I ordered specific parts for MS MA-4SPA about a year ago and had good luck with MS at this link . But I did have to call them.

needs new gasket , also need to check needle and seat, float level
I think i may have a leak on my carb. Seems to be coming from the throttle body to bowl gasket. I think. Wondering how difficult this is to replace?
I have ordered new gasket for this. Thanks for any help.
