My best was the first time I tried to take one of my mini-macs apart and discovered that a bench vise that swivels is your best friend with those evil little monsters.
I put together a Homelite 7-19 out of two boxes of parts, it was rewarding to fire it up and cut with it.
A couple things come to mind. Working on older Homelites here of course.
- Figuring out the twist needed to get the carb out of a 150. It was an even better feeling to get the twist needed to get it back in!
- The twist needed to seperate a 330 fuel tank from the handle assembly.
- First time I used to fishing line trick (thanks to AS !) to pull a fuel line through the hole.
- Using some thin slices of sheet metal to help slide the anti-vibes free on a 650. Same technique works on all the 450-750 saws. 350/360 anti-vibes aren't a problem since they don't have a metal tip that locks in a dimple on the housing the join.
- Swapping pistons on any 350-750 saw is really easy with a press and a block of oak with a hole in it.

I learned not to apply too much twist to the bearing nut on the flywheel of said 150, the crank is fragile in that area. I guess a lot of WD40 would be better!
That reminds me of one more....
- Threads for the flywheel nut with the overrunning bearing on a 150 are left hand!
and yes, the cranks are fragile where threaded. I've partially broken one when trying to use a puller to remove the flywheel. Still don't have a good technique for removing the flywheels on these saws.

There are many things but doing a pressure test on every re-build is essential now.
