I have to say i can definately second this notion as the RB engine I have in my buggy right now was a serious PITB to get broken in. So just take ur time on breaking it in, it can definately be frustrating to get it to stay running, but that is just because these engines have such high pinch and compression when brand new that it can if u have to do it that way take a loosening of the glow-plug 1/4 turn to release some of the compression when trying to start it. Just have faith man, things will get better slowly. It just takes time with these RB engines. And good luck with it....

Like everybody on this thread says take your time. Small changes to these motors. Remember to tune after your engine has warmed up 3 min after start up for me. I also have to agree that you might have to check the fitting of the carb. Make sure that the carb base screw is tight and the carb pressed all the way to the base.
You have a very powerful motor! It just takes some time to get used to!

Thanks guys i will try again and just run it and get it nice and warm.

Victor: it was a new engine.

From what people are saying it doesn`t look like 1/2 a gallon through it has been enough.

And one more thing...NEVER tune when the engine is still cold.

Mine was at a little over a gallon before it started getting fast.
