Generac will not start / smell of gas

Thanks for the input guys. I failed to mention this is on a Toy Hauler that has a fuel station on board. I currently have the trailer back at storage and will get out there this weekend and (1)check for spark. (2) Clean plug and replace filter. I'll post back my findings later in the week.

If you have a strong smell of gas, it could have got something caught in the needle and seat for the float and over filled the float bowl and flooded the engine. Pull the plug and see if it is gas soaked. Clean it with an air gun and try it again. Also check the air filter, if it is real dirty, it will also cause it to run rich and flood out the motor.

Do you have spark? Check the simple stuff first.

if on a mh ,they shut down if the main tank gets to a quarter of a tank.pull the plug clean, or change ,they do go bad.
