Checked the choke on the Weber carb and it is not closed. I went ahead and replaced the vacuum line from the carb to distributor; but the one that was there did look fine.
Ran the vehicle for 15-20 minutes in driveway and ran smooth, no missing. Took it our for a drive and initially seemed OK in 4th, but when you really give it throttle, no response, even bogs down and backfired a couple of times.
Could this be carb related. Have had the Weber on for at 2-3 months and never really experienced this before recently. However, mostly used to work and back where I never had to get down on the accelerator (like when passing). I adjusted the idle speed and idle mix on the Weber, but that's all the adjustments; not very versed in adjusting carburators.
Any thoughts ro suggestions?
Thanks
