You may get a better response by turning your caps lock off and using some punctuation. The way you have it makes me dizzy.

If the engine slows when the primer solenoid is activated, the engine is not running lean. That engine originally came with a VRO pump. Since you indicate you have two fuel pumps, it sounds like you have replaced the VRO with a pair of the older type pumps. The older dual pumps are not considered rebuildable by the factory. They don't offer rebuild kits for them. There is probably a reason why they don't offer rebuild kits for them. Have you checked for a fuel restriction, such as the anti-siphon valve? What's the compression?

The factory pump diaphragm kits are for the V4 models only, up through 1983. The anti-siphon valve is the hose barb that screws into the topside of the fuel tank fitting. There is a ball and spring inside which can malfunction (cause a restriction) af any debris gets sucked up into the mechanism.

You'll need to go here and do a spark test and a compression test:
