Carb level, bowl removed, fuel line attached and either gas or water used for supply. The floats were compressed just until the flow of fluid was stopped.

Gas - 14.5
Water - 14.5

Hey, Doc:

Great work here! Good job.

You ought to post this info in the tech section, too, for future reference.

Thanks.

No these are for the good motor .... 1600

We had some discussions a while back. I believe that with the carb upside and the float fully depressed there is really no relationship between that reading and when the needle turns off the flow of gas. However, I'd have to do more testing to see if my theory is correct or not.

Re:Float Levels 10 Years, 5 Months ago  
What I found interesting when doing the stock adjustment was that the reading with gas and water was different. I repeated it to make sure and got the same readings.

Upon reflection I guess it's to be expected as the surface tension of water is more than gas but I did not expect it to be that great.
