Might be worth doing the pipe I mentioned in post #3 above while the carb is of for the very small cost involved. See post #8 onwards in this thread...

Mariner 15 2-stroke spitting fuel near carb.

Mine was age hardened and split in extra places as I moved it about.

While checking over the engine be sure to look out for the little fellow below getting caked up and sticking:

Yep I used the paper gasket. The one with the rectangular centre cutout was the nearest but I still had to trim the inner edges a little to get a perfect match to carb/reed flanges. See pics in post #6 of that thread and you can see before trimming the gasket covered a little of the throat edge.

Try setting the idle air mixture one and a half turns out from lightly seated, then if it runs better richen it the width of the screw head untill you are happy. have you the correct spark plugs fitted? in-correct spark plugs can sometimes cause a problem.

If you take your fuel line off the engine and pump till solid how long does it last
I've had a bulb with a hole under the fuel clip where it's rubbed.
Also sometimes fuel lines collapse with age.
A total new line best then it can only be the tank then

That will be it then it should pump up solid up to the connector not sure about merc connectors but mine has a ball bearing with an o-ring seal they some times leak because the bayonet damages the o-ring a bugger to change last time I did one. I would change the whole lot for ease bearbelly

Cheers
