A gen set with the inverter technology ? The old 5.6KW set is well, almost 30 years old and used hard some winters, while the Tecumseh motor has been more or less trouble free, it uses more oil now that before and Im sure I could find a HF clone to fit, but do I really want to go that route? So looking at new gen sets his inverter thing is coming up, which costs more. So do I really need to go that way or just stay with the old school set up?
