So what y'all want is a battery operated (cordless) saw with the power of an SP125, weight of a MS150, for the price of an Earthquake, and it'd be cool if the battery never needed to be charged. Right? I'm headed out to the shop. Let y'all know how I make out.
The more you add, the more that can go wrong. OK, to remove the pull start means adding an electric motor with enough torque to turn over the engine and start it. We are cutting wood meaning we are working at something that is not easy anyway; do we will need an electric start on such a small engine? It makes sense on an automobile because of the size of the engine; I don't feel that the added expense and potential trouble of an electric start is justifiable in a small engine such as a chainsaw. My mower doesn't have an electric start.
You don't need that on a chainsaw, I thought that was what children were for? When I was in 5th grade and started to learn about the Civil War that was who I thought I was named after, but my teacher informed me my middle name was Scott. I always thought it was after Ulysses S Grant , but what dad was really calling me was Useless; as in "Useless, come over here and stack this wood."
Stihl has come out with an inertia electric start on one of their backpack blowers. Sounds like a B-17 cranking up on your back..... Electric start on a saw isn't so far-fetched. McCullough did it back in the 80s. Worked quite well too.
