The motor is a 6603B-E01141<br />It cranks up and runs as long as the throttle is above shift and the mixture control is screwed all the way in. If I turn the throttle up to fast then I can open the mixture a very little bit, otherwise it has to be screwed in all the way. When throttleing down to the shift position it cuts off unless I use some choke. The lowest I can go is a hair below the shift position (with half choke), then it cuts off.<br />Are parts available for this motor? I don't want to start taking it apart if I can't get the parts. I feel like the carb needs a good cleaning, or maybe a rebuild.<br />Also, can someone tell me the procedure to set the timing?<br />I would also like to replace the impeller.<br /><br />Thanks in advance for any help you can offer.<br />Dee Seegers
