    Have a 4 year old logsplitter with 8 hp Briggs I/C. Running fine, then just died. By-passed kill switches, no help. Does not have low-oil shutdown. I checked for spark, is none! Engine can''t have more than 50 hours on it. What can it be???

    broke! Ign. coil, short in the kill wire, bad kill switch. With no low-oil shut down that should pretty well cover it.

    Did you check for spark with a new plug? if not do so. If still no spark- disconnect the wire coming down from under the flywheel at the closest point probably at the throttle/governor area. Check for spark again. If there is spark the problem is the wiring downstream from where you disconnected. If still no spark,pull the flywheel, check for obvious shorts visually or a broken wire. By now you should have found the problem. If not replace the coil but they very very rarely go bad.

    Don't forget to check the flywheel key to make sure it has not split, or been twisted if you need to pull the flywheel. Briggs had a problem with that happening, but it usually would occur when you shut the engine off, then tried to restart it.

    Thanks for help folks. Sure 'nuf the lead from the coil itself had a poor connection at the coil. Great! Easy fix, at no cost.
