Morrow will not start just back fires


Backfire is a timing issue. The flywheel on those motors controls that timing. Check to be sure that the woodruff key is not missing and that the flywheel is lined up correctly.

12 hp briggs backfires doesn't start


This could be a result of several different things, however the most common of these would be a sheered flywheel key. If this is the case it has throwed the motor out of time and is trying to fire while the exhaust valve is open causing the backfire and lack of compression to start. I hope this has helped.

I can't find any thing on my my riding mower


This machine was made by Murray who is no longer in business. Briggs and Stratton purchased a majority of the company and a lot of the parts can still be purchased through Briggs. I do not see a parts diagram for the (b) series but I was able to find one for an (a) which is a year older machine. I have included a link for the parts diagram of it.
