Revo loading up

[johnbrumbaugh]

My revo when i start it runs until i give it gas then it just stalls, i have to keep starting it over and over until it just goes. i'm not too sure what is causing it to load up. once i get it started i have to rev it up to keep it running. I've gone through about 12 tanks (that includes break in) any one else have an idea what causes that?

Sounds like a fuel mix issue. If you've just finished breaking it in, you may need to lean the HSN and LSN a bit. Start with the high speed needle (HSN). That sounds like the culprit. Turn it 1/8 turn clockwise and then run it for a minute or two to see if it gets better. If not, turn another 1/8 turn and run again. That's the place to start. If it gets worse, then turn the needle the other way and see if it gets better. But it sounds too rich to me.

thats what i was thinking because whenever i give it gas it stalls, and when i start it back up seems to be alot of unburned fuel.

thanks

It sounds like it's very stubborn from the start, then gets a little better. That means it's taking some time to warm up. Not unusual. However, it shouldn't be that stubborn, so it is still too rich.
When you have leaned the HSN, see if it runs better. It should. after a tank, let it cool down completely before you restart. When it's been restarted, let it idle without throttle, and make note of the temp when it doesn't rise any more. Idle temp is also an indicator of overall performance at low end.

thanks i'll try that; your right though when i've started it after a tank not letting it cool it starts fine.
