Fun day.. well I had to do some Honey-Does which was digging holes and concreting in some posts for a new yard project - but then I ran out to the garage to strip/rebuild my carb.

It was interesting. I had a rebuild kit and a LOT of jets, so I hoped I'd find some 85 jets in there or something. Or a hole in the power valve. Something obvious. But no.

The primaries were 66, secondaries 70, the normal 6.5 power valve and a plugged PV out the back. Everything sparkly clean and as it should be. Looked at float valves, replaced most parts I had in rebuild kit, but found nothing untoward. The transfer slots were square - everything I looked at was textbook.

With all the new parts in, did it run better? Did it hell! I reset floats, then set mixture using manifold vacuum (went from 16-20).. and the best vacuum, highest idle, and smoothest running is when the screws are fully screwed in. LOL. Given there are brand new parts now in this, someone must have been messing around with this thing.

The nail in the coffin was that I called the guy I bought it from, and he said "yeah, it's always run rich, and the guy I got it from said the same". So I suspect someone set this up for some drag racing WOT somehow.

So I followed NAZ advice and will keep this for parts, or sell it, and I ordered myself a brand new 793-BR-67212 Brawler Street Carburetor 650 CFM which will be here Wednesday.

Which is my birthday, so Happy Birthday to me
