TOPIC:

I think I have the pickiest float levels in the world, I spent 4 hours working on the 75 kz400 Saturday, adjusting each float level at leats 5 times. I ended up with the option of no fuel coming out or lots, depending on how I bent the fuel valve tab.

So now it runs, but it idles at 2k. I expect part of the problem is pods. Maybe I can cut down the pilot air flow somehow to drop the idle.

Soon, maybe today I can take it out for the first tirde of the year.

I got it out for about 10 harrowing miles, it was surging and stalling, and the engine stopped a few times. I think more carb tinkering is needed.

I've been through this also, I use the clear tubing attached to the drain screw port method, works for me. What levels do you set yours too? I try to set mine just a few mm beneath the top of the float bowl.

Inside my VM36 Carb bowl is a line indicating the proper fuel level. I set it 1/16" below that wet.

For pods you will need some rejetting. I recently did a friend's 76 KZ400. The carbs were bastardized by someone before we started and some jets were drilled out too big to use.



Now using:
Uni Pods
#35 slow jets from a 1970 Honda CL350. (the number looks like 35. The emulsion holes are bigger. The stock KZ pilots may work, ours were drilled way too big to use.)
#35 pilot jets
#68 (89?) starter jets
#132 main jet (Drilled out the Honda #100 jet to 132)
#90 pilot air jets
#60 main air jets (these were the stock #40 drilled to #60, .6mm)


On second thought, you may be better off ignoring these jet numbers. We were working from the standpoint of fixing someone else's screw-up. Starting from scratch, you probably just want to get some mains that are about 4 to 8 numbers bigger and see what your plugs look like after idle.


THE MOST IMPORTANT THING IS TO MAKE SURE THE PLASTIC SEALS ARE ON THE JET PORTS SO THEY DON'T GET GAS and the orings on the jets need to be good. You can still buy them somewhere.

Part # 28

pilot plug rubber

You know, the plastic plugs are old and don't seal well, I should get some more, as they didn't come in the rebuild kit.
