AOD, the tree guy brought four Husqvarna saws, two 335's for the high up, one handed work, one that was around 50 cc's but I don't remember the number, and the 2101. He was a little worried about his Dad's reaction to the failure of the 2101 but I assured him that if they decided to fix it I could count on some AS friends to help come up with parts.
JR, check the sprocket nose to make sure it is free, then clean and check the bar grooves to make sure there are no chips or junk caught in there to cause it to bind. It is possible that Rich just put a bar and chain together and the gauge doesn't match. Feel free to bring it down and we can look it over together if that would help.
Henry, Thomas already said it but the 81 should pull the bigger bar if you don't push it too hard. Certainly a skip chain would help in a big log like that.
The 55 was a recent e-Bay purchase; actually had been advertised as a "Super 250?". I contacted the seller and asked them to look for numbers on the bottom and discovered it was a 55. Won the auction and received the saw a few days later. Checked the spark, very strong, checked compression, honestly 180 PSI and I thought those kind of stories were made up. Put fuel in the tank, a little prime in the carburetor and it was running. I didn't even touch up the 9/16" pitch chain, just laid it into the log. The governer (air vane type) is currently disabled and I must say I was really impressed with the way this one cut.
Have a look and the spikes on the bottom of the full wrap bars. Does anyone know if these have a special name or purpose? I don't think I've ever seen any like those.
