I was able to get a second Bolens Ridemaster yesterday. It has a Briggs engine. I am pretty sure it will run but have not tried to start it yet. The number is 38AB301, I did not find a manual for it in the manual section. It has a t-handle under the tube behind the pivot point of the tractor and looks to go into the back part of the drive section. What does it do? My other tractor does not have this lever. My other tractor is a 35AB02 with a Wisconsin engine. Thanks and I will post a picture later today.
