I picked up 2 mowers at the scrap yard yesterday. One Murray had this engine on it. The frame was broken and the starter wouldn't catch but I got it anyway. I spray some WD40 on the pawl that engages the flywheel and got it working, sort of. The entire starter assembly is plastic, not a plastic cover over a metal one. It's held down by three small bolts but one of the nuts they thread into had broke out of this one. The whole starter housing was flexing a lot but I managed to get it cranked and it ran alright. I put it on another frame but need to figure out some way to get a third bolt in that housing. I am disappointed in Briggs for this plastic starter assembly. Thought some of you'll might want to see it, this is the first one I have had. Looks like my pictures are to large.

The plastic starter has been used for years on the Honda GCV engines and MTD's own engines. it is nothing new. When you said it broke out, do you mean the starter housing is broken or the stud has broken out of the engine block.
