92 GTX Rotary plate removal

[jeeprunnr]

I just got this ski. It doesn't have the grey lines, but the PTO cylinder oil line is dissintegrating. I want to switch to premix.

The manual says to get to the oil pump you have to remove the carbs. To remove the carbs they say you unbolt the rotary valve cover with them to get out.

I can get only 3 screws out. The 4th which is the lower front one is too close and I can't get a wrench around it. It can't be as difficult as it seems.

How do you get the bolt off or what is the easier way to get the carb off?

(I already took the airbox and the flame arrester cover off)

Thanks.

you can finesse a 13 mm wrench in there. might help to get a 8mm and loosen up that banjo fitting on the one oil line that is ruining your day. then swivel it outboard to get room behind it.

Thanks. I finally got it off with some work.

The small oil line was dissintegrated... I pulled off oil pump and went premix. I left the two large lines connected to the oil tank and will keep oil in it to keep lubed...

I have to now take back out on the water and see if this was the problem for why my PTO cylinder was hot.

If not what are other causes? Could rear carb be too lean? And if so how much and which screw should I increase???

Or could there be sand or oxidation in the engine restricting flow of coolant, and if so how do you clean that out???

Its A Twin Carb And You Can Have The One On The Bad Cyl Stopped Up Or Have A Whole In The Diapham Causeing It To Run Lean.
Also Make Sure To Block Off The Oil Injector Ports So You Don't Suck Other Stuff In The Intake.

Adjustments...?

One cylinder running hotter than the other, is indicative of an improper carb set up (one running lean, the other not). Either by incorrect carb syncronization or mixture screws not set in unison.

Check your syncro on the carbs and make sure your mixture screws are both set exactly the same.

Run the engine WOT for a few minutes, then kill the power. Have a spark plug wrench with you and pull the plugs. At the bottom of this post, is a link to a page that has a spark plug chart, for reading your plugs......take a peak, then tell us what they look like..:cheers:
