Hi I have been trying to locate a manual for a 14.5hp briggs and stratton I/c quiet ride on mower motor. Model no. 287707 type 1224-D1 code 990526ZD (unleaded)... it is in a yardsman. I went onto the briggs site and could only the parts listing and the manuals for 280000 etc but not for this particular motor. Can anyone PLEASE help. It is urgent I can get this. Thank you for your help.

The series is what you want, the 280000 is what you need. It will have the info for your engine. What is your problem with your engine?
