1997 Suzuki King Quad idling problems

[Chet]

My neighbor who had hip surgery 6 years ago parked his King Quad in a shed and it has not been fired up since that time. He replaced the battery, but could not get the unit to run. He asked me for assistance, so we towed the unit over to my shop. I got the unit running, but could not keep it idling without turning up the the RPMs...and when I tried to drive the unit it seems like it ran out of gas after a couple of hundred yards. I tore the carburetor out...dropped the float bowl and discovered a bug (about the size of a housefly) in the bottom. I removed the bug...cleaned what jets and other components I could, put the unit back together...with the same results. I once again removed the carburetor...have removed the plug for access to the pilot needle adjustment and I am preparing to dunk the whole unit into a can of carburetor cleaner. I cannot get the diaphragm screws loose and was wondering if that would hurt the rubber diaphragm if I just left it on the carb...and what should the pilot needle adjustment be set to. Any help would be appreciated.

P.S. What should the fuel switch under the gas tank be set to. On-Pri-Reserv

Take a dremel to and cut a slot across the screws in the diaphragm cover then remove the screws with a straight screw driver.

Set the petcock to pri, this lets fuel flow all the time not just when the engine is cranking.

Did you check the float for movement and make sure it doesn't stick? The pin can get corroded.

Thanks...removed the diaphragm, removed all the jets..soaked the whole carb in carb cleaner...still have a question regarding the setting of the pilot needle adjustment...it is a mikuni 19BE K681...pilot was set at 3 turns out, but the unit still is not idling right...since I removed the plug for cleaning I now have access to that adjustment...any clues

Thanks

Chet, Thuds4evr here.

I have been following your post and am wondering if you solved the idling problem .

I am new to the forum, do not know that I will be able to contribute much as I see the guys in here are a long ways out in front of me on 4 whlrs. It sure is great to see how quick they are to jump in and offer help though. Have been other type forums that this sure was not the case. Tom
