Yes,I bought another SEZ on Ebay.The saw looked to be in good shape & it was complete.I got it yesterday & found that someone who was completely void of a brain had tried to put an oversized spark plug in the saw & completely stripped out the plug hole.The oversized plug won't even stay in.It was an AC/Delco CS45T.Those plugs were used on most of the Macs. I contacted the seller to see if he'd take it back & his response was"I sold the saw for parts or repair".If you're reading this Scott,I'm right there with ya buddy.Lol Ed

Sorry to hear Ed! I think I saw that SEZ on ebay as well. Any possibility of a heli-coil?

Yeah fellas,it's called a time sert,but I'd have to buy the installation kit & it's not cheap,well over $100.I can't justify spending that kind of money on a saw that I have no idea what the engine internals are like.The actual inserts are cheaper than dirt. As far as a helicoil goes - if I knew that I wouldn't have any metal chips in the cylinder from drilling it,I'd do that in a heartbeat.I'm open to any & all suggestions. Ed

Strip it for parts or just wait till another one comes up cheap and make a saw out of the 2.

Undee has a good suggestion, there's probably lots of good parts on that saw.
I'd be tempted to tear it down and remove the cylinder to do the heli-coil. It shouldn't take too long (relatively speaking) and all you'd be out parts wise would be the base gasket. Of course, it'd be the same about of labor to just replace the cylinder if you can find a replacement.

I've been looking for one of those for yrs.We called it a plug chase back in the day on the farm.I went to a couple of local auto parts stores,one of them was supposed to specialize in small engines.When I asked them if they had a chase,they had no idea what I was talking about & looked at me like I came from a different planet.Thanks Charles! Ed PS.It was my intention when I bought this saw to be able to make one saw out of this one & the other one I got last month that has a bad bearing.

Back when I worked in the shop, I installed Heli-coils in many a spark plug hole with good results. After the tapping process was done, a little diligence and some compressed air made sure any rogue chips were removed. Never had a problem with one. We used to put them in for $25 and people were tickled to death to pay it.
Of course, now that I think about it more, the kit I had would not have worked on a SEZ without first removing the rear handle/carb chamber. The tool was too long. At that point, it's not much more work to just remove the cylinder:) But who cares about time anyway? We're in this for the results, right? I just spent probably 3-4 hours to clean up an old 925!

The SEZ's are so difficult to work on because everything is so compact.You're the 2nd person to tell me about using a helicoil on the saw within 5 mins.I'll give it some thought.Good deal on the 925! Ed

Ed I went through this a couple months ago. I purchased one from a young guy locally that looked to be in great shape. It had heavy carbon scoring. I ended up buying a replacement engine on ebay for about $50 and it now runs great. I wonder if AutoZone has the time sert tool. They usually let you barrow tools. I hope you left feedback.

I haven't left feedback yet.I'm afraid that if I leave negative feedback for him that he'll do the same to me.I forgot that I bought a used engine on Ebay last yr.for a saw that I burned up the engine on.It was another SEZ.I'm planning on using that engine on a SEZ that I had given to me last month that has a bad bearing.I'd have to buy yet another engine.

I am sure you will get it figured out Ed!
I usually like to leave neutral feedback with things like that- it doesn't hurt but it also doesn't help. I always put myself in the sellers shoes- its possible the seller didn't even know anything was amiss. I usually reserve negative feedback for not shipping an item (or a long delay in doing so), poor communication, or items completely different than described. I considered leaving negative feedback on my XL-98 but ended up leaving neutral feedback.

I probably should've never bought the saw to begin with.I asked the seller twice about the "low compression" & he didn't answer either question.This leads me to believe that he knew damn well what was going on. I took a look at the plug hole today & tried to put a 14 mm.plug in the hole.It's so far stripped out that I can't even begin to put a bigger plug in.I think the cylinder is too far gone to be able to repair it.

That stinks. I hope your not out to much. I would bet he knew what he was selling.

The cost of the saw was $40 + $30 shipping.I've got otyher SEZ's here that I can take their engine & transplant it into this saw,but not right now,way too busy with cutting & splitting.Then gardening coming up next month.Yeah,I emailed him & asked how he could sleep at night knowing that he screwed me over on the saw.His reply was "I had it listed for parts or repair".I should've known something was up when he didn't return any of my inquiries.

Sorry to hear about your issues with the stripped plug. years ago had a small motor that had a stripped spark plug drilled it out ,got a pipe plug big enough ,tapped hole in head for pipe plug.in the pipe plug drilled and tapped hole for spark plug. installed machined plug in head , then installed spark plug in machined pipe plug.the plug I used was brass and that motor ran for years with no issues. good luck

Helicoils and other inserts are available to repair stripped spark plug holes. They all seem to work if the hole is not oversized by wear or drilling.

I got the kit that Classec told me about above.It looks like it's going to work.I just need to find the time to do it.With all the saws I have yet to work on I'll probably have enough work to last pretty much all summer. Ed
