Bought one of their carburetors.
$63 with shipping . Came with free 7g weights and a belt . Think Im seeing the same carburetor on other sites a lot cheaper but with the improvement in performance installing it Im happy with it . Thats the only upgrade I've done to the 49cc engine . Top speed has increased about 7 mph compared to stock restricted carburetor .

The ones on other sites aren't a Super Flow though. Calling it that makes the carb believe it's special and if you believe in yourself you can do anything. I'd venture to guess it has so much faith in it's abilities that it would have no trouble replacing a 4-barrel on a 350 Chevy from sheer determination.
If it's a Naraku, as the pic on the site shows, it prob has a number like NK______ something or other on the box. You could use that to figure out what it is. That actually may not be an awful price if it's a Naraku carb.
To gain 7MPH over the stock carb on a 49cc, that basically means the stock carb was way out of tune or something was wrong with it. The end result is a good one though so I'm glad it's working out for you.

I had water in fuel . After resolving that problem still wouldn't start . I ordered the carburetor and had a month of illness and bad weather . Put the carburetor on still wouldn't start . Come to find out exaust valve was to tight . Thing started right up . Plan to check valves like I do the belt bout once a month . Hope to be driving a better more powerful 2 wheel or 4 wheeled vehicle soon .

Unless you put thousands of miles on in a month, checking valve clearance that often is mostly a waste of time and effort. Once adjusted, the clearance should take a long time, months and more particularly, hours of operation, to require checking the clearance. The valve seats should not wear much, nor the valve seating area, nor the valve stem tips, or cam follower tips at either end. It should last for at least 1000 miles before anything would likely be out of adjustment. Then again, what could it hurt? The owners and shop manuals have a recommended adjustment interval, and it is not monthly. FWIW.
