I've got an old half wrap handlebar from a 2-10A. I am restoring the saw and repainting it etc. But the handlebar has this black plastic coating. It's in bad shape. I am not sure if I should leave it as is or not. I think that would look weird on the otherwise almost new looking saw. I probably want to remove the broken black plastic and put something new on there. I could give it a few layers of black powder coating to emulate the black plastic, but I could also do something else. Wanted to hear how others have renewed, or upgraded those handles when they get rotten. Cheers!

Some before and after photos of the saw.

As mentioned...here is my shelf queen McCulloch SP81. Chainsaw ive been working on since earlier this year. The build started with a mislabled engine on ebay for 65 dollars. Seller stated it a 10-10s. However it was actually a PM850. So i took it apart and put in new seals, one new bearing, nos piston. Put on nos bottom brace, nos full wrap handle bar, nos 28" bar and new chain. The muffler was missing so i got a nos 850 miffler duct. I had the front cover. The flywheel is 18 fin and it has a coil off a 600 series saw. The fuel tank is off ebay and has fantastic paint. It was from a pm805. Took the oiler and choke button off a sp81 fuel tank though. Didnt like the colors. The oil tank is also from a pm805. Failed purchase from ebay, worked out in the end though. Most nos parts are from Bob J. The starter cover and clutch cover have been powder coated by a guy i work with. Not a perfect match but pretty darn close. 20210731_181536.jpg 20210731_181549.jpg 20210731_181607.jpg 20210731_181625.jpg 20210731_181638.jpg 20210731_181652.jpg 20210731_181707.jpg 20210731_181718.jpg It runs like a champ!! Great compression and looks awesome to me. Yes the fuel tank is yellow but i really like it. Looks like a SP70. Here are some pictures. Enjoy.

I put the killswitch back together. Silly me, I didn't take a photo before disassembly. Now I am using the IPL and have reassembled according to the picture there. But somehow the switch doesn't 'switch' convincingly. It moves, but there is no clear switch / two polar positions. I wonder what I done wrong? Does this look correct?

I believe that looks correct Simon. When you slide the switch forward, the contact should touch the metal of the handle to ground the coil and kill the ignition. As shown the switch is in the run position. If you install the button backwards it will still work but "Run" and "Stop" will actually be reversed. Forward on the switch is "Stop".

Thanks Mark, yes it worked out I think.

I got the saw pretty much reassembled. It has enough compression to hang from the starter rope so that is a good sign I think. And I can get it to start, but it only starts for 1 sec and then dies again. It must be fuel supply somehow. I think the carb maybe? What to look for? Also, the steel wire piece from the choke to the carb, there is a small eye under the tank area, it keeps falling off that eye/loop when pushing the choke button. Sorry my poor English is failing me here. Anyway, so the entire fuel supply and carb is what I need to go through next I guess.

It's been a fun project so far though, and I like restoring these saws. But its a bit of a shame the yellow powder is slightly off in colour (not deep enough I think). If I could only get the really right yellow (RAL 1023).

I've had the same issues with the choke lever that hooks into the eye/loop coming unhooked too.The choke rods are not easy to bend,but can be done.You'll need a pair of heavy duty needle nose pliers,or a needle nose vise grip to close the hook a little so it'll stay hooked on the loop.Don't crimp it too tightly though.If you happen to crimp it too tightly you can spread it open again with a screwdriver.Since the rod is made of a specially hardened steel,it's possible that it may break.

Perhaps the rubber rod 'snubber' that goes between the throttle and choke rods (thanks for correcting me on the terminology, Ed) is too close to the button end of the rod -- or possibly missing?

Is it weird that I have no memory of writing that??

Maybe I was drunk-posting?
If you are a human male, having no memory of doing something should be a common occurrence. If I had a dollar for every time I've heard a guy say, "Well, I don't recall doing that but apparently I did!" I'd have a few more saws in my collection by now....

That was extracted/quoted from from Yokosukadweller's post. :oops:

I did have a quote of yours from the MM thread in the composition window before responding to this thread, but thought I had deleted it before posting the above. I evidently just deleted the content from your quote and inserted the other. Never even noticed.

Anyway, it was in response to @Yokosukadweller. Glad you caught it!

Lol, those things are so frustrating. They run then they dont, then they do then they dont again. Such a chore takin them apart to tinker on.
I'm up to SIX attempts taking apart and back together...can't get it to stop flooding now, after about minute of running it loads up and won't restart, all the classic signs of flooding, some gas dripping from carb. Doesn't leak when sitting, metering lever adjusted, new carb rebuild and check valve. The dirty MF should run like new...
