Hi, Private message me with any correspondence or offers. Got a nice Jonsereds 621 that I'll trade for a small to mid sized Husqvarna. (As some may know, I'm on kind of a Husqvarna kick right now). Got a Tilton Super Bar on it, very clean condition, nothing appears to be broken or damaged, oiler works, it is missing the small cover over the spark plug. Anyway, I fueled up the Jonsereds about 2 weeks ago, added some Seafoam, and it fired right up. Idled, revved, and ran perfect. Ran it for about 20 minutes with no problems. Came back the other day, it fired right up and ran perfect for about 1 or 2 minutes then bogged and stalled. The plug was fouled. I cleaned the plug, started it right back up and ran excellent for about 1 or 2 minutes, then fouled the plug soaking wet with fuel/oil mix again. At this point, a carb kit, fuel line, and fuel filter are in order. Give me a few days to respond. And thanks. .
