My old Poulan 306A runs ok until it gets hot. After hot it quickly dies out after started and needs choke to keep it running. I also have a 245A which runs very good until it runs out of gas. After refillng, it is very difficult to start and doesn't even fire. It acts as if it is flooded. I heard the coils on these older models sometimes quit working when hot. Any suggestions on my problems. I have a new stihl which I use for general purpose, but use these old saws on my chainsaw mill.
Thanks in advance.
