"My two-cylinder Yanmar has apparently got poor compression, and takes its own sweet time to start -- worse in cold weather. I understand the starting fluid (ether) approach is not a great idea, and I don't have any glow plugs. But I figured pre-heating the air at the air cleaner ("silencer") ought to help, and it sure does! I used my heat gun (set to low) and the thing starts with a few turns, rather than only after 30+ seconds of grinding.
So, the question is, am I doing something horrible? I know I'm only treating a symptom, and that the compression needs to be fixed someday. But am I making anything dramatically worse by starting the engine with heated air? (I'm certainly avoiding battery drain, starter over-work, and possibly backing up cooling water into the exhaust manifold.)"
