Well-known member
Looking for good parts diagram / parts list for ma-4spa carb # 10-3678-32. It's o320 carb. The diagram I have it is hard to make out the numbers on the diagram and not all the parts shown in diagram are listed in the parts list I have. Missing odds and end pieces n screws... attached is the diagram I have. Looking for something better / more clear and a COMPLETE parts list. Thanks

Greg, thanks a lot exactly what I was after! Is there somewhere that has breakdown on the gaskets included inthe gasket kit 16-676? All I can find is a parts list for the "quick kit". How often does the throttle shaft need changing when you o/h carbs for airboat?
 
there is usually a list of the contents on the kits ...I have found the aircraft kits have a lot of parts in them that airboaters don't necessarily use like safety clips etc that are required by the faa for an aircraft carb....as far as the shafts wearing out usually the bushings wear before the shafts and if there is too much play they are replaced not the shaft but if the shaft and bushings have been left alone too long then the shaft can also wear out of limits....just remember I have all the gaskets , shafts, bushings etc ya need to overhaul that carb...man don't pay those terrible prices for the faa/pma approved parts ya buy from an aircraft parts vendor
 
well i dug this carb out and started looking at it again. i have no idea what i do and dont have, i got this carb & random parts with a basket case motor, keep thinking about putting it together then stop. gmac if i send you the carb and the box of parts that came with it could you tell me whats good bad and do or dont need and put it together for me? it looks like all the parts are the plus some new stuff.
 
that list you posted says the float should be 30-766, the float that is intnhe bag of parts that looks like were removed from the carb is a 30-628 and there is a box with a brand new float with a part number 30-804...
 
hell yes man send it to me and I will take care of it and send it back to ya with the parts that ya don't need or are wrong...….some float numbers have been superseded by new numbers not a big deal ….take about a day...….greg mccloud 4 Henderson rd lake placid fl 33852
 
ok i will put all the parts in box with the float and pack that n the carb and ship it down to you one day this week. -matt
