Yes Jimbo, it may be possible to get the jet out but read on !
Tonight has found a major thought, why was only one carb very corroded and not the other two ..........?.q?...
The answer got found a few minutes ago , I drained the two stroke tank down ready for removal , a conservative estimate would be 100mm of pure water , and we are all aware of how it separates in a tank , especially if a total ass ( not me ) uses a mineral based oil .
So had did that happen ??? It's called a split in the rubber / plug / cap thingy , it actually looks like a cup .
Where did the water go ???? Straight into the auto lube pump , that then ends up injected into the tube just before the reeds .
It answered the problem of why it would tick over by die on a whiff of throttle.
It also explain why cylinder two had a wet plug !
The biggest elephant in the room? A hole between the crankcase ? It's fine doing a compression test for most of the time , a full pressure test ( leak down) would be a huge step too far , I have never heard of this engine ( ( Dangar marine in Austrailia ) that has had this issue , if this was the case it would have just overheated and gone bang .
Unfortunately this will of course mean that water may have also gone into the bearings etc, if that's the case it's all over , I was aware that this engine came with this boat as a non runner , possibly spares only ,.
Im not going to give up just yet , im a very stubborn man .
Looking on a positive side I'm learning about engines , strange thing is I'm far happier doing this than watching the telly , the fishing can wait for another few months
