Carburetor Adjustment Tool DIY, Float Height Gauge - Honda CB750 | Part 28

But I used some recycled plastic from an Ice Cream carton.

In this video, I make a float height gauge and set the floats for my CB750 K0 restoration project.

Setting the float heights can be a little fiddly, so making a gauge to set them all the same really helps.

I discovered that Honda recommends not putting the carbs upside down, but at an angle so that the float tang is just touching the float valve rather than fully compressing it.

The measurement is from the rim that the float bowl seats into, not the gasket face. For a Honda CB750 K0 the measurement is 26mm.

I appreciate the tutorial, my '73 ran fine but had a leak from one of the brass overflow tubes plus float height was off. I got another bowl with no leaks, made a gauge, and no leaks. I'll re-sync the carbs tomorrow. Has fresh rings and cylinder hone plus lapped valves, which was all the bike needed at 33K miles. Did the work myself and it is oil tight, runs strong and has no smoke out the exhausts.
