Hi Dave
I have had those carbs on my eBay watch list for a while, seller did not respond to my enquiry asking him to confirm what carb size and whether he would ship to Canada.
the seller being in Bulgaria freaked me out a bit, but he has excellent feedback, and that starting price would be a smoking deal if they are RS 36's, just 12 hours left to go as I post this.
as the seller didn't respond to my enquiry, I won't be bidding (maybe he just doesn't want to deal with shipping to Canada, who knows), but good luck in your bidding if you can find out or figure out what size they are.
