I was just curious if there are any differences other than the choke, and what year that changed.

I have an 88, a 90, a 91, a 95, and two 97's, but I'm not sure what all's been swapped over the years. The 97 and 98 of my buddy's are the same, but if I want to order a used OEM carb what years will fit this 97?

Hey Goober in the picture of the starter valve there is a washer on the top of the picture that looks like it is hollow on the bottom, conical shaped where does it go?
i got 1 in my Shindy kit.

in this post go #48 then click your link and then go #25 in your post to see the picture I'm talking about.

Hi Tony
Can you post a pic of the carb you’re working on?

I can break out my spare carb and starter valve.

There’s no oring on the starter valve kit other than the conical ring on the valve itself. But I’ll look in case I overlooked something

Ahh i see what you mean
I attached a pic
No i do not know what that last piece is shown on the starter valve. The diagram may indicate that the seal exists but it is integral to the starter valve and not replaceable.

Sofar as i know there are only four orings on the carb that are replaceable from the kit: pilot jet has a small and tiny; bowl drain has a small and carb bowl has a large with integral small seal for the primer pump.

the part you have circled ?, thats the o-ring that goes around the valve.

BTW that 86 starter valve oring (comment above) was too big for the 93 starter valve.
I may have ruined the oring because the smaller 93 starter valve bore cut the conical surface.
Oh well a lesson learned about swapping parts
