HI & Welcome,
I've been to Newfoundland several yrs ago. I believe, but can't remember the city name, is the most Eastern part of Canada...correct??

Anyways,have you rebuilt your carbs lately....they may need it esp the little interior filters. If so, then did you set the pop-off correctly, with OEM Miniki parts?

Do you have still have the gray tempo fuel lines? Is so, then change them ASAP to black auto lines. About 20-24 feet of 1/4 inch with Stainless clamps or GOOD zip ties.

I would add an in-line fuel filter too. See this thread by Dr Honda for help on that.

Ok now i was running her and she just cut out it restarted and cut out and again third time would not restart
took it out of the water started it and has been idling fir ten minutes something it wilk not
do in tge water

No rebuild on carb and grey lines still there
is it possible back pressure from exhaust is causing
issue in water

 

[leet66]

Yes newfoundland is most easterly province in canada

When in the warer have to expose exhaust and she starts fine any suggestions?

 

[Dr Honda]

I would start with checking the compression. It should be close to 150 psi, but if it's over 135 it should still run.

Also, as Seadoobudy asked... Do you still have gray "Tempo" fuel hoses?

 

[Seadoobuddy]

When in the water have to expose exhaust and she starts fine any suggestions?

YES, sounds like low compression. Check it as Dr Honda has asked and then report back here.
My guess is it's under 120.

Once it starts with exhaust exposed, then does it keep running OK (smoothness and top end speed) until you shut it off?

 

[leet66]

Yes runs fine going to get a tester to check

 

[Seadoobuddy]

Yes runs fine going to get a tester to check

Maybe battery isn't strong enough to start it under load.....but why would priming it help???????

 

[leet66]

Well one cylinder is at 115 looks like ring job

 

[Seadoobuddy]

Well, that's your problem so far.
What PSI is the other cylinder?

 

[leet66]

140, is it possible she cuts out while running because
of low compression on one cylinder

 

[leet66]

Can the rave valve be adjusted to increase compression?
