Weedeater Conversion
 

I am looking to convert a Weedeater Featherlite 18 cc motor out of a garden blower. Does anyone know if there is a kit of parts available for this engine or will all the bits need to be made up as I go? Hmmmm, maybe a good excuse to buy a lathe.

The 18cc may prove disappointing...
 

... it does not have a lot of power. If you can find it's 21cc bigger brother, now that is a good power maker, not to mention the Weedeater is the lightest of the small industrial grade gassers.

You can get the parts for the 18 and 21 featherlites from Carr Precision as well as parts for the Homelite, Ryobi, and McColluch engines... All you need is the hub and the mounting backplate. The existing muffler is fine if you gut it out and put a bigger outlet on it as I did.

I have some of these. One is a hedge trimmer and one is a weed whacker. They are nice running engines when used as they were intended. They start easily, are easy to adjust and last a long time.

The third 21, I converted to a model engine. I cut all the shroud webbing off and took the fins off the back side of the flywheel. These engines are much lighter than a Homelite. I used a Homelite 25 carb on it.

These engines have the smallest ports of any of the weed whacker type motors other than the Homelite 16. They just don't make enough power to overcome their own weight unless you are good at porting. Mine turns a 14-6 at 7,000 rpm. I've never used it in a plane.

Your time would be better spent on a Ryobi 31 or Homelite 25?

Enjoy,

Jim

Thanks for the replies. I am looking to replace a glow sized .90 with this motor, do you think it will have enough power to do this? I usually fly electric power but for the bigger planes I would like to use petrol power. The reason I won't use glo fuel is that I hate the clean up after use.
