Float adjustment

[robertpage101]

1986 johnson 175. I read my manual and just checking if I have the right info. It says set float at 1/32 of an inch above gasket.
One more thing is does this hieght change at elevation? Boat came from Tx and im at around 5000 ft elev. It came from a old boat guy. Boat has ran fine since I got it but think its time for a tune up. Thank you for any info!!!!

Re: Float adjustment

floats would be set the same the only thing if your running at 5000 alt you can run leaner main jets which would help it run better at that alt

Re: Float adjustment

I read that in fact the float is set level with carb assy where the gasket lays.

carb cleaning instructions???Johnson/Evinrude
these are directions for 2 cylinder, 2 carbed motors, but the principle follows for most other carbs.

Cleaning Carburetors First i ask you to follow the directions in your OEM Manual.

1. you will need a rebuild kit for each carb.

2. remove carbs trying not to disturb linkage adjustment.

3. dismantle carb, and place in carb clean solution, soak over night. ( do not put plastic parts in solution.

4. remove and clean the orifices (jets) high speed is usually behind the bowl drain plug, the slow usually top center of carb body, you will need special tool # 317002 to remove the orifices, or make your own. pictures below.

5 using compressed air. Blow out all orifices, with a small wire ( 2 or 3 stands of wire from an old extension cord) make sure all the jets are clear.

6. reassemble the carb body, with the carb up side dowm set the float parallel to the carb body.

7. complete reassembly,
