    I know webers have a hard time on inclines. Wheelers do an angle mod to them for that. Hard to really know for sure what is going on. I wouldn't think you base time would be having that much of an effect unless you're way out of wack. Maybe you're vacuum advance isn't working properly. Oh and I mixed up the marks on the pulley before. After doing that I realized you really don't need to know what you're doing to get one of these engines started. Lmao

    I've been looking into most of what you have mentioned. You getting after fire. You have to much fuel at shut down. The vacuum advance could be a problem for you highway speed backfire but the after fire issue is pointing to something else. I've heard of guys getting brand new weber's and jets were floating around not installed. Maybe vibrations has loosened things up letting fuel past. After you get it sorted outI would invest in a wideband gauge. Use it as a check engine light.
