I have a Picco/ofna .21 engine that is in a Tmaxx. I can't get it to stay running. It finally started after a new glow plug and it runs for a bit and then dies. I think that the tune on it is way off. Does anyone have a manual or at least know the out of the box settings for the high and low speed needles?

Refer to the link below for what should be your engine manual; containing baseline needle settings.

Good luck.

Huge help! Thanks. Previous owner had the main needle at 2 turns out. I manged to get it idling great with it 3 turns out, but it would stall with a touch of the throttle.

Ok, so have you read the instructions and baselined the carb; then run again?

Glowplug and fuel choice can also cause running issues.

What are you using for a glowplug right now? McCoy #8; or #59; or Odonnel 77, 88, or purple sport plugs should get you going.

If it stalls when you touch the throttle, then your low-speed needle may be too rich.

Well, I can't say what plug was in it originally. I bought and installed a O.S. #8. The description for it said it was a medium plug for 1/8 scale offroad engines. As far as fuel I am not sure what the PO used, so I am using Byrons 20%. I will mess with it some more today and post back up.

Well I am still stuck. It starts and idles, and then starts idling really fast after about 20-30 seconds. There are a lot of air bubbles in the tank and the line. There is no telling what is wrong with this thing.
