It would be a shame if it was, Aaron. I have a 375 which has the 3700 top end and it is a really nice runner. It is a very low hour saw and pulls very hard - I am not sure a 3800 would be better.
I mentioned earlier I recently found a 3800 with a 4000 top end. I have spoken to the guy who bought it new and he swears it has never been rebuilt. Perhaps it came from the factory that way? Anyways, I have cleaned it up and am very pleased with its performance. I put new seals and fuel lines in, cleaned the carb and removed the base gasket. It now has 150lbs compression - same as my 375. None of my other 3400's are higher than 130lbs - even with new rings and one with the cylinder base turned down. I didn't touch the muffler as that extra side port seems sufficient. It sure sounds nice. Will post up some pics when it cools a little
I have been indulging my Poulan fetish lately by visiting mower and saw shops in my region - with varying results. At one, the owner (who I went to school with) gave me a real nice 3700 in return for some Solo parts that I have. He is happily keeping an eye out for me.
In another town I went into a shop, happily paid $2.50 each for some Oregon tie straps to get the subject on to saws and buy a bit of the owner's time, then asked him about Poulans. He pointed to a Poulan in the back of his shop that was either a 3700 or a 3800. On asking if it was for sale, he told me he was going to throw it in the dumpster. He said all Poulans were rubbish and he'd be doing a disservice giving to anyone. I argued gently - even begged a little. No go. Finally, I asked if he'd keep saws for me when they came in offering to pay a fair price. He refused. As I left he showed me his large range of Stihls and I had the pleasure of turning down his offer.
