Chainsaw Repair

I suffer from an age old disease that runs in my family on the male side;  its called "I just can't help playing with things".  All things, dirt bikes, street bikes, cars, trucks, big and small....stock is just never good enough. I drew a line on my work saws, so other then simple repair, I keep my hands off. I always had that itch though, so I jumped into it. When I'm done the current one I'd like a 70's or early 80 big saw. I don't really need anything @ 100+ cc's but that probably won't stop me from using it for kicks. Most work around here is small to 25" with the couple times a year 28" to 35".  Every so often someone wants something bigger dropped that's making them nervous. Anyway, I've seen a lot of saws for sale that have caught my eye. You can definitely get a better deal by browsing for what catches your eye then setting your sights for a particular saw...from what I see. But for me, whatever that next one is, its going to be 100cc +.
