Hello, I recently have acquired a 1992 Daihatsu hijet climber. It was running good at first, now it doesnt seem to hold the idle. I have to give it a shot of throttle every so often to keep it running. Anyways, I wanna do a tune up to it. Im ordering distributor cap, rotor, plug wires and spark plugs: https://minitrucks.net/products/daihatsu-tune-up-kit?variant=36545498677398 Now, it says to verify the distributor cap part number and order the correct one from the drop down list. Mine currently says B-1. I dont see that option to order a new one. the options are A-1, A-2 and B-2. how important is it to match that number? any help appreciated!
