I started cleaning carburetors last night and made it through two of them. What a mess. They're coated in that nasty green goop that gasoline becomes after its sat way too long. I hate the smell of that stuff BTW.

But two carbs down and two to go:

Trick is apple-cider vinegar and a brass brush :)

Finished the carb cleaning and put them back together. Went with the 17.5 pilot jets so, unfortunately, my prior pilot screw settings are no longer applicable. I set the inner two to 2.5 turns and the outer two to 2.0 turns.

I was able to install those carbs this evening and get the bike running again. It isn't running well but its running. Here she is, right out of the garage, still covered in nastiness. You can hear the throttle hanging and other lumpiness.

To tune it, I need to sync the carbs and then set the[/Video] pilot screws with the A/F gauge. The headers with the O2 bungs are on the Scrambler so I'll have to pull the exhaust off of both bikes and then fit the o2 headers to this bike to tune. Once done, though, I can polish the stainless exhaust and get it back on AND paint the scramblers exhaust, which It desperately needs.

Post bath photos. Enjoy!:

If you're gonna polish these headers, why not just install bungs on them so you them on both for future adjustments?

I don't have the ability to weld stainless. I'd have to find someone who could do it for me. Maybe a a task for my local machine shop??

It's great to see this bike back on the road to recovery. It was almost painful seeing such a good bike so neglected!
