Well, I got it.......... Evidently I was tightening the screws too tight. I used some loc-tite on the screws, tightened them in until I could see fuel coming up when priming. It took very little tightening of the screws to make it prime. Learn something new every day..............
Thanks Much for all the replies and the help.
Steve
Loctite on the air cleaner screws was definitely not needed but hey, glad your mower is working good now Steve. Cheers:thumbsup:
