I was given another "victim". This is a Toro engine that appears to be in excellent shape. Very nice castings like Echo or Stihl so I assume it is older. I have looked on the web and at several garden shops but no one knows what this is. Looks to be about 40cc or so but I would like to know a model number or something about it as I may need a part or two when I get into it. Maybe someone knows who actually made engines for Toro in the past. Thanks in advance.

that looks an awful lot like the two Green Machine weedie's I have and the one Stihl FS78 or whatever it is, and with the research I did on the Stihl it was a 25, and since the green machine weedies look the same (down to the barrel style carb and the spark plug position) I'd assume they're 25's too. I haven't gotten the green machines going as both have either a broken or missing fuel tank, and the stihl only runs if you hold the primer button down... (has brand new carb kit).

I haven't torn into the green machines (have $5 into the two...) but the Stihl has points ignition... if you pull off the pull starter you will probably see the parts as the front just has the fan on it

I made a prop hub for a engine simular to it...20cc or less...real nice carb. It ran nice, but was a little heavy. Capt,n

Thanks for the replies guys. Just found it on the web. It is a TC 5000. Made in the 1980's. Engine is made by Mitsubishi for Toro and it is 33cc. My son will strip it tomorrow and weigh it before trimming. Very nice piece and I hope it isn't too heavy. We will see.

Tim....if that is a 33cc engine...you got a good one. The Mitsubishi I worked on was smaller, but very high quality. I am sure you will like it. Capt,n

Love that mini mikuni carb

Terry, different system with some sort of a plunger or slide in it that the throttle cable attaches to. No way I can see to use it in a plane. But I have a nice WT that will fill the need and of course a CH ignition. I may mess with the mag system for grins. Still amazed at the quality of the castings and all the metal parts as opposed to the plastic today. Only plastic I can see on the surface is the fuel tank.

Tim...On that Mikuni Carb, maybe you could rplace the cable with braided fish line and if the you think the slide spring is to strong....cut it shorter or replace with weaker one. What is the venturi size of the carb? Thanks Capt,n

Looks to be 11mm maybe. My son called me and told me he finished stripping it and it weighed in at 2 pounds 6 ounces. Still need to trim the housing. So I figure it will be around 2.5 pounds or so ready to fly on EI.

Well here it is all trimmed down and ready for the mill. Some time anyway. Final weight is 35.7 ounces sans muffler, hub, carb, and spacer. Should be well under 3 pounds ready to go. Maybe I can figure a way to put the ignition in the back. A huge bell back there. Or maybe I can do it like I always do. We will see.

ok, back from playing in the garage...

the two green machines I have are actually Xenoah, the two minutes I spent looking on google/ebay says they made a decent amount of snowmobile engines, but didn't dig all that far... the plugs stick straight out the jug instead of at an angle, twin pinned ring domed piston, same or different model of similar carb as the stihl and toro engines, points ignition, counterweight on both sides of the rod, cast iron or steel connecting rod (floating needle bearings),

the one you have looks like the Stihl trimmer I have though so they're probably made by Mitsubishi...
