Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I was recently given a Powerlite.  previous owner had a friend change the spark plug and totally stripped it out.  I took the head off and put a helicoil in, afterwards he told me to keep it.  It starts and runs great.  How do i determine if the paddles are worn out, what gap between the blades and housing is too much and where is the best place to buy them?
Thanks,
Packo

I found the wear holes and they are worn to the top of the hole.  Looks like a great idea elongating the bolt holes...THANKS
