Mitsubishi FG40K No Start

Model FG40K
S/N AF29C20310

First off, unit is dual fuel. Went to bring it in the shop today so i can rebuild a mast cylinder. Found a crank/no start concern. it tries to start and even smells like propane from exhaust some. Even though it has a full bottle, I swapped just in case. same thing. crank/no start. Even thoughi didnt see any obvious selector switch for fuel, I added a few gallons of gasoline in case it was empty. Still crank/no start. Has spark. Seems to be getting some fuel given I can smell what appears to be propane in the exhaust.

Any suggestions? Is there a fuel selector switch hidden somewhere so i can run it off gas only or at least try to?

Not sure exactley where on your truck the switch will be located but places to look if it still even has one(if it hasnt been removed by someone and converted to straight lpg only)....is there a switch on the dash??...other places are to the rear of the truck close to the radiator support or on the sides...as for the no start...because you smell propane i would check to see if it is getting to much propane PSI..sounds like the vaporizor may need rebuitl..if it is the impco vaporizor the fuel psi should be around 2-3 PSI coming out of the vaporizor and to the carb(air/fuel mixer).....
