OFNA Engine Trouble
 

I am still fairly new to this hobby and I have ben having some trouble with getting my OFNA force 25 engine started. The engine was broken in properly.

So here is the problem. It is a bump start. Once it gets started it will idle really nice then when I go to rev the engine, it stalls. Then I finally get it going able to rev on bump box. As soon as I put it on the ground it stalls again when I give it gas.

Could it be the idle setting?
The low end?
The High end?

Please help.

Have you checked your plug ? I've seen engines sit and idle but once they get a shot of fuel they die due to a bad plug. Especially if you have been running it rich for break-in.

Can the truck idle on the ground? Or do the tires have to be in the air? If the truck dies as soon as you put the vehicle on the ground and it can't idle while on the ground check the clutch. Something could have broke in the clutch. The reason I am asking is because you said once you put it on the ground it dies, which would be at first guess a clutch problem. If it idles on the ground though this is not the problem. What I would do is go back to factory settings on the car (Maybe a touch leaner) and adjust your tune from there.
