is this engine running rich, or just dying?

[tmd]

i have a problem with my car. it would start fine, but i seems like it want to move forward for a couple of second after i every start. seconds after it wants to move forward, it stops and normal again. also i have to press the throttle slowly, otherwise it would die, my friend told me that this is running rich which is safe, but i dont see a lot of smoke at WOT, just some smoke. is this normal? thanks. btw, i have RS4 RTR3, with .15FE engine in it. thanks

sounds to me it is running lean, not rich. also, you could have a bad clutch, might want to remove it and inspect the springs for wear.

but the car never get hot. also i saw fuel coming out of the exhaust. the clutch is brand new

First ..Have you set it to factory before running it again? I talked to NA about this Mill before and I found out my problem was the ISS (Idle Set Screw) . You also may be having an issue with the carb opening . Close the HSN but be careful as overtightening it can result in torn O-rings. when you close it then bring it out 3 1/2 turns. I know the manual says 3 but try this first. Then put your throttle trim setting on your radio to the middle. From here I hope NA or someone can take over cuz it gets a little hazy sorry

Try lowering the idle a bit.
Then you can play with the other needles.

There is only ONE NEEDLE. Try out what I said. As you can play with the ISS all you want and still have the problem . I experienced the EXACT same problem. I was trying to keep the engine running by using my throttle trim. TRY OUT WHAT I SAID.
