OS engine from the 80th is just fine piece of work. Thank you for sharing this video. I will run my 61FSR tomorrow because it was so inspiring to see your video. Br from Sweden.

I wish all my engines had a midrange mixture adjustment screw. It would help when trying to fly with zero nitromathane fuel. I hope you are having a great summer!

I'm a fan now. I'm just getting back into R/C. The Engines off of Ebay aren't not Necessarily new when New. So Far I've fixed 2 due to your Help. I'm doing a HP .25 now. Took it a part tonight. Everything seen okay. I watched yout .21 video. Gritty inside. Ordered a $100 worth of Parts. Thanks. Without your help. They'd be nothing more than Paperweights!!! Yep the rusted .25 cleaned up good! Thanks!!!!!!

Most glow engines will run fine on FAI fuel. As I mentioned in the 40 SF video, the tuning range just narrows a bit. So it takes a bit more finesse to get it right.

Another great video Dave! How would compare the 61 FSR to similar engines from the time period? Like the HP 61 Gold Cup, Webra 61 speed and HB 61 PDP.
@dmrcflyr2

I am not certain how I am supposed to answer your question. Compare in what ways? Quality, longevity, max RPM, what? I do not have an HB 61 PDP nor an HP 61 Gold Cup engine. I have had several Webra Speed 61 and they are nowhere close to the same level of quality, fit and finish, ease of use, etc.

i believe the lower screw is the retainer for the idle speed discharge assemble. the upper is for low speed adjustments.

No the 7L carb only has those three controls. The 7M carb has four controls, HSN, Low speed, Mid-range, and throttle stop.

@aileronmodelismo I guess I do not understand making a comment like yours if you are unwilling to justify it and back it up. I ask again, define ‘better’. In your mind what makes an 11” prop on this engine BETTER? If you cannot back it up then your comment is meaningless and has no merit.
