Default Running on LP

I have a FB zd that I am trying to run on lp. The carb was broke so I cut it off flat and JB welded a 3/8 lp fitting in it. I also took out the butterfly valve since the governer weights are broke, and jb welded up those holes. Now the problem is I can't get it to run. It will fire usually 2 or 3 time and quit. I can crank it over again and it will do the same thing every time. The gasket between the carb and block has a small leak could this be my problem?? No gas appears to leak out when running with a small amout of gas comming out, but it will leak if I turn the gas up to high. I have a high pressure regulator(21.8 psi) with a shut off valve after it to control the flow. I have used a low pressure secundary regulator and had the same problem. Any ideas??

Hello from Wisconsin!!!
My opinions!!!! You should have a secondary regulator to drop the gas pressure to about 11 to 14 inches water collom, what a common gas grill regulator does. Also an on demand regulator. This works like a needle and float in a gasoline carb, shutting off the fuel flow when not needed. I think that you have so much gas that you are in effect flooding the engine. Thats why it starts, fires once or twice then stops. Hope this helps.
