Hi guys, with your help I found the model number, type and code for my engine. I now know what spring I need. Thanks Boobala, the link you provided does not list my engine. I did look at all the ones listed but none of the carbs look like mine. I need to know where the spring goes when I get it. Model 10T502, Type 0457 B1 and Code 07102551. Thanks to all.
Robert
