MY tohatsu 9.8 2 stroke outboard is having a problem starting. I had not run it for 3 weeks then when trying it would not run.
1.) i have change spark plugs
2.) Have checked all fuel lines and fuel filters all are fine
3.) i have put a small amount of petrol mix into the engine cylinders to which it started after many pulls however cut out after a minute or so (i have repeated this many times but always cuts out.)
4.) I have completely cleaned the carb which looked to be in mint condition.
could anybody give me so advice on what to do next please?
For me first check is to prove if tank/line are supplying fuel OK.... and if the engine starts OK with a simple fuel supply. Any chance of carefully rigging up a gravity fed container (1lit bottle etc) to the carb and/or filter inlet hose under the hood?

+or just lift the tank up higher than the engine so the fuel just runs you might find a leak with a reverse head
If it starts & runs, albeit briefly, when you introduce fuel to the cylinder(s) then you have a fuel delivery problem or a blockage somewhere in the fuel system.
You'll have to work your way through all pipes & the carb jets until you find it - could be something as simple as a tiny piece of crap blocking the jet(s) or a float chamber jet.
Try disconnecting the downstream pipe from the fuel pump or just before the carb and carefully watch to see if fuel is being pumped as the engine is been turned over.Nik
