Learned to fly RC with a 40FP in the 90s. Great memories!
I just rebuilt the same (even made my own gasket) a couple tips for US viewers: gasket is 120lb card stock for the exact original gasket thickness, for the exhaust sealant I used "permatex copper" which was easy to do and worked a charm. I used jewelers "polish pads" to polish all the surfaces leaving the cyl insert and piston as they were. A little fiddly on the test stand but she did fire up and ran beautifully for break in. If I can do it, so can you! Thanks Mark!
Mark --- Will watch your 34 videos on engines - will keep my question ( s ) to the end video you may answer them by then. and maybe other viewers will have my answers by the end video.
Really enjoy you explaining the break down and the reassembly ----- Rodney
Thank you , pleased you like the videos
Fun watching. Those engines are virtually FOREVER when run with pure castor oil. Cheers.
Thank you!
Great results! Looks good, sounds good. Idles good. Transition is good. Perfect amount of smoke when running high RPMs. Good video. Thanks for the post.
Pleased you liked the video, thanks for the comment
Runs really well! 😊
Great job, looks and runs awesome
Thanks 👍
Great job nice rebuild enjoyed that , she sounds and looks like it's a new 1 🤙🤙
Thanks 👍
My first RC engine, I bought one in USA as a long time ago and now I got it again and will flight a small plane after 10 years. I love that engine too! But I still not achieve the better adjust like you... It runs at maximum RPM and after 3 minutes stop. Good video, thanks...
Thanks for the comment, pleased you liked the video
Nice well explained video Mark. Im about to restore one myself, keep up the good work 😊
Thank you very much for the kind comment, always appreciated. Hope your restoration goes well 😀
🙏❤️
Great video again, will do the same with my own OS 40.😁
Go for it! Thanks for the comment
Great stuff, very good tips, great execution and very well explained, hope to see more of this excellent content soon! Cheers mate...
Thank you very much, really appreciate the comment, glad you enjoyed the video. 😀
My first engine on my Goldberg falcon 56....still got it and still runs since 1991
I was watching the video and I heard the "pop" when you flipped the prop and I knew the engine was good. There is a certain sound that says I am a broken in engine with lots of life left in me
Thanks for the info with great content.
Thanks very much, really appreciate the comment, pleased you liked the video
@@MarkRobinson555 I do have a question now that I have my pedal in front of me.
Speaking about the adjustment screw, how far should it be in relation to the carbon rod?
Mine had the usual issue of not wanting to spin the motor, then all of the sudden it comes to life deep into the pedal push. So I adjusted the screw in to about half way, and noticed it is still not making a connection to the carbon.
Should it be touching the carbon? Or does it not matter?
Thanks again
Great little engine.
Yes, it ran lovely
thanks for your time and video,I was hopping you would show us the position of the ports in the cyclinder when you are putting it together I have a mark on the cyclinder but not on the block so when I took it apart did not pay attention on the ports positions.now it does not start mabe beacause I have the cycinder on the wrong position ??? thanks for you time again
Thank you for the kind comment about the video, pleased you like it. The exhaust side of the cylinder will have carbon on it from the gasses, and the two ports will be of different sizes, the exhaust is often larger, but theses should line up correctly in size with the crankcase casting - hope that helps, good luck with getting the engine running again
Changed my silencer bolts to s/s Allen key/hex drive bolts
Was common at the 90es , alongside with ballbearing engines..
Great video as always, loving your recet stuff! Interested in picking up an ic model, I only fly electric at the moment. Have no real experience with IC your videos are great but do you know of a good resource/getting started guide to running and maintenance? Thanks
Hi there thanks for the comment, I found with IC the more you use them and run them in test stands, playing with the tuning and reading about how to tune them, the more I learned, but also talking to people and finding someone, who's judgement you trust to talk to for advice. Good luck, they are great to use, I enjoy the IC side as much as the flying it's self.
Oliver. As Mark said. However, if you are in the market for one, get yourself a new engine, you can't go wrong with an OS or an Enya, ( my personal favourite make). I say new as you can follow makers instructions re fuel and prop size plus you know it's not on its way out.. Get one and enjoy!
