XL With Multiple Problems

[sawnami]

I have a friend that is having a hard time getting an XL going for another friend so I though I'd pick one out of the pile and get it going and give it to him. That's where the challenges began.
It is a very nice low-use appearing saw so I thought it would be an easy fix.
First off it had no fire. I tested the coil on my tester and it fired hot. Found the condenser grounded so I replaced the breaker plate and got fire.
Gassed it and it ran, but was rough running and sprayed fuel out of the carb like a shower head above 3/4 throttle. Took off the carb and looked at the reed valve and it was closed. Took the carb apart and found that someone had put the needle diaphragm gasket on the wrong side so I corrected that and tried it. Still same problem.
I took it apart again and got a donor engine out of the pile to compare with. I pushed the reed on the problem saw with a probe and it fell away from the reed block with little effort compared to the donor saw. I took both reed blocks off both saws and found the drive rivets backed out about 1/8" which made the reed and reed stop very loose on the problem saw. (See the comparison pics).
I put the reed block off of the donor saw on the problem saw and it runs great now.
Might not have taken much for one of those drive rivets to cause a catastrophic event.
So much for an easy fix.🙄

Nice work. Runs like a champ & cuts like a mutha now.

I remember looking at that rivet when I was working on my Super2. Thought for a second about pulling it out to let me clean everything and instantly said, nope, it'll never stay in once I mess with it. Could probably take the loose one out, heat it just enough with a torch push it back in and hold it for a minute, should melt it's way in and glue itself to the plastic again.

Thanks!
Loctite 290 green wicking thread locker would do the job if you didn't have spare part.

It it just the light, or in top pic/left, is the plastic reed block cracked?

Definitely a runner now. Sure is nice when one has parts, or a parts saw on hand to do a repair.

It's just the light.
