I’ve been looking for a jetting kit for my GT 90 carb but I haven’t been able to find any that are compatible. I bought the jetting kit for the GT 80 but the main jets are too small (they will fit another carb I have for another build, so it wasn’t a total waste).

After breaking the GT 90 build in, the jets are way too big, so big that it wouldn’t run at all. I actually filled the main jet in with JB Weld and drilled out a smaller hole after it cured. Now it’s running again and running much better, but I need a jetting kit to get it running it’s best.

So does anyone know where I could find compatible jets?
