The soft bulb will be either the fuel connectors on the fuel line or the connector on the engine or tank. I'll bet you are using non original connectors on the fuel line which are not always a good fix.

Ah, I'd swapped that out as well. On the Mariner 30 that this engine replaced I had a pump that had a set of gaskets / diaphragm last year.

Guilty as charged w.r.t the connectors.

Don't assume that because a pump had gaskets it's OK. Check it as stated before. It's difficult to get the tension on the gasket the same as the factory and they don't last as long which is why I replace. You won't notice it on a low hours engine but a high hours engine with the old neoprene gaskets, trust me they don't last as long.

It runs better now but water is dribbling out of the drain holes of the tray. Time to take off the head again.

You will have nipped the base gasket when replacing. Unless you had the exhaust water jacket off.

I'm still waiting on the gasket but swapped the float valve to that from the equivalent Mariner carb (the pin is a bit thicker and machined vs a simple thin pin) - it started on the briefest touch of the key (and no water leak this time...)

My theory is that the simple nature of the pin of the float valve made it prone to being pushed to one side as the float touched it and as a result the valve got a bit stuck.

Nearly there...
