T-Maxx 2.5 Tuning Help

[quadgeek63]

I am a new nitro owner, with zero nitro experience and I am having trouble with my t-maxx 2.5 tuning. I was fouling plugs constantly, so I went back to the suggested settings and went from there. I no longer foul plugs, but it is stalling pretty often now. It seems like right when I start it up, it runs pretty well, starts easy, pulls wheelies, but after 1/2 tank or so it starts bogging out some and then will stall out. Starting is then hard after that, and continuous stalling from low speed. Please, if anybody with experience in nitro cars can help me solve this problem it would be much appreciated. I eagerly await some responses as I would love to get out and drive this thing more often! Thanks in advance.

Right when you start it up it pulls wheelies? That's not right, and it's a sign that your LSN is too lean.
You need to richen the LSN and give the engine some time to warm up before it performs properly at running temp.
Being too lean is also the reason it doesn't want to restart when it stalls. You probably don't use a temp gauge, because if you did, you'd find it was overheated.

ok so i should just richen the lsn like 1/8 turn and go from there? Does that have to do with it bogging out and stalling too then?

On the low end it does. When that's set right, you'll need to adjust the HSN for WOT.

I just ran it around some and it was a little better but not perfect...some stalling and hard starting, but better than before. I should just keep richening it until it never stalls? Also at idle just sitting there, sometimes it "bucks" repeatedly. Does that have to do with idle speed adjustment?
