when did it start last?
if a while, get all fuel out and replace with new
if just a few days ago - what has happened in the past couple of days? What if anything has been done to the tractor.
When you say it turns over - at a normal speed? Thus, this is cranking
You glowing the plugs?
Any smoke at all?
Bleed system?
Throw us the info ..... many people will chime in and help - we just need mo' info!
Hi Bryan - welcome to OTT!
I am sure the people here can get you on the right track to fix your tractor. Just a bit more explaining of the symptoms is needed.
