Float height setting

[richh]

Hi Guys

Is there a “good” way of setting the float heights on the B model carbs?

The bike is starting and running but the carbs are flooding

Cheers, Rich

Hi Rich

Have you checked the float needle is seating and shutting off properly?

The best way to check the float levels is by connecting a clear tube to the drain outlets. With the carbs horizontal and the tube held higher than the float bowl you will see the level of fuel that is in the carbs. This can be measured and checked against the settings in the manual

I got that method but wondered if there was a “cheat” method?

Sorry Rich it’s the only way I know

Trial and error. Mostly error. One of the biggest PIA’s going that is. You can either flood it or have it die when you yank the throttle. If it doesn’t do either, leave it alone! I’ve go an MP3 somewhere of mine dying on a high speed run as the fuel just couldn’t keep up. Must dig it out, it’s a cracker.

Anyhow, good luck, you’ll need lots of that.

Hi Lonesome,

it is either the fuel cock filter or an aftermarket inline fuel filter.

Clean the fuel cock filter and remove the inline filter.

Hi Guys

I set the floats spot on with a tube.
Left the bike for a couple of weeks (been super busy since I bought it) and it pissed fuel out of the overflow as soon as I turned the fuel on.
It has all new jets etc so I thought the float needle may have a rust flake or similar holding it open. I stripped off the carbs(again!) and found the brass float full of fuel. AH HA !!!
now I know why it keeps flooding.

Anyone got a spare brass float?

Cheers

Rich

At least you know what the problem is,They are not difficult to repair with a bit of solder once emptied.

Sorry for the delay, but I have many spare floats if you need one.
