Checking correct fuel level at Round Top 3 screw SU CARBS Float bowls

[jalexquijano]

Any easy method of checking the fuel level in the float bowls of 3 screws round top SU CARBS? My car runs great at high speed but at idle it does not perform correctly.

This is one of the best ones I've seen!

how do you use it? Im calling Bruce at Ztherapy to make an order but cant find him!

 On your three screw carbs, there should be a float bowl drain plug on the side of the float bowls. The "float sync. tools" replace the drain plugs with the clear tube oriented up. The fuel height in the tube is the same as the fuel height in the bowl. same as if there was a window in the side of the bowl.

Bruce and Z Therapy don't have them. I'm the manufacturer and sell them on Ebay for $69.95. I had the same issue as many others so I designed this product. The nice thing about them is that you can check fuel levels with the running or not

Great looking gadget Randalla.  Now we just need better bowl gaskets.  The cork ones really suck.

Check the post above showing my units. The ad is for Z Car Depot, not Z Therapy. Ryan at Z Car Depot is a customer of mine and I believe he may still have a few units left.

how does it work? Just remove the bolt at the front of the float bowl???

I don't want to speak for Randy, but looks relatively simple. It screws in with banjo bolt to the drain port on the float bowl and with the top of the tube open the fuel will level out in the tube at the float bowl level. This give you accurate comparison to balance out the two float bowls for even fuel flow to front and rear carbs thus front and rear cylinders. I wish I had access to this product years ago! Can't wait to get mine and see where I am at on my adjustments. This definitely beats blow into the inlet and raise the float until it stops the air flow method of setting the levels!
