Default O.S. Help

I have an O.S. .12 CV-X engine in my Hpi NMT. I havent run the thing in like 4 months. I tried to start it up the other day but it wouldnt. I tried and tried and tried. I took the glow plug out and tested it. Its just fine. But idk if i messed up the settings i had before on the carb. Does nitro fuel ever expire? If anyone can help me, thanks so much

Yes nitro fuel can go bad after being improperly stored. But i am betting the problem is that you left fuel in the tank or in the fuel lines the last time you ran it. Now that fuel has gelled up in your engine. Remove the motor, disassemble it, thoroughly clean the insides with your cleaner of choice. (Motor spray, nitro cleaner, alcohol) whatever you happen to have. Then remove the fuel tank and use nail polish remover, or laquer thinner and pour some in it. Let it soak over night. Change all your fuel tubing and if you are running one put a new filter on it. Reset the needles to factory settings and you should be good to go again.

The cv-x and cv-r motors are bullet proof. They last forever. If anything goes out in them its usaully the bearings. Now i cant speak for the v-spec or vg series motors but i have heard they dont last long. I have never used one though so i dont know. I have owned a bunch of cv-rs and cv-xs and they are as tough as they come.
