`87 Spree question

[OneBulletDan]

I have recently purchased a Spree that was worse for the wear. After starting a tear down/complete restoration to find out what sins had been committed on the old gal through the years, I was shocked/amused at the mis-treatment that the bike had endured.

Long story short, I completely dis-assembled the carb. I noticed that the manual shows some kind of gasket or o ring in the float bowl drain screw hole. Is it a regular o ring, or something different?

Thanks for having such an informative site. I`m sure I`ll be back, bugging you guys for info and tips in the future. Please bear with me. As soon as the Spree is done, I`ve got an `88 Elite that is getting the full treatment, too!
