I made a ryobi good engine.
I made a poulan 46 great engine

Now I want to make a 60-70cc engine to power a 1/3 stoudacher that will weigh about 20lbs and I want good 3d power and I think a engine this size would be great.

What are you using for a converted engine around this size and how much does it weigh.Do you have any pictures?

ps

I want to do a conversion, I like to tinker, please no coments about, just go buy a zdz or bme etc.

I am thinking about converting a Ryobi for my 25% Edge 540. How does your run? Are they dependable?

the edge will be under powered with the ryobi,I use mine in a dynaflite flybaby. use the poulan 46 and hold on ,The poulan only weighs a couple oz. more, mine is in a
h9 1/4 cap

Just go buy an RCS engine, that's your best bet.


Sorry, HAD to do it.

bn120: Is your 46 poulan a smooth runner? What props do you like. Is the engine smoother with wood or man made material props. I said it that way, because I do not know all the different materials used in props. Did you use the pro or standard series engine? Thanks Captinjohn

How about looking for a husqvarna engine. the last 2 numbers of a model are the CCs as in model 3120 is a 120cc or 7.3" a 272cc or 288 would be super. Tyr ebay and search "Husqvarna saw"

Homelite Super XL or XL 12 make a good engine in the 50 60 cc range I have two on CH ign. One on a Christen Eagle.

OK here is what I ended up with 2 stihl 56.5cc a 49cc and a 91cc I bought them all for 10 bucks from a local lawn shop,I already choped up 2 of them, the older one with the magnesium case is 3.25 lbs and the other is 3.5 lbs it is made more like the poulan 46 I have and the us35 also.
need to give ch a call to get ign. when I get it going I will let you all know

ps I cant wait to get my hands in to the 91cc this thing is huge ar ar ar ar ar

captain my poulan likes a 20-10 prop and with the velocity stack it runs all so smoooooooth and will tick over as low as a engine with ign. mine has the mag but it has timing advance

bn120, Thanks for the info.

Darin, I've got one of the Poulan 46cc's (2.8ci) sitting in the garage in a chain saw thats ready to trash due to needed external parts. What needs to be done to convert it?

just do a search on poulan and you will come up with tons of info.
just flew my cap with the 46 again today I love this motor.A buddy of mine has a h9 540 with a high dollar ys in his and he is jealous hehehehe.

bn120: Thanks for the imformation on prop size ect. Did you have to do any mods to the Cap for flying with the 46cc Poulan on it? That was 1/4 scale..right? Thanks John

No I just mounted it with the supplied h9 mounts and spun a prop hub for right length.it is the 1/4 cap,
