New floats are they pre-set?

Post by Rapid Dog »

Got mine in the box. Are they preset or should I have to fiddle about with the tangs?

I've replaced everything on these Bings, float pins, float needles, jets, cleaned everything, yadda yadda.
Just cobering all the bases as I've had trouble getting the right side float 'level with the bottom' without it overflowing.
Had to bend the tang down further than the other carb...

Rapid Dog, I'm not sure I'm reading your post correctly. But first, in answer to your question, you should expect to "fiddle about with the tangs" on new floats. Even if the floats were "factory adjusted" correctly, something may have happened to them in the handling between the factory and you. If the new floats are adjusted as prescribed, and you have fuel still flowing, something unusual is going on. I would be very interested in the condition of the float needle and seat in that case. (editing: and also if there might be some trash above the float needle and seat)

Something in your post (highlighted by me) caught my eye. Are you talking here about your experiences that led to you ordering new floats, or are you talking about your new floats? If you're talking about your old floats, I've gone down that road a couple times. I've experienced carb overflow on a couple of bikes and have attempted to fix the situation by adjusting the tang on the float to that magical position where the overflow is cured. And I've motored off happily, only to have my boot wetted again with fuel. In the end it always took new floats to fix the problem. Aligning the new float seams to be parallel with the carb body has always kept my boots dry.

As an aside small digital scales are pretty cheap nowadays at Harbor Freight and your favorite office supply store. It's very interesting to compare the weight of a new float with a heavy float. (Plus the scales are very useful for getting the right ratio of resin to hardener.)

As a second aside, I keep a pair of new floats in stock because I know I'm going to need them someday. And when that happens I won't want to wait for the UPS truck to bring me new ones.

In my sample of one - I put new floats in the R65 without adjusting anything. They seem to be fine.

Along the same lines as Ken: I wish I had bought two sets as my other bike emidiatly started dripping. I am sure its acting out over jellosy. I only own the two bikes, so I probably won't buy a spare when I buy the next set.

When you finish adjusting the floats, you should end up with the tang of the float bearing ' Straight' onto the float needle, this is a little bit more complicated than just bending the tang upwards!
