When installing the Kerosene starter in the P60, please note:

The P60 glow plug boss may have damaged threads near the combustion chamber.

DO NOT FORCE THE KEROSENE START UNIT IN AS IT WILL SURELY BE DAMAGED. This is due to the fact the P60 glow plug boss is tig welded on instead of being brazed. In some cases the weld penetration distorted the threads deeper then what would affect the glow plug but would damage the longer kerosene start unit. We would suggest that you return the engine to JetCat USA if this is the case.
