I have a 20HP, 42 Lawn Tractor
Model 917.272910 with a briggs& Stratton 407777-0167-E1 engine
The last time I tried to start the mower it started lilke normal but then the rpms went extremely high sounded like was going to blow up. What would cause this and better yet, what should I look for to fix this problem?
I need to get fixed soon so I can put my son back to work.
