Well I gave this engine Another Shot and I am NOT impressed. If this is what the new OS quality is like, then it isn't worth my money. Fortunately I did not pay money for this engine. Not a fan of OS pumped engines at all. I'll stick with the OS Engines from the 80's and 90's thank you very much. At least then they had not yet lost their way...

Glad to see this run much better than before. Much better run which was great to see. I still think there is some more adjustment to the low speed (lean) as there was still a detectable drop in revs after the glow igniter was removed? Totally agree with the YS comments. Those engines just explode from idle to full power.

I have 2 of these and highly recommend them. The pump system works very well and they definitely suck the tank dry, they run just as well invente. They also run without the muffler. As I said I highly recommend them

your tach hitting the prop made me remember a few years ago,i was running a new magnum fs120. my uncle was looking at the motor and i told him not to stand so close to the prop. well i turned my head for a second,and it happened. he stuck his finger in the front of the prop. found pieces of finger tip on my run

Hello David . I`ve been away from your channel for a while , man am I glad to see you back doing engine videos again . I grew up with my Dad scratch building planes ,covering them with silkspan , and putting k&b green head 40`s in them . I love your archives , I go nuts watching engines run that I`ve had or friends have run in their planes . It can be a real trip down memory lane for me . Great to see you again and you are greatly appreciated by many . Thank you .

Pretty decent run OS engines are usually awesome runners right out of the box, but diaphrgram pumped engines tend to need more time to run in, maybe pump and carb regulator are part of the run in process, once fully broken in they are rock solid reliable thats what i found with pumped OS engines.

Had a friend who had a new in the box os 70 f/s ultimate and had nothing but problems with it . He sent it back to os , they couldn't fix it so they gave him credit on a another different new engine ! That was a Good run , but I'm surprised the tachometer doesn't have wings for I would have thrown it ! Keep up the good work !

Thanks David, I wonder if this engine would run better without muffler. As you know I run this engine on a 1/4 space walker with exact settings that you mentioned and it’s very reliable.

The -155P may be a different engine but when my OS FS 91-Pump was operating OK, it would run without any issues till the tank ran dry. Nowadays I am having problems and I think it has to do with the regulator and/or pump perhaps not working as well as they once did. One other comment. From the sound of the engine, it seemed the propeller was taxing the engine too much. Have you tried a smaller prop or perhaps a 16 in prop with a finer pitch?

Ha! Great vid Dave. Those turnigy tachs are rubbish!! I’ve chased those numbers up and down also. More of a guide then accurate. Anyway ... good to see another run mate. Sounds sweet! (Although Teddy didn’t care for it much !!🐈)
