Webra Speed 61 Run After Ring Replacement

First run after ring replacement. On this run I experiment with a Fox Miracle plug just for the heck of it and it did not perform well. I then switched to an OS #8 plug and things improved dramatically. I used and APC 11x7 prop, the two plugs mentioned , and 5-6% nitro fuel.

Please read the video description and watch the ENTIRE video before offering any comments. There is a progression of things that occur in it. You might notice that never once in this video did I ask for opinions or suggestions.

[@marvinwooster223]

You are not a used car salesman or a politician but really good at glow engine videos , which I really enjoy and have learned a great deal ! Keep up the good work!!!

[@davidfincham5181]

Hi David, you put out some great video’s, always watch them right through. These Webra engines were over engineered to the point they run for years but their carbs were never any good. Over here in the UK most people changed them for OS carbs or anything that allowed them to run.

[@dmrcflyr2]

What OS carbs did you find that would fit the Speed 61 engine?

[@donrichter3523]

Agree about Webra carbs, I only ever had a Speed 61 and Speed 120. While both were strong, I never felt they ran good. I traded them off and never shed a tear about them. Even though Supertigre used some cheaper quality parts, I always found them to run much better and while some disagree, I found their carbs to tune far better AND hold that tune.

Great engine and nice setup. The engine runs very good after replacing the ring. Finding the perfect adjustment is the challenge we have to face. I have got some Webra engines of different sizes, some made in Germany and others made in Austria and most of them are running really smooth but need a good prime at the start, especially the "bigger" ones (61, 91...). Thanks a lot for sharing this very interesting run.

Never change the way you do things David, its a great channel, and I learn something new with every video, its nice to have your library of previous videos to refer to aswell, keep up the brilliant work, and keep well.

[@dmrcflyr2]

Thanks 👍

[@michaelbechard1978]

I've been watching your videos for years and learned a lot. Please keep the videos going. Keep up the great work.

[@SomeGuyInSandy]

It seems to be a nice running engine. The pipe sounds like a good match. Thanks!

[@fredrik-cm4kl]

I say hi from Sweden, great video, I learned great stuff from you m8, always nice to see your video, keep up the great work 👍 😀 and take care.

[@dmrcflyr2]

Thanks, will do!

[@Irvine7214x6apc]

David, the carb needles may have some O-rings in them; given the age of the engine they may be well past their best. If you care, and if you can spare the time, try replacing those -if existent- O-rings. I recently replaced mine in the Irvine 72 and it once again behaves like a brand new engine. Huge difference. Regards Harry

I’ve got 2 Webra Speed 61’s, and 3x Webra Speed 45’s that I’ve restored. Amazing little engines!

[@chrisross7936]

H.S. needle looks correct. I have the same engine but the stub at the outer end of the H.S. has a tightly wound spring with a knurled knob attached for adjusting. Thanks for making these videos! I've gained a lot of knowledge from your channel. Chris

[@dmrcflyr2]

Thank you for the information Chris. The high speed needle on this has a very sharp pointed end and the low speed needle is blunt. Is that what yours are like?

[@chrisross7936]

@@dmrcflyr2 Exactly. H.S. steel and L.S. brass or bronze.

[@PierreMilcent]

Thanks for your contribution.

[@weofnjieofing]

This engine takes a long reach plug so the transition issues may be caused by the shorter OS no8 plug , which can flame out on transition. I’d suggest either an Enya no.3 or OS LC3 plug. I do think this engine would require a longer break in before it gets happy.

[@dmrcflyr2]

An Enya #3 is not a long reach plug. It actually had better transition with the OS #8 than it did with the Fox miracle plug which IS a long reach plug.

[@andreim841]

Legendary engines...

[@clforever1]

Yeah for sure--in the seventie's pattern champ's like Hanno Prettner and Wolfgang Matt had a huge succes with them...there was also a .40 and a .91 variant.

[@matthewturowski8281]

I have a couple of Speed 61's, none of them have a high speed needle like that so you might be right about the needle. But all of mine were bought off the internet, so who knows whether I have factory original carbs. I have a few with the dynamix carbs which run really well, and another with a very long and flexible HS needle and that one works good. One came with a perry carb, that would never lean out enough to get max rpm, as an experiment I bought a brand new Perry carb, same result. Webra's are one of my favorite engines in that size.

[@dmrcflyr2]

If I can find a Super Tigre crab to fit this engine I will. They are great carbs. Thanks for the information! he high speed needle on this has a very sharp pointed end and the low speed needle is blunt. Is that what yours are like?

[@donrichter3523]

Agreed. Some don’t like them, but I always seemed to have good luck with ST carbs, and the engines as well. Only thing I disliked about the ST engines were the cheap cast prop hubs. I wore the nubs off numerous times and had to replace. Fortunately, ST parts were usually very inexpensive, so I didn’t mind too much.

[@clforever1]

David,you're missing the spring part of the high speed needle-that's normally placed over the pointed end of the H.S. needle ,look it up,there's pictures and videoclips all over the internet of that engine-also,there's two carbs for that engine,one is the flatslide DYNAMIX carb, the other is the normal drum-style valve carb like your engine has.

[@dmrcflyr2]

Understood but these parts are not available

[@yanicks9040]

I just remembered, how is your hand after the time you got hit by the prop (I think?) in one of the last videos? I hope it was not anything serious

[@dmrcflyr2]

That was the Moki 180 video. Just fine thank you.
