Is that tube touching the carb?

Your float Could be higher, but I don't know how it being set a bit low would affect the performance.
BUT!
If there IS a reason, someone will post it.

should be...


Lower makes it leaner.

yes ,I'm also trying to figure out how lower makes it leaner.

Vercy ,I think that's a stretch,the fuel in the bowl ,with it's straight sides has the same surface pressure (14.7psi)and the same surface area,. at it's present level as it does if the level was correct. and the carb is pulling the same vacuum.the difference in flow would be immeasurable .for example if you had a pipe 100 ft tall filled with water the pressure at the bottom would be about 60psi,the pressure 1/4 of an inch down would be 14.712psi ,so the difference in height in the level is twelve thousands of a pound ,and gas is lighter than water so will be even less.

Adjusting the float level on the Savage isn't necessary on a stock motor with stock air cleaner and exhaust - the factory setting work just fine.  Adjusting the float level is however a common tuning practice on the CV carb, and the procedure is listed in most tuning guides for CV carbs.

Here is a quote from the Factory Pro jetting guide:

To get best low-end power, set float height (fuel level) so that the engine will accept full throttle, without missing or stumbling,  in 2nd gear from 1500 to 2000 rpm at minimum.

Float heights, unless otherwise specified in the installation guide, are measured from the "gasket surface" of the carb body to the highest part of the top of the float - with the float tang touching but not compressing the float valve spring.

If the engine has a "wet" rhythmic, soggy area at full throttle / 1500 to 2000, that gets worse as the engine heats up, lower the fuel level by resetting the float height 1mm greater (if the original was 13mm - go to 14mm). This will lower the fuel level, making full throttle / 1500 to 2000 leaner.

If the engine is "dry" and flat between 1500 to 2000 rpm, raise the fuel level.

It should be noted that this adjustment is for "full throttle" use at low rpm - the float level adjustment doesn't have a lot of affect for the idle circuit.  (The situation where the float level has the most affect is when the throttle butterfly is fully open and the slide is only being partially opened by the engine vacuum).

Dave,I don't really know if my bike has a "WET " OR "DRY" rhythmic area in 2nd gear @ 1500 to 2000 rpm ,@ 11 to 17 mph I'm not in 2nd gear or trying to  go to wide open throttle,nor do I think I could feel the difference lugging the motor that badly.Where this may apply to four cylinder race bikes I don't think you could use this tuning method on our thumpers . The pro was talking about float heights of 13-14 mm our float heigths range from 26.4 -29.4 mm ,I think we're talking apples and oranges here.Have you ever really used this method to set a CV carb?
