I have rotator manifolds for Homelite 33cc and 38cc engines. They are custom made for Walbro carbs. I would sell you one for $20.00. I convert Homelite engines and often have them listed here on RCU. Here is a link if you are interested in seeing one of my manifolds on a Homelite 38cc engine.
FYI: I also have the following conversion parts for Homelite engines.
rotator manifolds for the 45cc Homelite with the round style intake.
Aluminum Engine mounting rails
Polished Aluminum Prop adapters with counter threaded prop bolt for using Aluminum spinners without the need for an adapter.
Polished Aluminum Mufflers
Gaskets, Piston Rings, Cap Screws, Carbs, Ect.
All of my parts are the highest quality you will find! I have a very skilled machinist who uses a CNC mill and lathe to make my parts.
