Hi, welcome to the club

where are you located? perhaps in a particularly cold climate?

i've never been a fan of webers, had them for years and even when you get them running perfect they only seem to last 6months before falling out of tune to the point of coughing and spluttering, and i've never pulled one apart that those little diaphragms wern't perished (even brand new replacements)

all that said, you do get great top end power with them, but at the sacrafice of low end

even on the rally car we went back to the twin SU style GX induction, and never looked back, so reliable and such even power delivery, you just need to find an old mechanic capable of getting the right needles to set them up
