Problems like that don't bother me I work in a machine shop I can fix that problem. I also grew up with a mechanic for a father plus I been around cars, tractors, and engines all my life its simple stuff.   I am in no rush to find one... When a good deal comes around I'll pick it up.

The cold start kit uses a manual fuel primer that pumps a small amount of diesel fuel into the thermostart, which is mounted into the intake. The thermostart heats up by engaging the switch, thus igniting that small amount of diesel fuel. This helps to ignite the fuel in the cylinders as the engine is cranking over. It is intended to be used temporarily for starting the engine only, which is why Bolens used a push button switch to heat the coil in the thermostart plug.
 
I found this video on Youtube of an HT20D that has a homemade cold start kit installed.

There are several other videos regarding thermostart systems there.



That's cool but at first sounded like the battery was low on charge but never the less if that was a option that's kool

Thats my ht20d. thermostart did help some

 

 

This is the critter I'm talking about:

 

 

If that isn't the cold start kit, then what would it be called, and why isn't it listed in the attachment interchange lists?

 

My spare engine had this heater but it ended up melting.  I think the rough start in the cold threw my injection pump timing off and i haven't messed with it in years. it sits in the garage collecting dust until i get around to it.
