I have a 2004 hustler super mini-z with a 24 hp Honda engine. The engine is having ignition problems. With about 70 hours i lost spark. It became intermitent, sometimes running and sometimes not. I need to get this running for the spring and summer. I also have the bac-vac for it. A lot of money, should run. No one has wants to help, just wants money. It was out of warranty by about a month or 2 when this started. I checked it today and was able to get spark to the rear coil, nothing from the front coil and yes i switched the plugs back and forth. So, I am thinking the coil. But, what about the diode? Coil is $60 for the front and about $30 for the rear. Diode, about $40. It is not the oil switch and does not appear to be the wiring cluster (nice name for all the wires and relays). I would appreciate any help.
