Hi,

The motor stutters when I pull the trigger all the way. If I pull REALLY slowly it seems to be fine and it actually achieves its top speed. So, if it's going pretty slow and I pull all the way it stutters; if I hold it there, it stalls after a few stutters.

I tried leaning and richening, but nothing seemed to fix it. (I only played around with the HSN).

This is on a tmaxx 3.3 by the way.

Please help!

Thanks.

It's called a 'lean bog' and means the the HSN is too lean. When you peg the throttle it's so lean it starves of fuel. Richen it up a few hours and retune from there.

Oh, ok thanks. What do you mean by a few hours? It takes that long to fix it?

No, sorry.

When tuning nitro engines people refer to needle adjustments in "hours". Basically, envision the needle like a clock face and only make 1 hour adjustments at a time. However, in your case you should go a little more, like about 3 or so I would guess. So if when looking at the slot on the needle it's straight up and down (pointing to 12 & 6 on a clock), unscrew it until it's pointing to about 9 & 3. I hope that makes more sence and isn't too confusing.

I actually richened it up a lot and then started to lean it out, but it didn't really help. Could I have an air leak? (hopefully not); I don't think so because I can get it up to full speed when I'm not suddenly pulling on the trigger, and am pulling it slowly.

I thought it might be a radio glitch but I don't think so either, because I would assume it would stop after a few seconds, but the stuttering is constant for like 7 seconds until it stalls.

My idle is good by the way.

what plug are you running???? if its a cold go to a med., if its a med. go to a hot...and richen up the HSN then start the lean out process again...this might help, good luck
