Thanks for the reply.
It's a Briggs & Stratton Intek V twin 20 hp.
Engine would spin but not fire, yes.
I got the dang thing running though.
I checked the gas tank cap and seemed super tight, so I loosened it up a bit, and it started right up.
Obviously the cap was so tight the vent wasn't letting air in to allow it to pull fuel to the carb.
I'm sure I'll have other issues soon though.
This mower is my problem child.
(and yes, some of this is user error. This is my first riding mower. I'm a first time home owner and didn't have to cut the grass much as a kid)
I'll be back!
