carb problems

[jacksonp32]

so recently (about one week ago) I purchased a 1970 beetle, 1600dp w a 34pict3 carb. we trailered it all the way from Eugene Oregon (sea level) to Fort Collins Colorado (5500ft above) I am new with the carb thing, but I have a basic idea on how to adjust using both the volume control and bypass screws. I got the idle to just about perfect, and adjusted the mixture screw to where it was about right, and when I drove it and put a lot of gas, it stalls. It seems the carb is bringing too much fuel in and flooding the engine. so I continued adjusting when it appeared the exhaust was spitting out fuel. I'm not sure what the issue is. unless there is a special way to adjust for high altitude. any help would be appreciated. sorry if I sound a little dumb
thanks

No this does not sound dumb.
Please post more about the engine, take a photo and add it to your gallery.
Tell what distributor you are using on the engine. Have you adjusted the valves, oil change etc. What type of air cleaner is on the engine.
I live at 6400 feet elevation so can related to what some call high altitude operation. However to me high altitude is like 10,000 feet.

OK, moving from sea level to higher elevation means that the fuel amount will stay the same but the amount of air getting in is less due to the elevation. So the air-fuel ratio will differ from the optimum.

Since you can't do much about the air, you must decrease the amount of fuel accordingly. I'm not sure just decreasing the volume of fuel with the screws will do enough to help you. You may need to decrease the main jet size so less fuel gets delivered.

I live at 1000 ft elevation, and my 1970 never had any driveability issues when I went to 5500 feet (Prescott) or 7000 feet (Flagstaff), whether with original 1600 SP with PICT30-3 or later with 1835cc DP with single Weber.
