will 87 nq50 carb work on 89 sb50 motor it looks the same but I don't know

thank you

It would bolt up but there are differences:

The SB50 carb has an oil inlet on the carb body itself. The 87 NQ50 carb does not. Oil on the Spree is injected into the lower of 2 taps on the intake.
IRC there may be slight internal carb part differences, NQ50 vs SB50 ran a different carb tag. If you have a SB50 parts carb around plus take care of the oil injection tap, a swap should work out.

thanks mousewheels the prob is that I have 1989 sb 50 elite and the o ring for the air gas mix screw is bad and I tried to order it from 15 sites and nobody can get it so I tried on ebay no luck the scooter is in great shape 1000 miles and when I got it running it ran good for a week. After a week it started to sputter so I took the carb apart to clean it when I noticed the o ring sb50s r hard to find carb parts for



thanks again for the help

You could probably take the o-ring out of the other carb, put it in yours and continue to use the proper carb.

Couldn't you just go down to an auto parts store or industrial supply shop and just drop a quarter for a new oring to fit?

This.

Take the carb and screw into a good hardware store that carries a selection of o-rings and get a new one.
