My motor is overdue for a carb(s) cleaning. I am pulling off and cleaning my carbs and when I removed the bowls I noticed my floats look like they are sitting at a weird angle. They still float so they aren’t “heavy” or taking in fuel.
My question is to anyone with a service manual or any insight, what is the correct float height for these carbs.
Its a carbureted Vmax 150. I think the part number for the carbs is 64C-14301-S2-00....
Thanks
I believe when flipped over (needle valve closed), the carb float top should sit level with the carb body.
AND, be careful when adjusting them. Don't put a bunch of pressure on the needle valve / seat.

Is the model of the motor unknown? If so, how about the primary ID number?
If we can figure out a way to find out the model or primary ID we can then get to all that needs to be known.

Thanks guys
Will let you know when i get home. I rebuilt mine last year. If the measurement is not done right when you pump the fuel bulb, fuel will come out of the carb.

911, I cant tell you how much I appreciate you getting that for me!!! Thanks man!!Originally Posted by yam911
And Thanks as always to BBC
From my experience with other motors, this is one of the most critical measurements, the motor will not run correctly if the float level is incorrect.
Well, since I’ve had it it has never reached 5500 RPM no matter what motor height, prop pitch...etc. Not that I want to run around maxed out all the time but it would be nice to know it’s running right and able to hit WOT RPM. It has also intermittently surged at mid-high RPM more than a couple times. My floats were definitely sitting higher than the 16mm. Abnormally high. Makes me wonder if the floats were replaced in the best and never adjusted. Maybe if will run better when I put it back together...fingers crossed
***in the past, I mean
Hey, i'm going to tell you dont worry about running wide open all the time. I have many hours on mine wide open and no issues. I have made 35 mile runs wide open one way. As long as you use ringfree to control the carbon buildup and dont exceed the rpm limits...there should be no problems. But yes, once you get all your measurements correct and reinstall them carbs i would also do a "link and sync" to make sure she is at her prime.

Thanks to the advice here, I am happy to report that after adjusting my way out of whack carb floats my motor that was only maxing out at 5000 or 5100 RPM, I actually hit 5700 today at one point with my M23 prop. Service manual says 5500 max on mine.
Thanks for the help. Love when it’s something simple!!
