Ok found another number 80508-1
2270
@Honky Kong jr and @74 Shortbed ---> I've been out of the hi-pro for too long. A 4160, with dual feed, center pivot bowls??? Oh, and no "hard to adjust" secondary metering block. Lmao.

Nice to meet you Joseph. There's a couple other guys around me here. One out there in Bend too, if I'm not mistaken. Hey, do yourself a favor- pick one carb out of all of them. Get a book on that carb, and screw with it. Learn everything you can, even by messing up adjustments. THEN, go learn another one. You say it's bogging at idle- is your timing and other basic stuff on the money?
