Review: Perfect replacement. - Bought this for a '71 Honda CT90 and only had to modify the drain tube. Everything else fit perfectly and I was already prepared for the modification, thanks to other reviews and videos. It only needed a bit of fine tuning and the bike was running great!
Review: Not Plug-and-Play - REF: '71CT-90: Like other reviewers, the placement of the bowl drain nipple is problematic. And no mounting stud were provided. Thus, only 4 stars. I followed the advice of the reviewer who plugged the existing port and drilled a new port in the proper place. However, I should have first removed the bowl. I was unable to find a way to clamp the entire carb to my drill press platform, so I used a hand drill. The bit "wandered" requiring epoxy to seal the nipple in the slightly enlarged hole. I had to remove the bowl, anyway, to make sure no metal shavings were left in the bowl (there were) or the passageway, CAUTION: Make sure you remove the bowl drain screw completely before drilling. Instead of taping the original hole, I found a piece of steel rod that interference fit. Tested everything with water to make sure there were no leaks and the drain function worked properly before replacing the bowl. Luckily I had M6x100 bolts available to cut to size and Loctite into place as mounting studs. Once installed, the bike started on the first kick and needed only a minor adjustment of the idle speed after warming up. The hesitation I'd been experiencing with the 50-year-old OE carb, despite repeated removal and cleaning, was cured. Bike runs great. If you're up for the modifications I've described, I'd heartily recommend this as a great value.

### ⭐⭐⭐⭐⭐ Excellent replacement unit
*by C***R on July 9, 2025*

All replacement CT90 carbs are not created equal. I inherited a 75 CT90 with another brand of replacement carb and I could never get it to run correctly. I messed with needle position, float level, and the idle jetting but could never eliminate a stumble just coming off of idle. This carb worked perfectly right out of the box.
