How much 270 and why aren't you using them......?
Rule 1 always be suspicious of the opposition
$550 U.S will buy you a pair (matched pair, same jets and slides in both carbs!!
) of dellortos with cables
Or better still, Walter will sell you a set of carbs for around $20k,
They come with a free EML and a shitload of spares, including Kroeber ignition!
