I'm having a hard time finding a good source for these. The only 5mm ones I found are on eBay at like $10 each and that's not happening. I'm also open to other opinions on what to use but I'm really not a fan of Heli Coil.

How about a Time-Sert?

The only issue I have with them is I would need to buy the tool, or am I wrong?

The cheaper the better, but I know you get what you pay for.
I bought a 6 mm tap......next size up 
Key serts work good but they require drilling/tapping a bigger hole than time-serts and on chain saws there just isn't much meat to start with on allot of holes. There was a thread a few months back that went into pretty good detail about all the different repairs
That is what I used to do until I bought the time serts..now I just time sert it and move on.....most stuff that is a viable option but occasionally you just can't go up on bolt sizeI bought a 6 mm tap......next size up

You can get Keenserts for $1.52 ea but you have to buy 100 to get that price. If you only want a few your going to have to shell out the bucks.
Timesert is the way to go. Madsens has the best price I have found on the kits.

It's kinda looking like I might need to go the Time Cert route. They definitely seem to be really good for thread repair. What size is used for spark plugs, 14- 1.25? For some reason that number is in my head. Specifically, it would be for an MS 460

If your dropping $80 for the kit, may as well just buy a new cylinder for not much over that.

Ok, thank you. Could I just buy the inserts if I already have taps and drills or does the installation tool do something other than screw it in?

If I only had one saw and didn't run into these problems fairly often, I would totally agree.

Ah, ok. I had in mind you were repairing one saw.
We have the kits here at the shop for a couple sizes, though they don't get used all that often. Most of the time when a saw comes in with so many other problems it's not cost effective to repair it.
I'd offer to loan, but they aren't mine and it would probably work out that we needed it for a customer's saw 2 days after sending it out.
Several of the saws I sold on here were that case. The customer gave it to us "for parts" but instead I put my time (free to me... sorta) and $$ and fixed it. It wasn't worth it when billing out at $90/hr, but when I fix it for me, I am using it as a "free" training.
The money bought a bunch of firewood for the needy BTW... a big thanks. (sorry a bit off topic)

It doesn't help that I'm also a tool hoarder.

For me the TimeSert kits pay for themselves smaller kits 60 $ Plug kits $ 125 but the plug kits paid off the quickest at $ 40 to repair a cylinder and I've gotten 10 or 11 066/660 cyls with bad plug holes for next to nothing. A plus with TimeSerts is they have BigSert kits for repairing bad Helicoil holes. And yes they use a special tool that cuts a counterbore. Threaddoctor on Ebay carries the kits. On race saws I TimeSert the plug hole and cylinder bolt holes bad or not during the build. Ken
I bought the 5mm time sert kit for the husky 2 series Its been great I have repaired a lot of the top cover holes I bough the kit for $60 maybe Ive also found individual 5mm inserts for about a $1 or so the 5mm insert come a 3 or 4 different lengths which makes it nice when doing different repairs to be able to select a longer thread repair for the top covers for example or a shorter insert for case to coil mount. Its fairly easy to do with cordless drill I would recommend a small tap handle as the tap and instalition tool have a very small sq head to turn them with it can be done with a adjustable wrench but its difficult.
I use Keyserts from Fastenal.

This is the link Brad posted for me a couple months ago. They came the next day I think. These things work very well. Ive used a bunch already. No special tools required. Affordable, buy a bunch cause your going to love them!
