Wayne,
Since you have flames shooting out the carb, you know that you must be getting spark. Make sure that the fuel pump is working. You can take the fuel line off of the carburetor, and put the end of it in a can or jar. Then you can crank the motor over and see if it pumps fuel. Make sure that you remove the coil wire when doing this so that there is no chance of a spark igniting the gas. The next thing you need to check, is the gap on the points, as this can affect the dwell, and the timing to a certain degree. If these seem to be ok, then you need to check the ignition timing.
I would suggest that you purchase a repair manual (around $20) for the Jeep. These manuals give step by step instructions on most repairs, and tests such as timing, and can come in handy for future trouble shooting. They can be purchased at most auto parts stores.

Experience
40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range.
Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland.
Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
