Chainsaw Repair

Sharkey, never changed the battery in 12 years. It's on my log splitter and that lives in a heated shop, so it doesn't see cold weather.  I use it primarily to track hours for maintenance and not as a tach.  But sure got that 044 dialed in nice with the el cheapo tach:  13,500 full out and purring nicely at 2700 idle.
