I bought this generator about six years ago and only used it as backup power for my pellet stove so it's only got about three or four hours on it total. Since new it has always been a bear to start, requiring six to ten pulls to get going and most times I'd have to give it a shot of starting fluid when the temps got below freezing. I've always meant to replace the plug after discovering it was a China special, but never did as it always looked good when I performed the annual maintenance on it, and the generator always ran well once it started. So over the weekend I stopped by Napa and picked up an NGK plug and swapped it out. Three mornings now the gen has started on the first or second pull with just the choke and with temps in the teens. I know, I know, I should have replaced the plug years ago.
