Topic: Setting the float level

[Spanner 1]

Thank you Kong.... no  'diss' intended to anyone from me

Get yourself a couple of feet of clear quarter inch aquarium tubing.  Cut off 4  lengths of it long enough that you can slip one end over the overflow tube and then wrap the tube into a 'U' shape with the open end sticking up about half the height of the carb.  Next open up the carb drains, with the petcock open.  What will happen is all 4 of the little tubes will fill up to exactly the same level as the fuel in the bowls.  So if your floats are set right and working right all 4 of them will be 26mm below the float chamber rim.  But if one or more of them is leaking you'll see a considerably higher level on that or those tubes.

This is a good idea, Kong.  I will be using it in the future for sure.  Thanks!

Yes it is Kong you should post that in the tips and tricks section. I've been looking at the kit for $14 but this is way cheaper and available from Home Desprate.

made mine for the change under my car seat.
carefully heat the middle of a 1' section of the tubing, and as it warms, stretch it out.
cut it in the smallest tapered stretched area to make 2 pieces.
screw this tapered end into the bowl drain screw hole if ya got em.
secure the tubing upright next to the bowl.
test fuel height as described above.
works like a charm.

Oh, can you send me the full sized version of this image?

Thanks everyone. A lot of good info posted here. I should be able to sort this out this weekend, me thinks.

This is not good practice.  The carbs need to be layed down and positioned so the float will just rest against the float needle without depressing the spring tab.  They shouldn't be inverted either because the weight of the float will depress the spring and give you a false reading.  The guage or the positioning of the carb rack should not put any pressure on the float.  You want to lay the rack air filter side down, like this.



Put something underneath the rack so it doesn't tip.  You want the float to be able to just rest against the needle without putting any pressure on it.

I found this helpful when I was rebuilding my carbs

Good luck with it

If you just get the same id tubing as what goes on the float bowls, you can slip it on the bowl and just crack open the drain screws rather that trying to tap a rubber hose into the drain screw hole.

Yep, and you just loop them up and look at the level, like a sight gauge.  If no fuel flows into one of them you may very well have a valve or float stuck in the up position, if one is a good bit higher than the others it may have a float valve that isn't sealing or a float that has sunk like a stone.  Anyway, if three of them are at one height and one is way higher or lower, well, it don't take the brain of a Purple-butted-baboon to see something needs taking care of in that carb.
