I have one gallon of fuel run through my raptor titan with an os 50 hyper and jk hatori pipe.

the damn thing ran great for the full first gallon but now wants to start and stall all the time.
I tried a new glow plug,new fuel tank and all new fuel tubing.

If i do get it to start and try to rev it up it free rev,s like the engine is running backwards. (kind of like it is too rich)

I pulled the engine out and chcked it all out and see no problems at all,I ran it rich breaking it in a few months ago.

I have had so many hyper 50 engines and have never had this problem before,really pissing me off!

I did just open a 2 year old gallon of magnum fuel that was never opened,I wonder if i could have a bad gallon of fuel? ran great until i just opened up this gallon of fuel.

Fuel could be bad, you could have crap in your carb also. I'd clean the carb and try some fresh fuel without doing anything else first.

RichL.
It just may be running in reverse, as it is the only way it would rev up and not turn the rotor. In addition it is also going lean, not rich. That would possible be like Skalug posted. I would not recommend messing with the carb, and would go straight for a fresh jug of fuel first. Alcohol fuel absorbs moisture easily,and I have read it will go through the plastic jug. Anyway with water in the fuel, you can never get a needle setting. You would lean it out, and in the air it will either go rich or leaner and quit. I have disposed of quite a bit of fuel because of moisture in the fuel. I hope that is all that is wrong and you get it running well.Oh and you need to store your fuel in a very dry place,not in a damp basement or garage.

Hey Rich,

Read the post about the OS 50. I would try different fuel, change the plug and let 'er rip.

I run cool power and it's working great for me.

Old fuel can cause issues like that

I bought some new magnum fuel at ircha,took the needle out and cleaned the carb.
still does the same thing.

today i found that if you keep the throttle above 1/4 it will stay running.

tried to spin the main gear and something is binding bad,seemslike something in the clutch bell.

If you turn the starter shaft just a little the binding goes away.
