Float Height
« on: May 17, 2006, 08:58:32 PM »
I had been getting crappy fuel millage for a while now, and I suspect the float bows are probably set far too high.  Sunday afternoon I checked the level with some vinyl tubing and indeed they were too high ( :cookoo:), so I pulled the carbs and opened them up. Then proceed to a state of confusion (gasoline fume!) about adjusting float height... but I think I've got it figured out!

1. Remove the carburetors... Remember to empty the float bow (I forgot).
2. Unscrew the two screws that hold the float bowl and gawk at the float assembly, things are hold on by o-rings.



3. Holding the carb upside down, start tilting it until the tab rests on the tip but just before the spring loaded tip compresses



4. At this position, measure the distance between the fload and the gasket interface... (picture from Haynes), and adjust accordingly (previous picture). Stock it is suppose to be set at 14.6+-1mm.



Using this method I'm able to get the left side spot on; however I must've did something wrong on the right side... the float bowl gasket leaked a little aftern I reinstalled everything but stopped after a while, but I boughted new gaskets anyway since I'll need to redo the rightside.  Should replace the aging fuel lines as well.

Q: Does the float bowl press on the float assembly and hold it in position? In the first picture the end of the float assembly closest to the camera is not resting against the metal, does that make a difference? ie will the float bowl pressed it into place when it's screwed on?

Yes.  Press it down with your fingers, and then take the measurement.  The floatbowl does firm it up, and seats the o-ring.  Very important.

Excellent suggestion.  Done.
