OK, borrowing a 1996 Honda TRX300 to plow my driveway.  Started it once, no problem.  Second time after trailering it from original location in cold weather - 4 hour trip, it would not start.  Brought it into dealer, they had to replace solonoid, ($204 bill) go to pick it up dealer mechanic starts it no prob.  Put it on trailer, bring it home 10 minute trip.  Go to start it one hour later, starter is turning engine over, but it will not start...very frustrated...any tips on how to start this stubborn machine???  I have tried choke in multiple positions, fuel guage and tank cap switch all in proper position, lots of fuel in tank...help???
