I have a 69 Ford F100, 1 barrel carburater, the choke needs to be wide open for it to run. When I switch gears, I need to close choke and open it back up when I shift-this is the only way it will run. If I use the gas pedal, it will bog down. Advice please?

You need to rebuild the carburetor. As it is a 1 barrel its relatively easy to rebuild if you can find a kit, but it is the original carb and difficult to find parts. You may also consider buying a Holley 2 barrel carb - it will bolt right on and give you more power, and they are much more common and easier to find rebuild kits and parts. It's possible you may need an adapter plate, depending on the configuration of your intake manifold, but that will be easy to find. You can either shop online or buy from your local auto parts store or high performance shop. That old 1 barrel has had its day and I'm sure it served you well,but I think I would upgrade to a newer carb myself.You may be able to clean it out using carb cleaner spray but it would be hard to clear out that clogged jet that is causing your trouble, and then you will likely tear the gasket when you take the top off that carb.

Sounds like a clogged or leaking jet in your carb try dissassemble and rebuild

HI sound like you may have a bad accelerator pump on the carburetor try this key off engine off air cleaner remove look stray into the carburetor throttle and open the throttle by hand see if fuel squirts out like a small pressure stream hope this helps .
