My Intek 14 HP was becoming a real slug.... got to the point where I was having to slow to a crawl for just slightly tall grass. To make a long story short...... found barely any lift on the intake valve. Local shops are backed up 4-6 weeks, so I tear it (the engine) down and find the intake lobe on the cam is almost a perfect circle! Ordered the cam and various gaskets/seals and re-assembled. WOW! I forgot what kind of performance I used to have. The new cam has a slot cut across the gear side journal...... (looks like it's for some kind of aux. drive?) I'm not too crazy about it, but that's the number it got supersceded to. This engine is right around the 2 year mark, mowing 20 yards +or-. With the situation at the local shops, and performing the repair myself, do I have any recourse with Briggs for rembursement of parts or labor? It's not a lot, but this should not have happened.... the rest of the engine looked great.
