Does anyone here have a recommendation for a good Weber tuning shop in the Denver CO metro area? I moved to Denver about 18 months ago from NH (at roughly sea level), and I probably ought to get the Weber 40 DCOEs on my '74 GTV rejetted for the 5300 ft altitude here. Car runs OK now but is rich I think, so could probably be better set up. If nobody has shop recommendations, I could probably tackle this myself if needed. I've never been inside the Webers before but I'm handy and as a bicycle mechanic am used to small and fragile parts. Thanks for any tips!
