Hello from New Hampshire... Have got almost 2 feet of snow over last few days. My 07 550 SWT with only 500km is having a rough begining to the season. It would hardly run at all yesterday thought it could be the 10% ethanol fuel that has sat in it since March so I drained it out and refueled. It is MUCH better now... drove it for about 20 miles this am and is running great at all speeds exept at idle. It will stall as soom as you stop . The only way to keep it running at idle or slow acceleration is to keep the choke shut ? even after the motor is hot it must have the choke shut to idle??? Any suggestions ? Should I run carb cleaner through it ? Spray in ? or add to fuel type ??
Any insight would be greatly appreciated ! I did change the plugs and it made no dif at all.... Thanks... Mark
