A fuel pump is way more likely to produce less to no pressure than too much. They regulate by the spring under the diaphragm. Springs get weaker, not stronger.
A common problem, even in service, was the very fine particles of rust from the tank would make it through the course in tank filter, and either unsent the checkvalves in the pump or lodge in the float valve, causing flooding. The solution is to install an online filter, either before the pump or at the carb. The telltale sign this is the problem will be a very fine reddish sediment in the bottom of the float bowl.
If you used an original gasket kit, and the rubber was not happy with the ethanol, the bad results can occur quickly. Overall, they are a simple carb with little that can go wrong aside from those two diaphragm.
The calgary show is a great place to meet the guys from out that way. Only problem is there are way too many buyers vying for my time which cuts into the visitation time.
