Your engine looks really familiar to me, and the one that I have came out of a Husvarna. . I don't know if there is any thing left in my junk box that could give any additional information except it appears to be a really well built engine for the most part. Mine has a scoured cylinder, and I haven't really worked to diligently on it. I am in the process of getting a Model T ready for the reinactment of the 1909 cros country race that went through here. I don't plan on going with the race, but will be part of the celebration when they get here. I will see if I can gather info on the Husqvarna and pass it on. Flathead

Hi,
To the label was written only Husqvarna, nothing else.To the chain was not written Husqvarna. Cylinder is the same as in ZG45 and those of almost all RC 45cc engines manufactured in China, Bore = 43mm, Stroke = 31mm (same ZG45),has 2 rings on the piston. At Chainsaw crankcase body made with a bath oil for chain.These parts were cut. At Husqvarna is not so. The engine is separated from the rest being fixed with four screws.
The engine is almost identical FTL45 from Hobbycity
Best regards

Hello,
I found a new Chainsaw of the same model of 45cc converted. Everything was just on the outside, the same labels, the carburetor, close the cylinder, piston differ in shape. Surprise is 50cc engine. 45 bore and stroke 31. Put some pictures of the engine block. I got the engine without plastic carcasses.
And I have to work again![:@]

Hi,
Crankcase is ready to cut. While the engine was new, original ignition and crankcase gaskets are damaged. In other engine seems OK. My friend Jimmy put ignition from 45cc engine and started. Continue after cutting.

Hi,
I finally managed to make me a muffler, light and compact, 100g- 0,22lbs, so the final weight of the engine is 1800g- 3,97lbs. I play the muffler is made from air filter housing from an old Mazda 626. Volume is nearly 2 times the capacity of cylindrical engine so it is OK. May need to adjust screws, bushings to do the 2 screws to mount the muffler. Also need to make an intermediate piece between the muffler and engine.

Since I saw your post on this engine, I dug mine out today. Found out that a G23 muffler fit right on. Since the Mag Coils were part of te case, I made a electronic set up with a rare earth magnet in it, and since I was running short or time, I didn't take time to make a Prop adaptor.. I hooked up a C & H set up, and it is a screamer. Didn't run it to long because no cooling shroud, and no RPM test. Now tonight I will try and get a prop adapter cranked out for further tests. I am impressed to date. FLATHEAD

Hello,
now my engine is running very well. Start very easy and never stops in flight. I changed the ignition with Rcexl for 10mm spark plug.
