Re: evinrude 1985 235 problems need help
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?
