Should I buy new with a core charg? Or any suggested updraft overhaul shops for my Carb? I think it's time to send it in, and I'd
just as soon do a purchase with a core exchange.

I've never had to do one, it's an HA-6 updraft - anyone know the exact part# replacement I need?
Not sure as it appears theres a number of HA-6 submodels.

Suggestions? Prices? Experiences?

HA6? H means horizontal and since you have an M5 with a C1F it’s horizontal.

Anyway, Mikes Fuel Metering in Tulsa does good work: (918)838-6217.

I misspoke you're of course correct.

I thought I could look on the TCDS to find the exact approved carbs for the C1F engine?
I can't find it - I wanted to find the exact model #'s of the approved carbs for that engine
but not sure where to find this data.

Any suggestions?
