If you used a screw driver to open the carb, you probably have an elec. controlled carb. The carb is contrlled (to the best of memory) by a variable pot on the accelerator, and by an ECU (small black box w/ 12 wires). Be sure #1 wire is tied to neg. coil. You should see the carb. operate w/ the key on, when depressing the accelerator. If that operates, then your just not getting fuel.
Follow the fuel line from the tank to the 1st valve. Is it elec. or vacuum operated?. If elec. check to see if the soliniod operates and allows the fuel to flow. Remove it supply powr, and see if you can blow through it ( there are easier ways to check it).
If vaccum oper. there is a small vaccum hose that operates the valve and allows flow, check that.
Next is the convertor, the diaphram on the carb actually *** fuel from the convertor( the convertor has an input line at the top, 2 water lines in the middle, and 2 lower pressue fuel lines on the bottom, one is plugged)
Note: LPG fuel is pressured at 300lbs, is -40 degrees be careful.
Sometimes our customers get a bad fuel tank. when they replace tanks, a black quad ring comes out of 1 tank lodges inside the screw coupler, and wont allow fuel to flow from the new tank.
I also have some trouble shoot info.

Fact of the week
The dot-com bubble, a period of large and rapid investments in internet-based companies, peaked in 2000 and saw the Nasdaq Composite index rise by 579%. Then the bubble imploded. As the value of tech stocks plummeted, cash-strapped internet start-ups became worthless and collapsed.
