40 xls compression problem solved THANKS ALL
hello to all again , well i took the engine to a freind from my club who has been flying for 9 or 10 years and we checked it over, turns out the glow plug was bad.at the center of the glow plug where the small rod comes thru the glow plug was very loose, it had broken and the air was escaping thru it, thus no compression. i put in a new glow plug and it now has the same compression as my other 40 xls
