The file 'Natural Gas/Propane Adaptor For Coleman Powermate Pulse Plus 1750 3D Printer Model' is (obj,stl) file type, size is 207.7KB.
Natural Gas or Propane carb adaptor. Fits between the air cleaner and the carb. Set up to use a 7/16 hose to connect to pressure regulator. Gasoline operation is not affected. Will need longer screws to attach airbox and adaptor as the factory screws are very short.
Designed for a Coleman Powermate Pulse Plus 1750 portable generator.
I have several designs I was experimenting with. v2 is what I ended up using. Created a slight restriction and director to help pull natural gas into the carb. Don't know if this helps or not. Attempt to make it easier to start.
Use a material that can handle higher temperatures and fuel vapor like ABS or PETG.
