It is sad because the 1050 is a year out of warranty and shop has had it forever because pushrods were on back order. I called them today and learned that the new rods bent in 5 minutes of operation. Now he said they sent the cam out to see if it is bent ... really? I they now what they are doing.   [Reply]  [No Email]

I just put 2 pushrods in a Briggs twin that a mouse had totally insulated the left (#1) cylinder with fiberglass insulation. The overheat condition bent both pushrods on that side of the engine and froze the valves in the head.   [Reply]  [No Email]
