Customer Question

I have a 310000 model engine. Last week it ran fine; when I tried starting it this week it wouldn't stroke through compression.
The battery was checked, connections were checked, removed the spark plug and it cycled, swapped starter and ended with the same results.

Welcome to JUST ANSWER small engines, let me try to help you !! Try adjusting the valves to the minimums, .03 intake, .005 exhaust. But if that does not help, the compression release is part of the camshaft. Briggs and Stratton 793880 camshaft, and the only repair is to replace the camshaft!
