Without the toggle on the solenoid will never engage. Also on this forklift another mechanic wired in a toggle switch for the electric solenoid lock off valve. We were able to run the engine with the forklift propane tank valve off. When we had issues with the original regulator assembly we used a tiger torch with a flow valve so we could control the flow of propane into the carburetor. Regarding your test suggestion I will submit some more info you may find valuable. I will reseal the original regulator assembly and see if that changes anything. When we purchased the new used regulator we also bought a rebuild kit. With that said I don't discredit your suggestion. I contacted the seller and he only used it for a short period of time before finding out that he had a dead hole on his engine thus the reason for selling the regulator. I have thought myself perhaps the supposedly new regulator was faulty. To date we have replaced the coil with an aftermarket coil, replaced all spark plugs, cleaned the distributor cap( non-points style ignition with magnetic pick up with vacuum advance), replaced the battery and tested the following components. It sometimes seems like it will almost fire and other times just cranks. It's giving identical symptoms as the original issue. It tries to start but will sometimes backfire and then just die. Fast forward a few days and now it won't run again. The ambient temperature during this has been anywhere from 35*f to 60*f. There seemed to be a lag in the throttle response but otherwise it ran as per usual. After the engine warmed it would idle fine and run properly. We ran the engine at part throttle until it warmed then adjusted the idle. It would run ok but die if it was allowed to "idle".

After we installed the "new" unit we started the engine but only if the throttle pedal was at full throttle. If you use an external propane supply (tiger torch forcing propane into the carb) with the carburetor intake pipe removed from the top of the carb the engine would run and operate properly.Īs such we replaced the Aisin convertor/regulator assembly with a good used unit from eBay. Long story short after countless hours of troubleshooting we determined that we had a fuel supply issue.
After a few more days it wouldn't start at all regardless of what we did. It smelled like it was running super rich. It would only run at half to full throttle otherwise it would die. Recently he complained that it started to run rough and smelled heavily of propane. The engine utilizes an Aisin carburetor and Aisin convertor/regulator.
My friend has a Toyota 42-4fgc25 forklift with a Toyota 5r engine.
