1946 Super Cyclone .604 (10cc) Vintage Spark Ignition Engine

An American Super Super Cyclone .604 Cu in (10cc) spark ignition engine. This version of the engine was, the GR series, were produced in late 1946 until around 1950 I believe. The engine is run with a Champion V spark plug and Coleman fuel, a petroleum fuel, similar to White Gas and SAE 50 oil, in a mix of 3:1, respectively.

I have one of these and I just can't get over how good they look

[@MarkRobinson555]

Hahaha, absolutely!

[@marshallgreen7815]

I loved this. I have one from my father. He was multi-champion in Canada around that time of the engine.

[@MarkRobinson555]

Glad you liked it, they are great engines, sounds like you have some good memories of your father 😀

[@jacquikowalewsky7691]

I inherited one these from my late father, remember him bench running it when I was a child in the '60s. Also have a green top Taplin twin and DC tornado twin. Not really sure what to do with them as my children are not interested. Do not want to throw them in the skip, thought about mounting on wooden stands and offering to a museum.

[@robertcrook5849]

Great sounding engine. Look forward to seeing this great engine on a nice vintage airplane.

[@MarkRobinson555]

Thank you, yes can't wait to get this in a plane, and I have just the right one in mind! Gladiator!

[@robertcrook5849]

@@MarkRobinson555 Are you doing a build series on gladiator.

[@MarkRobinson555]

I am hoping to, at this engine would be just right for it. I have the plans, but there are a number of things I need to get done first 😀

[@terrymillard9255]

Now that brought back memories. My dad used to fly those. Had one in a scratch built Firebird from the 1939 AMA year book

[@MarkRobinson555]

Pleased you enjoy it 😀

[@jimkraft9445]

Nice video. I fly a couple of them. Two on control line planes, and one on an old free flight converted to R/C. They are fairly light weight engines for that time, compared to many others. I have been using stove fuel mixed with Walmart Super Tech 2 stroke non detergent oil 3 to1. It runs cooler and cleaner than anything I have tried. I have been running it for several years with seemingly no wear issues at all.

[@MarkRobinson555]

Thanks for the info!

[@at0054]

Hello Sir , Excellent engine, please, could you show your next video about the connection cdi and what voltage for this Super cyclone 604 engine.Thanks.

[@mikebyrne3682]

fantastic, what a lovely engine

[@MarkRobinson555]

Thanks very much 😀

[@MarkCroucherRC4fun]

Sounds great, love to see it in a nice vintage model, full power straight up.... Thermal hunting glide.

[@MarkRobinson555]

Yes, absolutely, and I have just the model in mind, the Gladiator!

[@wrxs1781]

Good video Mark, very smooth at the lower RPM's.

[@MarkRobinson555]

Yes, i was really impressed how nice it ran, can't wait to get it in the sky!

[@collinmccallum]

very cool

[@MarkRobinson555]

Thanks 😀

[@johncaldwell-wq1hp]

What a fantastic Engine,--Mark-can you get these running on a "glow-plug"-instead of a "plug & coil"-set up ??

[@MarkRobinson555]

Yes you can

[@Tom-wl9sx]

Great engine. Have an Ohlson and Rice 60 that I'll have to try. Have you got a plane to put it in?

[@MarkRobinson555]

Thanks, pleased you enjoyed the video, the O&R 60 is another great one, bee good to see that running! I would like to get my engine in a 1941 Gladiator, but we will have to see 😀

[@garymucher4082]

Interesting little engine. It is the fisrt I've seen with the exhaust on the left (right, depending your POV) side. Using typical petro fuel(s), It would be cheap to run compared to todays 2 cycle model engines...

[@RyanNX211]

It’s reversible

[@MarkRobinson555]

Quite a common occurrence to have the exhaust on the left with this old spark ignition engines from the late 1940's

[@CliffHarveyRCPlanes]

This is the engine shown on my current build plan Mark, that's the Mercury IV, sounds fantastic, perhaps I need to fit a sound card to go with the electric motor?

[@MarkRobinson555]

No! Get a real engine! Go for it Cliff, go vintage!

[@jamesal0]

Hi Mark I know nothing about these motors. what it the front leaver - throttle ? What is all the linkage attached to this leaver. The next leaver I get, that is mixture. It's not nitro ? Just 2T ? Then how does the ignition work, does it have some sort of pickup like a lawn mower and have a spark box /cdi/coil . in 46 they they didn't have RC transceivers and servo's, so what was it used with ? string hand lines

[@MarkRobinson555]

Hi James, the leaver advances and retards the ignition, which affects the speed of the engine. No throttle. The run on a petroleum & oil mix. The ignition system is just like any other two stroke bike, lawn mower etc, but smaller and lighter. Your correct, no RC in the 1940's so they were free flight or control line. These days we can use them with RC. Hope that helps 😀

[@jamesal0]

Thank you Mark, very interesting they controlled rpm with ignition advance/retard. I would love to see the advance / retard mechanism and pickup pulled apart. Your youtube on cam timing 4T motor was very interesting too

[@stuarthouston5488]

Hi Mark. What do you use for your coil and condensor on these engines ? I have a bantam 19 like the sort in your diamond demon that I would like to get running so was wondering what / where you get the old school items to get it running

[@MarkRobinson555]

Hi there, the Bantam 19 is a lovely engine, runs well. I don't use a condenser, I use an electronic ignition system designed for old sparkies, its kinder to the contact breakers and more consistent. I get my coil, plugs and ignition system from Larry Davidson in the US, this is his website, hope that helps and good luck with the Bantam 😀 modelflight.com/product-category/engine-parts/

[@MrStratbat]

Great video dude..well done

[@MarkRobinson555]

Glad you liked it, thanks for the comment 😀

[@terryblackman6217]

What a beautiful motor. I love the sound of spark ignition engines, that crackling sound. We're you running the motor using electronic ignition or condenser ? Lovely find Mark.

[@MarkRobinson555]

Good morning Terry, totally agree about the sound, It is such a lovely engine to run. I use a electronic switching circuit connected to the points, much kinder to the contacts and seems to work well. There are more spark ignition engines to come! So pleased you like them 😀

[@terryblackman6217]

I still think that you have been bitten by the vintage bug. Thank you for sharing collection with us. Terry

[@MarkRobinson555]

Hahahaha, yes, you may be right! Need to get a good spark ignition hauled plane in the air soon!

[@andrewind37]

I have the same engine with a twin spark.Can you give me an advice about electronic switching circuit for this engine and the brand of it?

[@RyanNX211]

Be careful not to over tighten the timer; they’re quite fragile compared to the Anderson. And, any alcohol in the fuel will eventually destroy that pristine tank.

[@MarkRobinson555]

Thanks for the advice, always appreciated. One of the reasons I use the Colmans fuel is to save the tank, thanks again 😀

[@nerd1000ify]

One thing to watch out for with Coleman fuel, its octane rating is only 60 or so, and 2 stroke oil has an octane of 0 (more or less) so with 4:1 premix it could go as low as 48. Depending on compression ratio you might be at risk of knocking running on it.
