Recently, my 2CT has become hard starting. I've been pretty good about adding anti-gel conditioner to the fuel. Last week, it really didn't want to start, it took me about 20 minutes to get it to run. I figured it was because of the cold weather and I hadn't run it at all the day before. Since then, it hasn't really been cold, but the engine has been a bit hard starting and idles rough for about 20 seconds. I figure it's missing on 1 or more cylinders until the cylinder temp gets up enough for a good combustion.
Without any diagnostics, I'm thinking one or more glow plugs may have become weak or gone bad. Anybody have any insight on part numbers or where to find glow plugs for these engines?
