I picked up the 125 today and as soon as I got it loaded up they guy is trying to buy it back!

After about 4-5 mins it just stops running. If I wait about 20 mins it fires right up until it goes for 4-5 more mins. Thinking fuel/carb related. It's like someone turns the key off, doesn't seem to be choke related. My game plan is new autolite 216, rebuild the carb, condenser, and check the coil.
I know what you all want
