Unit is a little H30.

Currently fighting a nikki vaporizer.

Started with hole in radiator, and poor running lift.

Replaced radiator, waterpump, t-stat and cleaned coolant system.

Still iced up vaporizer. Heard a propane leak out of it.

Pulled it and took it apart, full of tar and diaphragms were hard.

Ordered rebuild kit, cleaned, replaced all parts put back in lift and it blows propane out of a port on the bottom back side (flat side of unit opposite where coolant passages are.

Took back apart, can't find anything wrong. Literally no one around me has even heard of a nikki.

Not sure what to do now.
