I'd like to put a word in for the Weber DGV down-drafts. I bought one, with
a Sr. IV manifold, in 1987 from Rick to replace my CD150s. It has run great
for a dozen years. The only trouble I had was remaking the Sr V linkage to
fit the Weber. Took some doing, but I got it to work. I hope someone has
come up with a linkage kit since then. If someone has, please let me know.
I don't know how much extra punch you would get with a Weber side vs. down.
I'm confident our beloved Yoda of mechanics Jarrid can tell us. But unless
you need it, I'd go with one of the Weber down-drafts. It is "set and
forget" and a great "bang for the buck." I would really like to hear from
anyone who has used the 40/40 down-draft that Jarrid has written about.
Please believe me, if I had the money and the need, I would already have
side-drafts bolted on to my 1725. But for my everyday driving (and I mean
every day) my DGV down-draft is great.
