Yale GLC040 with a Aisin closed loop regulator. Truck had classic symptoms of a bad regulator. Regulator was replaced with new using Yale part number. New regulator had a different tag number and was slightly different with the addition of an adjustment screw on the top. Upon installation, the injector hose was found to be full of tar and the injector stuck open. Injector was cleaned with alcohol and seemed to close. Truck ran considerably better but had flooding issues when starting. A new injector was installed with the same problem. Coolant level is correct.
What does the adjustment screw on the new regulator do? I can find no technical manuals on the Aisin regulators. The screw was was 4.25 turns out from the factory, it was reduced to one turn out and seemed to make improvement but still floods to the point of smelling propane.
Current situation is the truck will start as it should when cold and runs well. With an immediate shutdown and restart it typically starts fine but if its left off for a minute two it is back to the flooding problem.

Yes Mazda engine, 2.0L I believe a F2?
My machine has 2 vacuum switches that vent to atmosphere at cylinders 3/4. Both are clean.
Turned the regulator 3 turns out, no difference in flooding.
Depending upon age, motor. They used a vacuum valve towards 3&4 cylinder This fills up with tar as well and won't run well either. Can be cleaned out with brake cleaner. Has like 1/4 vac line in and out of it.
Turn the vaporizer top screw closed then start out at 3 turns. Should be close. Mazda motor? Psi motor?
That would be the mixture across all RPM ranges? The carb/mixer has one as well but I believe that is just for idle CO?
I have adjusted the regulator screw in which should be leaning it out...not adding excess to flood?
I can check can check for most emissions gasses, but have always been under the impression to set.4-.7% CO and send it
The screw on top of the regulator? Is for adjusting mixture. Should have some sort of emission analyzer to set or laptop for correct O2 sensor readings. In is to lean out. Out is more fuel.
