Well I have a new fuel pump , some spark plus , some cable ties , the thing that goes between the engine and fuel pump. I'll 're connect all the fuel.lines and check they are clear. Fit the pump and sparks and give it a go. Since the fuel was only present in the bin after I blew the fuel pump I'm hoping there will be no leaks after I've replaced it. I'll report back once it's done , probably tomorrow. Thanx all

Dismantle carb, probably you have a broken float arm if being plastic and old, bad fuel needle, worn tip, does not shut fuel when float is at it's highest position. You coulkd have also a badly addjusted level float. Get a new carb kit, engine should work much better.

Happy Boating

Small Two Stroke Tip.

When starting from cold. Clean fuel, correct mix. Good fuel line and bulb, check tank, all connections and vent .

Pull out choke and pull six times. If the engine has not fired after six pulls, push in choke and it should go on the seventh. If you don't push the choke in after six attempts, the engine will flood and then it's destination 20 pulls.

Your blown diaphragm gave similar symptoms.

Nice one!

Good feeling when its a problem you have sorted yourself.

Hate to think what a dealer would charge.

That's relative, all brand engines dosen't fire in same amount of pulls. If engine doesn't fire between min 2 or max 4 strong pulls, you have an issue. For instance, my engine fires everytime on second pull at morning cold, that's because I always run my carb's bowl fuel dry at each boating day's end.

Happy Boating
