It was nice having the PZ30 carb on the cart with so many more aspects to control with the jetting. But the performance was starting to act a little erratic after 800 miles. With the cheap Chinese manufacturing, I didn’t have high expectations on longevity.
Before going back to the Keihin that came on the GX390, I thought I would try the 24mm 3 circuit carb from VC.
Getting the epoxied, broken off low speed screw out wasnt that bad with some silver solder and a spare PZ30 jet. Ugly, but it worked.
The flux made a mess though. It came of easily with some carb cleaner.
The low speed screw on this 24mm carb is a different size than the Keihin/clone carbs. Since I had the solder out, I used another jet from the PZ30 and made a “new” screw from the original. The PZ30 jet provided a nice shoulder for the spring.
All cleaned up with the adjustable main jet.
On the cart:
It fired right up and with just a little time spent adjusting the jetting, it is running pretty well.
