Help identifying an engine....
 

Hello all, new to conversions and I recieved a free "Weed eater 1400" from a co-worker today. I stripped the unit down and
the motor is unlike any I've seen here yet. The carb (walbro) mounts the the bottom of the crankcase and is contained inside
a plastic "box" for lack of a better description. I know that a lot of newer weed eater brand stuff is built with Poulan motors
but this thing is apparently 15+ years old. Any idea what it might be? I'll post pics later on tonight.

they don,t make good plane engines , some of them even turn backwards and have no power if this is the wedeater poulan brand

Ok, here are the pics I took of the engine. it has a 46 cast into the outside of the cylinder and a reed under the carb mounting. Is this a 46cc ? I'm not so much worried about putting this particular engine on a plane, rather it's going to be my introduction to doing conversions. Rather ruin this freebie than one I might pay for.

don't wast the time on it if you plan to fly a plane, if you want to just do it for the sake of doing a conversion have at it.

I would look for a newer model like the feather lite 25cc it would actually be usable IMO .

Ken, thanks for your input. I'm starting to think this might be a better paper weight than anything else. :) Too bad really, as it looks pretty stout on the
inside. Pretty beefy components. Would the carb be worth salvaging?

Also, whats a better motor: Homelite, Ryobi, or Poualn? I've heard lots of good things about the Ryobi motors and Homelite, although it sounds like the conn rod in the ryobi is riveted? I plan on using my gasser in a 5th scale Pica WACO somday so I'm not looking for vertical or anything.

Thanks again!

P.S. For curiosity sake, is this a 46 that I have?

RE: Help identifying an engine....
 

either of the three would be good . on the ryobi I wouldn't worry about the rod unless you plan to make a twinn

RE: Help identifying an engine....
 

Make a TWIN?! Man now you really have my ears perked up! Where can I get info on making a twin? Do folks use stock parts? or do you have to machine your own crankcase and crank? I have access to a machine shop so this might turn into some real fun. Got any links?

Thanks again for your help.

ckovacs
dont forget that" beefy" and "stout" also translate into heavy,thats not what we really want
big enough to do the job is more than adeqaute anything else is just weight.
on the ryobi the crank shaft is riveted not the con rod ,the con rod is stamped steel
string trimers and blowers run from small (around 16-18cc)up to 31cc like ryobi( not backpack
blowersI have found them to be too expensive too tear apart .) larger engines usually come
from chain saws and scooter engines .polan and homelite are very popular up to around 45cc or
so . for an inexpensive ryobi try harbor freight tools , usually 50.00- 75.00 will get you a good ryobi
to start .there are also parts suppliers that make conversion parts for the more popular engines .
