on one side [emoji2959]
Not all hope is lost, I managed to remove the insert and we have a Time Sert "Big Sert" kit at work that is like triple oversize. I have used it before to repair a badly botched SP81 cylinder that is now on "Scrap Heap". So I ordered the appropriate inserts I hope and when I get them we will give it another go. These are the only pics I have, I didn't bother taking pics once it went to shite.

No offense taken, we all make mistakes. I have repaired this exact scenario a number of times from other people doing the same thing, it was just my turn to mess one up lol.
Saw your post 12/7/20 on why not have a welded pop up . Did you get any further with this . Have with so few options on older saws that are not Husqvarna/ stihl chainsaws . Have a 250 , 10-10 McCulloch and SXL-925 , SXLAO Homelite , with low compression issues .And minimal piston choices .Almost no factory pistons and few after market not of factory quality . have been curios about this for some time , if it can be done .
Yep. Bob Mcculloch dabbled in a little bit of everything
Even superchargers
I've had alot of irons in the fire lately, plus work is consistent 60hrs a week right now. When I do get a chance I'll definitely post it.
