| I bought a Miller Bobcat LP welder/generator that ran the same way. Did everything you did checking regulator pressure and was within spec. But ran rich and loaded up on fuel.
Went ahead and chiseled the cover off the the supposedly non adjustable regulator and it turns out it was actually adjustable with a stupid tamper proof cover. Leaned the mixture out until it started missing, turnrned back in 1/2 turn richer and it now starts and runs like a striped......well you know!
Anyway adjust your regulator and it will likely be fine. If you can't adjust your regulator buy one for a turkey fryer as they are adjustable, fixed numerous gas grills simply by replacing the worthless non adjustable regulators. Same principal for your engine. | |
