will a 60b work on a

[collectivepitch]

i have a older 91sx . will the 60b carb be enough for that engine or do i need something else?

If it will fit in the crankcase it will work. Now I doubt you will have full power potential from the motor using the 60 B carb. I believe the bore on the 60B is like 9.5 to 9.8 mm.
The bore on the 90 size carbs is 10.6 to 10.8 mm.

which one would work better? 60m or 60k?

[DavidH]

60 K is what is on the OS 91 C Spec.
60M is what comes on the OS 91 C Spec PS motor. This is the motor that use the Varsane/Perry pump.

60K with Cline and big bore mod is what I use on my Cspecs.

You know, any part will work, all you need is some imagination and skill :twisted:
