Hi. I have a Poulan 3700 chainsaw for sale. I did some tinkering with it today to get it running and fresh gas and it is running very good. It has a 20 inch bar but it could use a new bar and chain. I've only run a professional mixed gas in it that you can purchase at Advance Auto. I will also include half a can of that type of gas. I'm asking $80 bucks.
