Wet Air Screw

For some reason, my air screw is wet. The carb doesn't pee, but there's a lot of spew coming out of the silencer.

Must be the float level, any other suggestions?

Thanks

Check your float level for sure. Being the early model 200 I can't say much on the jetting. But, if your AS is less than 1 turn out, the theory is, you need a bigger pilot jet.

any fool proof procedure for checking float level???

Get yourself a shop manual, tells you how to do everything on your bike.
Mine cuts off at '95, and everything is different for the earlier models, right down to how to set the float level.
Meantime, do a search on the subject, I'm sure it has been discussed here sometime in the past.

I have the manual, it's kind of vague unless you
have the special tool.

Set the float height to the recommended 16mm as shown in measurement #4, and you should be good to go.
My manual shows the "special tool" too, but I just set it by measuring it and all works fine.
The difference between the '95-up and the '94-back, is that the newer version has to have tha carb body angled when you measure the float height, so that it doesn't compress the spring loaded float pin. The older ones can apparently be level upside down to set the height.

Ok, so I pulled the carb and the lower part of the air intake (airbox) had fuel on it, I raised the carb float level approx 1 - 1.5 mm.

That should lower the fuel level ?

Yeah, but if the float level was too high you should have had some fuel overflow. Perhaps the overflow vent is clogged?

Which vent would that be? The carb doesn't "pee".

Something is not right, I went from 1172 to a 1173 needle and 155 to 152 MJ
(40 PJ) and am getting major spewage, looks like the Gulf of Mexico.
