Topic: Carbs $uck

I don't think that measurement is terribly critical anyway. As long as the fuel level is a few mm above the main jet that should suffice.

Oh, could someone kindly post a picture of this clear tube attached to drain screws please. I don't understand how you can have tubes and screws in the same hole at the same time.

I agree that the float level can vary just a little but not more that 1 mm.

To answer your question about the drain screw and tube.
You have to start with an extra drain screw. then you drill a hole through it large enough for a i inch long brass tube. Then you solder that together and put i in the float bowl. You then attach a short length of clear tubing.

You fill the float bowl scribe a line where the GAS level is. THIS IS AFTER YOU have adjust the float level with a gauge as described in chapter SIX of the Clymer's manual Page 125.

Then you can scribe the other three float bowls for a reference.


BUT WHY DO ANY OF THAT? Just adjust the float levels with a gauge and forget it.
Do you really want to drain all the float bowls and put in that special screw you made to each carb, fill them all with gas and re drain all of them again to check each carb???
NO.

I've checked mine once, didn't need adjusted and don't foresee ever having to adjust them in the future.

LesterPiglet..That measurement is somewhat critical because although the gas is slightly above the main jet, sometimes the bike my be leaned over  for a few seconds and the main jet may not be able to pick up any fuel if the level is too low.

[LesterPiglet]

Which is why I said a few mm above the jet, to allow for lean.

I have to say, I've had my K6 since 1978 and I can only recall having the carbs off twice in all those years, and I can't remember the last time as it's been so long. I've never put any kind of kit in them. the ONLY thing I did was add an inline fuel filter WAAAAAYYYYY back in the early 80's.

What a horrible unreliable POS, don't know why I've kept it all these years

Yes I think you need a much more reliable motorcycle. Something that will last 33 years ,you can still get parts for it, and it is pretty much trouble free. A 1976 CB750!!! LOL..lol..lol

I went back and looked, Nope sorry.

You are a good guy though!

Did your bike blow up 3 years ago or something?

Lucky once again The air in my bowles is not traped they have a common vent and it will NOT matter about the hose. The fuel will allways be the same level in the tube and bowl. You will have to do better than that

Quote from LuckyThe length of that tube is important for that short length and the reason is that the float bowl has air in it. When the gas goes into the float bowl that trapped air can cause the level to be higher inside the tube.

On page 60 of the Clymers manual
There is only one room in or out of the house for a Clymers (Comic book)

Lester is correct  I don't think that measurement is terribly critical anyway. Just don't go above the gasket and I wonder if that is the OP problem.

I'm afraid I did say a few mm above I just didn't add "to allow for lean" Stop being pedantic.

Just go to page 60 of the Clymer's manual and you will see in the picture that the scribed fuel level line is no where near the top of the float bowl.

This is causing many problems for forum motorcycle owners.
 Float bowls way too full of gas.

Please go to chapter SIX  (P. 125) and learn the correct way to set your floats.

LesterPiglet has it right.

Let me go to the outhouse and see if I can find that Clymers

Don't they have Haynes manuals in the US? A much better book imho.

We have those as well.  I use a Honda Shop Manual, Clymer Manual, and HondaMan's Book (when working on the 750).
