SPARKY333, As suggested we all in this thread should try to help you with your poor running 91fx. YA just dont know how to tune a engine!! You and thousands of VETERAN RCERS.Had one myself in a king kobra.Different plugs,props,tanks and line,needle valves AND LOCATION,fuel,engine switched to different planes,mufflers,removal of cowl,all did not help.I think you and I should go back to the basics as well as ALL THE OTHER THOUSANDS.BY GOLLY its the great OS and it has to be stupid rcers. BY FAR this is one of the most complained about engine ever.Remember when OS engines were peeling. It WAS SUGGESTED THAT IT WAS THE FUEL,or cowls creating over heating,or not enough castor.Sparky just think how all your other engines run like crap! Its because you dont know how to tune dude. Buy a jett 90 end of story. One engine that IS worth the money. PS. anybody who wants to buy my 91 I would be glad to sell it to them . KELLDOG
It is easy to get frustrated and then lose faith in your own abilities. A reminder from friends can sometimes bring thoughts forward that lead to solutions.
I've had a couple of bad OS engines over the years. Engines with known problems, so I'm not one to say that it is impossible that the problem isn't the engine. Especially since Mr. Ogawa has passed on and the business is being run by others with an obviously different philosophy. However, occasionally OS restores my faith in their abilities by producing an engine such as the OS.46AX. I have heard nothing but praise for that engine.
Sometimes just the repeating of the litany of engine failure modes is enough to jog the mental processes into being productive. Some folks shouldn't be so sensitive when others are simply trying to help. Especially when said "others" are not familiar with the forum's inhabitants' skill level.
