Re: [Amc-list] Water line in six cyl. intake

[Tom Jennings <tomj@xxxxxxx>]

Yeah, the little motor barely breathes and CFMs, it's hardly touchy 
about carbs as long as low velocity mixture is good. I swear the 2bbl is 
just for marketing.

Frank had a nice dual carb setup on his, he said no real difference. I 
meam let's be real -- at 60mph in 3rd-over it's pumping 96cfm maximum! 
That's not even half the flow rate of a Carter YF! It's like a big 
lawnmower, if it weighed 600 lbs.

Maybe I should try the one bbl...