Nice running engine. I like the 25 and 40 FP in my smaller float planes. If I happen to have a mishap and dunk the engine, I don't have to worry about ball bearings rusting.
Did you Put a new O ring on when you put the carb back on? It looked like the original O ring was still on the bench.
Hi, thanks for the comment, yes it needed a new O ring, old one had gone stiff and brittle, in my mind its an easy win as they are cheap and easy to obtain, and can make a big difference.
Hi there, can I ask you is that a Black and Decker workmate you have there? I've just bought engine test stand and had thought about getting a workmate to clamp it too. Thanks .
Yes it is, works really well with no issues, lovely and solid
The direction of the fuel inlet was bothering me right up to the time I saw the motor on the test stand... whew! Lol
What’s the normal operating rpm range for this engine or any other engines
The normal range is usually around 9 - 16,000 rpm, but the rpm is highly dependant on the fuel and prop used
Mark how have you made your throttle control on your test stand,you appear to use the same on all engines?
Yes, same on all engines, its just a clevis on the end of a threaded rod, which is held loosely/ friction fit, on the wooden throttle control leaver. Its loose because there needs to be some movement as the wooden leaver moves through an arch, its not perfect, but works ok.
Mark what do you use for making replacement gaskets I just got a Enya 09 need to make new 1 thanks enjoy ya vids mate 🤙🤙
Great engines, Enya - I use automotive gaskets paper, which is readily available on ebay or from automotive shops etc. glad you like the vid, thanks for the comment
@@MarkRobinson555 thanks mate look forward to seeing more of your vids 🤙

@@MarkRobinson555 Nice 1 mark just watched that vid will be making sum up today thanks
Good morning Mark. As you said, what a great little engine, it looks almost new. Do you think my wife would let me use her ultra sonic cleaner. Nice one. 👍
Hi there Terry, good morning. Yes, it ran really lovely. Sure you could use your wifes cleaner, just dont leave it dirty!!!! hahahaha - good luck
Hi dave nice vid ,i have a os fp series 35 its nice clean great compression but i get it started it runs ,but once glow ignited comes off it just splutters and dies any advice thanks
Have you tried a different glow plug, sounds like the one you have may be an issue, or you have it very rich - Its Mark! 😉
@@MarkRobinson555 sorry mark dont know what i waa thinking calling ya dave 🙄will try that today thanks
@@homienat3374 hahaha, no worries, easy done. Good luck with the engine 😉
Hey mark happy to report you were right ,changed the plug ,lessend the the high speed she is nearly there thanks mate 🤙🤙
Hi Mark need help with an old OS 29, made in Japan. Know nothing about it but got one. Used to he my dad's. I want to make it running in his remembrance. Can you help
I would suggest that you find a model club close to where you live, and I am sure someone will be able to help and advise you local
Hi Robert - My father passed about 13 years ago and I got his model plane from my mom this past weekend. I took the engine apart to clean it and noticed the seals need to be replaced. I believe you linked a gasket making video in the description of this video however when I click the link it was a dead end. Could you repost or re-direct me to that vid? Thanks!
Sorry, fixed the link, thanks for letting me know it didn't work, Mark
ruclips.net/video/VWzPTWVGEOI/видео.html
could you do a video on how to build it out of the box
sorry I don't understand the question
Mine came without head gasket. Is that okay??
I think it would probably benefit from a gasket, you could make one out of some heavy aluminium foil. However, if not loosing compression maybe you can get away without one
Hello Mark, do you know what the lifespan is for a glow engine?
Well I guess that is a how long is a piece of string question, I have certainly never worn one out, if treated right seem to run for ever, but life will depend on so many factors, like fuel mixture, % nitro and oil, prop size, hence how fast you run them, use of after run oil, correct cooling, ie not getting really hot in a cowl, the make and model of the engine and of the course the ultimate, driving them into the ground at high speed is a little detrimental! Hope that helps
@@MarkRobinson555 Thanks Mark, you are right and Mary Chrismas and a good Newyear.
Thank you, hope you have a good Christmas and New Year as well 😀
