I bought this for a built 50cc 2-Stroke engine. Nibbi makes a good solid carb, inside the chamber is polished, chrome plated, and looks nice. My only gripe is that it is a pain to get tuned. The needle has a different taper than my usual Keihn/Mikuni PE, but getting this thing dialed in just right took time and patience. Outside of that, it’s a great carb and has performed well. Worth the cheaper cost to have to fiddle with jets.

Looks good and extra keys and all parts are. Nice but Allen key screws so big negative there

I restored an old dirt buggy with a 150cc engine and got tired of messing with the cheap vacuum-driven carb. Decided to put a "real" carb on it. Did some research and determined that I should use the smaller-sized carb. People seem to think a larger carb is always better, but I think a larger carb only helps with top end speed. Using a smaller carb will give more low-end power, which is what this buggy needed. So I went with the same size it came with - 24mm. I also bough the NIbbi intake manifold and filter. However, the intake opening on this carb is like 48mm and the filter is also 48mm (I think, could be off a little on either) which meant the filter did not fit on the carb. Nibbi didn't seem to make a filter that fits this carb exactly. Plus, there wasn't a lot of room behind the carb once I put it on. I had to run a piece of tubing from the carb intake around the frame and then mount the filter to the tube. Not sure if that impacts performance or not.This carb comes with a couple of different idle and main jets. Using the pre-installed jets, if I gunned the throttle the engine bogged to a stop. I let it do that and took the spark plug off after it died and the plug was wet so I put a smaller main jet in. It seemed to get slightly better but still dies when I gun it. I still need to do some tuning.Anyway, I am very impressed with the build quality of this carb. It's very well made. I think I'll get one for my scooter as well. I just don't trust the electric chokes and vacuum slides on the Chinese carbs. Would rather have a mechanical choke and a real slide.

Positives ~ The construction is on point. ~ Quality materials & clean machining of its parts.~ Relatively easy to install. Depends on the workspace (lots of room to work, or right quarters?).~ tuning - access to jets & adjustment screws are easy (positive) makes "tuning on the fly" easier.~ Great value for the money!Negatives ~ sometimes not all the correct parts are included - incorrectly sized intake boots, incorrectly sized o-rings in the throttle cap & fuel drain bowl - clogged or undrilled jets. This is really dependent on who originally put your package together at the factory...~ tuning necessity - sometimes it takes swapping different size jets to tune the carb to elevation, air temperature, fuel flow - but this is always dependent on engine size & compatibility! Sometimes this is the necessary evil of matching a carb to your motor.Some are lucky to "plug 'n play." Others are unlucky to have to spend hours rejetting & trial-and-error getting it to tune correctly.

You need to buy extra parts to get this carburetor to work, unlike the plug-and-play mikuni carburetor.
