RE: LEO .46 Glow Engine
Sheko,
The link that you put in your last post is not for a glow-plug, but for a spark-plug.
They are not the same and the spark-plug will not fit into the Leo engine.
You will have to locate this item elsewhere.
There are plenty of places in the west that have it.
Try [link=http://www3.towerhobbies.com/cgi-bin/WTI0095P?FVSEARCH=glow+plugs&search=Go]Tower Hobbies[/link] for instance, but only select a plug that is listed as 'Long', not 'Medium' for your engine.
