I have a 63 or 64 7.5 McCulloch with a Marvel-Schebler carb and I want to know if this carb is supposed to have a seat that the inlet needle sits on. I put a new carb kit in it and the kit did not come with a seat and the only carb diagram I have does not show a seat.
Bottom line, the inlet needle is leaking like crazy. 😮
I don’t have the answer to that question, but there may be another cause of the overflow. I have a Glenn manual that might help; I’ll send you the relevant pages if you like.
