Carb Help needed

I am just having a true bugger of a time getting my floats right. I am trying to bench adjust the floats, and i cant seem to get them just right, always too high or too low. Anyone in the shouth jersey area that might be able to lend a hand?

if not just some suggestions. I have been testing he carb then draining all the bowls, flipping them over, pull the bowl o, then use a small screw driver to bend the tab a little bit, thn put them back together, and flip them over to run another test.


any suggestions would be greatly appreciated.

 

Yea, this is a real tedious task and truly requires a feel for metal. Best advice I can give is to remember that this steel springs a little so bend so little that you are not sure if you moved the tab at all. We are talking about moving the tab in tenths of a millimeter increments.

 

I put mine in a workmate table, leveled them and then did all my adjustment thru the opening in the workmate table. That way you don't have to keep flipping them and leveling them.
My wife bought me the cheap workmate table at Walmart I think, pretty cheap.

The table has crankscrew adjustments and you crank it like a vise, pinch the carbs in it and you can access the bowl srews and floats from the under side.

Like Bluemaxim said they are very touchie.

 

A much easier way is to sit the carbs on top of a glass container full of liquid to check the floats instead of putting on the float bowl.

 

Here's another way that keeps you from having to remove and replace the bowls each time: Invert the carbs and remove the bowls, make a paper height guage (business card or card stock works well) at the correct height (17.5mm for 750s I believe) and use the template to check at the highest point of the float. This requires that the floats be straight with reference to the hinge pin (both at the same height), and that there's no dirt or leakage on your floats causing them to sink or stick. The template has to pick up the gasket face of the carb body at two points and the float AT ITS HIGHEST POINT. This gives an excellent visual confirmation that your floats are even, and makes it easier to make those tiny adjustments. Really helps for those .5mm height adjustments during tuning...
Of course, you should confirm your heights using the tube method before hanging them on your bike.

 

listen to Lodollardave...this works good!

 

Hi.

That's the way I did my floats and to date it's the only thing that has been easy.

now am i supposed to do this with the floats submersed in something, or am i supposed to do this with the carbs inverted.

 

Inverted from what I can understand

 

thats how i see it, i cant figure out what the proper measurment is. frmo the top of the bowl? or what.

 

oh geez, jsut realized you wrote it in the post. i will give it a shot

 

cant seem to get the proper measurement.
