hey gang.. I have a O.S. 55AX that wont stay running.. Twice in flight it died and I landed the plane.. good to go.. Now, I'm bringing the pair back out to see if I could find the issue.. My problem is that it will only run at wide open.. I'm using 15% fuel and no issues with any of my other engines.. Ive put all the screws back to Factory settings [email protected] out and [email protected] out.. its hard to get going at all but, will run wide open, as soon as I start lowering the RPMs it dies.. I thought it may be a tank issue, changed tank and even tried a dummy tank at a much higher than needed position to make sure it wasn't a flow issue.. glow plug has been changed also.. Maybe not hot enough? any help is greatly appreciated..
