Part # for Marvel Schebler MA3 / Ma3A?

(1/2) > >>

JoeB:
Does anyone know where to find the part # for a Marvel Schebler MA3a? 
This is for a Franklin 4AC-199E3

Brett Lovett:
From what I can find the appropriate Marvel-Schebler part number for installation on any Franklin 4AC-199 90 H.P. engine is A10-2302.  I found this in a "Service Parts List Model MA-3A as used on Franklin Aircraft Engines" attached to a copy of a Franklin 4AC-199 Operators Handbook & Parts Catalog.

Hi Brett,
I found that a few hours after posting, just got home and see you came up with the same.
Thanks for you feedback on this.
Best Regards,
Joe

Ok, next series of questions.
Do all Marvel carbs have data plates?  This one is a MA-3A but there isn't a flange cast in the body where the data plate is normally located.
I've been told by some that this is not unusual on the older MS carbs, and another opinion that this carb is not legal for use?
If anyone one has a spare MA3A with data plate, I would like to purchase one as right now I am grounded. 
Looking like no Sun-N-Fun this year....

Brett Lovett:
Joe,

The Franklin part number for the carburetor is 10585 (listed in the 4AC-199 Parts Catalog).  I think this part number would have been stamped somewhere on the carb and should provide positive identification of the correct carburetor.  I hope maybe this will help.  I'm unsure on the data plate issue. 

If you haven't already, you might try contacting Marvel-Schebler.  After my experience with a Hartzell representative (the supposed expert on Hartzell wood propellers) claiming it was illegal to fly an airplane (any airplane) with a Hartzell wood propeller (any Hartzell wood propeller) installed, I would advise caution, a sense of humor, and thick skin when making contact with them.  They don't show the A10-2302 as a valid part number, nor do they show any part numbers for pre-war Franklin engines, so they may be very helpful, or they may claim that it is illegal to use any Marvel-Schebler carburetor on any pre-war Franklin engine.
