I have a Toyota 5FG30 dual fuel truck with an Aisan LP regulator. If the truck sits for 3 to 4 hours it is extremely hard starting, however once it has been started it starts right up after that.
I know that the Aisin regulators were not the best. We used to replace them with adjustable Beam 60 regulators but they are now only availabe as non adjustable.
I have 2 questions, 1. -what is causing it to start hard and
2- can I change the regulator to another brand, like Impco, that would be compatible with the existing dual fuel carb?
