So cool air travels from the flywheel up and out the frog skin but it won't cool as it goes by the fins?
I'll let you know if or when I'm wrong
The cool air can't go by the fins if it comes out the frog skin first. Think of it like taking the top cover off and running it. then all the air goes straight up and not by the motor to cool it. Great for hot starts until the motor is seized. With the hole in the fan side a percentage of the air from the fan is being diverted from going across the cooling fins of the motor. How much I don't know, how long it will last, I don't know either. I can rebuild it though if it doesn't pan out for you, I do know that.
Not trying to be argumentative here towards you here Clint, I just hate to see you burn up your saw is all, trying this. As far as I know after the triangle hole fix from Husqvarna no hot start problems have been reported.
