Thanks, Mark. Knew I could count on you. What's you take on the oil additives? Zddp vs. Marvel Mystery Oil?

FreeRadical said:Hello all,
It's time to put together the carbs today. As usual, I have more questions. I have included some pictures to help explain...
I received my carb refresh parts today including the manifold seal. The previous insulators are made of some kind of perforated metal; however, the new ones look to be made of a completely different material. The Andover parts fiche has two part numbers (067842 and 063458). I'm not sure which one I have, but I assume I just razor-blade the old ones and use the replacements.

My other concern is regarding differences in the LH and RH carb. The LH carb seems to have MUCH better air flow from the two tiny holes in the carb body (pilot mixing chamber?) than the RH when I shoot my compressed air into the gas intake hole (see pic). I have cleaned and prodded the living daylights out of all orifices. I even bought the tiny .016" drill bit to clean out the fixed pilot jet. I've even shot carb cleaner directly into the gas intake hole. I've spent HOURS cleaning this thing. Should I be worried that the two don't act identical?
Again - thanks for all the advice!

This will show how to clean the carb and how to access the pilot jet and then install the blanking screw. A lot of good info here.

It doesn't belong anywhere on a Commando, because as PeterJoe said, it isn't the right part.
Item [1] or [1A] (link) should be either a 30mm or 32mm phenolic heat insulator.

I think there are variations made of some other material nowadays.
