Installed a weber 32/36 and right out of the box it ran smooth, but lacked acceleration, bogged 2nd through 4th, was barely able to hit 55 and bogged hard on hills. Checked timing, it was at 0 degrees BTC. Installed new plugs, timed to 5 degrees btc and set lean best idle and now it pulls great in first and 2nd but has a wicked carb back fire in 3rd and 4th. Especially on hills. Downshifting to 2nd stops the backfire. There is a mild exhaust backfire when i downshift. Any ideas?
