I screwed up and lost the nut for my Winter/Summer Exhaust Valve. All I wanted to do was replace the nut/star washer.
My problem is nuthing I have seems to fit the stud, does anybody know the size/thread count of said nut?

I pulled my nut off, and as near as I can tell it is a 1/4-27. The 27tpi gauge fit perfectly, but I am guessing at the quarter inch. I cannot find any of my manuals. Should the pointer on the lever be down or forward in the summer?

Most folks run it in the middle, since we never get any extreme weather swings....except for last week w/triple digit temps. I am relived to get the dimension of said nut!

I'd take rc51racer's info over mine. I thought a 27 pitch thread sounded odd.

I pulled the info from the parts manual, also verified with a thread guage.

The boys/mechanix in my repair shop at work told me it couldn't be 27, had to be 28! So that's what I did, already finished up w/ it. Now waiting for my Zenith Carby to make it's way home!
Thanks 4 Everyone's Help,

Mine is rotated all the way CCW, the pointer is facing forward to the right. Since I bought it at the end of summer, I'm assuming that's the summer position. Never moved it, truck ran fine this past winter.
