I have a MW 8hp 2speed tiller with these numbers on it I believe they are for the motor which is a B&S
190402 0652-04 74092011.
trying to find manual for the tiller. How and where are the model and serial of the tiller located.
Probably a Gilson 1558B made for M-W. Your numbers are for the Briggs engine. 190XXX is 8hp horizontal shaft; 0652-04 is specific variation (could be just sppecial paint, throttle control, etc.); 74XXXXXX indicates year built (1974).
Thank you very much,
