Chainsaw Repair

You can down load Jennings if you want to .I'm not sure if you can Bell or not .

There's a lot of good stuff in both of them that I can't remember off the top of my head .They'll tell like how to figure time area open at certain perspective speeds and stuff like that .What good ports should look like and not so good of ports too and why they aren't so good .

What you have to watch is both of them as well as McDizzy get into motorcycle and snowmobile engines which have a larger crankcase volume  than a saw engine .If you just stick to the basics though won't have any problems .
