You know briggs shop manual does have a starter draw bench test (tested off engine),right? If that passes starter's probably good, so a possibility eliminated there, which would leave compression release (as someone noted,stick a feeler gauge in and look for the ACR bump while turning engine) or sheared flywheel key,other than that you got internal binding (rod ,crank, or cam starting to seize, counterbalance seizure, bad bearings, etc) ,provided voltage drop is done right (or simply jumper cables from a good strong battery direct to starter and engine block to see if it still cranks hard)dennis wrote:Thanks, all, for the good information. I did a voltage drop test and it was fine. I didn't do a starter amp draw test because I figured if there was too much compression because of bad ACR, the amperage would be high, just like if the starter gear was bindiing or bad bushings. I'll try that anyway, and maybe get a new or spare starter.
