hello I am working on a daewoo gc20s3 that is a lpg unit and I have all sorts of missing when cold and intake backfireing on high load. I recently rebuilt the impco cobra regulator. it had ran fine for about 2 weeks and then was running horible again. hard to start hot or cold.
It is easyer to start when cold. If it stalled out when actuating the throttle when cold and wont restart I can turn off the fuel and crank it over and it will eventualy start. I checked the regulator to make sure its not freezing up but found it is hot as it should be. recently did the cap,rotor,plugs and wires the same time I did the regulator rebuild.
Anyone have a starting point for me. I do not have low pressure guages to test out pressure on the regulator. Anything will help at this point. Thanks!
