China carb
Carb showed up real quick. First impressions, it OK but has some minor issues.
The throttle arm was loose on the shaft. I had to stake the end of the shaft (see pic) and add Loctite. Since it was loose, the idle speed screw didn't line up well to the arm (see pic). It was OK after I staked it.
I had to bottom out the idle mixture screw to smooth it out. Maybe it's the stepped needle and it prevents a lean adjustment but I prefer the normal technique for adjusting mixture. Main adjust seems to work fine.
I had to bend the governor rod to a right angle where it mates to the govenor arm. It also didn't come with a needed "e" clip. No problem, I have a kit. I do really like the adjustable length governor rod, very handy. The original is not adjustable.
It runs well so far but I need to figure out how to set high and low speed. It revs and idles too high. It was a $15 ebay purchase from "usadirectsupply" out of CA. For the price I can't complain but so far I count 2 minor defects.
Now that the original Walbro is on the bench I may try to bush the throttle shaft to keep as a spare.
