Rebuiling an SBN44 for by WB1 with a 61X single carb. Looking at the diagram provided by Mikuni (attached) I have a "late" SBN44, cause I have O-ring and not gaskets.
Here's my problem: If I install diaphram 5a and try to measure popoff, I get a massive air leak between the pump body assembly and the carb body at anything over 15 PSI. Removing 5a from the carb just using the 6a O-ring to seal it, everything works as expected.
Anybody ever see this?
