ORIGINAL: mojo-maxx I agree with you Dale, a main part of the appeal for me is the fact its a gas engine and learning how to work with it. Which leads me to a question you could probably help me with. I have my T-Maxx broken in (I followed the break-in procedure to the best of my ability) but in the process I messed around with the idle and the low speed setting on the carb. One of the things I'm having problems with is getting a good idle speed. When its high enough to keep from stalling, it keeps trying to creep forward, when I lower it to keep from "creeping" it usually stalls (especially if I brake). Also, after I have been running it for awhile and it stalls, I sometimes have trouble getting it started again. Any suggestions? Thanks. It will usually idle fast and temps will creap up if the LSN is lean... Doesn't sound like that is the problem. The problem you are having is a rich LSN. I bet your truck 'bogs' when you first hit the throttle, right? Warm the truck up by running it up and down the street. Leaving the truck running, start leaning your LSN 1/8 turn at a time (no more then that- it is a sensitive needle). Your throttle response will start to get a LOT better, and it will idle better. Now, repeat this step until you get GREAT takeoff and a good steady idle. Finally, run it up and down one more time. Now pinch the fuel supply line to the carb. It should bog and die after 2 seconds. If it dies instantly, you are too lean. Richen it up 1/8 needle, and you probably have a good setting there. If the motor shuts off around 2 seconds, your LSN is perfect! It will coincide with the performance, because you will get GREAT take offs. Now as far as the idle, I keep the receiver 'off', and start the truck (make sure throttle servo is in center position, and the slide valve is closed). Put the truck on the ground. SLOWLY increase the idle until the truck starts to want to go foward on it's own, and then back it down until it sits still. I don't do this with the receiver on, because then you are fighting the servo. Don't let it get away from you, and keep the remote handy in case you need to control the truck for any reason. Voila, LSN and idle.
