Thanks you. I’ll have to give it a try.

The grommets are easily replaced, hopefully the tabs on the side covers are enact

It's alive!

Exhaust pipes 3 & 4 get hot as hell real quick. 1 & 2 running very cool. Next steps to correct?

Agree. Check the plugs. Coils fire 1&4 and 2&3. Your coils must be working as your getting spark out of each coil. I’d look at fuel supply to carbs 1&2. There is a tee between the carb bodies. It supplies fuel to the carbs from the petcock. Check the petcock to make sure you have flow out of both nipples. When the engine is cold, you can put rags under the carbs and open the bowl drain screws to check for fuel. Also check the vents on the carbs. It the vet is plugged it could restrict fuel. See red arrow on screen shot for vent.

I can take some next time I head out to the shop, but I'm sure you don't want pics of the old ones, as they haven't done anything in 30 years.

Crusty old mechanic from back in the day, "Before you make it run, be very sure it'll stop."

The urge to "just take it fro a quick spin" can be overwhelming when an old bike/new toy runs for the first time. Resist! Been there, done that. It only hurt for a little while.

Brakes aren't sexy like engines running, but unfortunately are necessary.

Good Ridin'

Here's all my spark plugs in order from 1-4. To me, it looks like 3 is too rich, 4 is too lean?

Looks like 1&2 and not firing. 3 is either rich or just sooty because it was just run at idle. 4 is good see the color change on the ground strap it starts to get dark at the bend. That’s what you all of them to look. Still need to figure out why 1&2 are not firing. Also Slmjim brings put a great point. Make sure you service the brakes before it leaves the yard... You can try a quick shot of starting fluid into carb throat 1&2 to see if they will fire.

I got 2 firing for sure now. I *think* I got 1 firing. They were just running too lean. Took the carbs off today. Going to give them another clean tomorrow.
