Thanks for the input. Following Steve's process...the AH motor starts. Seems like I hear the fuel valve open (at this point when it is working you can hear the "whoosh" as the fuel ignites). When not working you just hear the motor continue to run, then shut down. I would guess it is an ignition problem because as Steve said, when it does finally fire, (after trying it several times) I get the big cloud of white smoke. Yesterday when it finally did fire, once the smoke cleared, it ran perfectly. Nice and clean. I left it on overnight and all day today, flawless.
Ed, so are you saying take the Wabasto off, hook up the igniter on the bench and supply 12V to it repeatedly? Would a car battery work? I don't think I have any 12V Makita batteries anymore.
Thanks for your help guys. I have a couple more things for which I'll need the Forum Expertise. One thing at a time though.
