Today, I started it up to run it a bit. It was about 20 degrees outside and right from the start my tuning was WAY messed up. Whenever I would do a half throttle drive by, it would stall and shut off. I brought it inside after 10 minutes of messing with the tuning and decided, maybe if I just reset the needles to factory settings, then retune tommorow when it will be close to 40 degrees out, it will work better. So I reset my needle to factory settings. Do you think this helped me a little by doing this? Will it be easier to retune tommorw no that they are reset?

when you tune for temp, the colder it is, the richer your tune will be. there is no magic formula that I know of, but if it's 20 degree colder than your last run and tune, I would start off richening hsn about a half turn right away and go from there. Putting your needles "back to flush" doesn't reset your engine, if anything, your chasing and wasting fuel to tune properly again. With time and experience, this will all get easier for you... good luck

Did I do anything that i will regret by resetting it? SO tommorow when its warm out, I can tune it and keep it like it is once it is tuned right, then richen it on the cold days and i will be fine?

you didn't do anything besides make more work for yourself. Once it is tuned right, you shouldn't have to do much other than an hour here or there for weather

You won't regret. Anytime when you get lost with your tuning, You should start from flush again. My quote before I overstated. 1/2 turn might be a little much. Some say 1hr etc... When your dealing with big temp swings, an hr isn't gonna be enough. Like I said before, with time and experience, you'll get it. remember to fine tune when the engine is warmed up.

I was just wondering if running a little bit rich is bad for your engine. To me, it makes sense that with no fuel, engine will wear out more because no fuel, lubrication. Although, I think that too rich may not have any negetive effects, just poor performance

running to rich can have negative effects also. very hard on connecting rod because its trying to compress the extra fuel and you cant compress liquid.

Again, I had to reset my needles to stock settings. Last time it did, it took me little to no adjustments to tune it right. The reason I had to do so, was because when I was cleaning it earlier, the compressed gas blew the black thing over the carb slide off. The carburator got all messed up, took me about 3 hours to get it all back together and adjusted. Tommorow it will be about 50 degrees outside, so I think It wont be that hard to tune it

Traxxas is such a pain to tune. Nevers stays consistent.
