All right guys, I'm having a problem and looking for any secret tips for the mechanical fuel pump.

Engine wouldn't start and I got it down to a fuel issue. Started looking and it wasn't moving any fuel from the tank to the carb. The lever on the fuel pump feels "funny." I can't really describe it, but it doesn't feel like it is moving as far as it should be.

I pulled the pump off, disassembled it and all looks good. I just rebuilt it about this time last year and it has less than 10 hours since then. I reassembled the pump and it felt better in my hand. Reinstalled it then tried to refill the bowl with no luck. I put a vacuum pump on the fuel line and it seems to be allowing the fuel to flow, so I am really thinking it is in the pump. I didn't have a fitting to go straight from the pump to a gas can, but will tomorrow.

Everything looks good, seals are in good shape, springs and caps look good, diaphragm is moving freely. There doesn't seem to be any warping above the bowl either. Are there any secret things that I may not know about?

I'll be back there in the morning to do some more work on it.

Thanks,
Steve
