Motor Brand and Size

[BigTom]

I have a old Thunderbolt mini muddier and I'm needing a carb for it. Can't find any numbers on the motor. How do I figure how what motor I have? Thanks

Very nice thunderbolt!! Looks stock and O.G. Should be a HS50 is what they came with. I think i see the slanted intake and the tail pipe is correct.
Is that the air cleaner cover on the engine plate in back? Should be able to find a new adjustable carb. P.S. give us more photos please:thumbsup:
