Roush racing has done a propane injected engine check there website and maybe you can find some info.They used the fuel injector holes for the propane injection so thats a start, even though it will require you to weld the holes up then drill out and retap to size for starter i would assume.I hope you can tig weld or you have a shop around you that can.I just re read and saw a carb to be used you will at the least plug the holes but you could figure that one out. Keep us posted though.

Yes, got some ideas but they didn't have anything for what I'm looking for from what I could tell.It looked they only sell propane carbs or dual fuel carbs. I'm wanting to stay away from duel fuel carbs and use a standard petrol carb with a mixer base or a mixer in the air tube. That way, I can get parts anywhere and keep the %110 reliably of a standard 2100 carb

1.
you connect the LPG feed hose coming from regulator which converts liquid to gas, there is a valve on it. it adjust the feeding ratio of LPG when engine is under load. when it is idling, it sucks the lpg air mixture from PCV valve or from similar port. It you will use it with carburetor, you need to use leaf type mixer as you see on my link on previous posts.
2.
Actually i was wondering same thing ,first time, when LPG introduced to me. Internal coolants issue, but.. nothing happens. Just you need to be sure that engine is not running lean anytime. (it can compensate lean burn somehow but you will be loosing performance too - japanese made engines stands better)
3.
you need to find proper size of mixer for your application. Because it restricts air intake at center. (for filter box or for carburetor) but i believe it would be great difficulty to find options in US.
4.
You can operate injected systems with very analog mixer based systems as i explained(i did on my previous car, 1999 V6 3.3 liter pathfinder). you need to add your mixer after your maf sensor and after your air filter, before you PCV valve. also PCV valve will be fed by a parallel hose coming from regulator to make it idle. i will try to find photos over google to show you how later.
