NTC3 stock AE .12 engine tuning questions

[igorkv]

I have on my NTC3 stock AE .12 engine.
When I start it, it idles OK for a couple of seconds (3-5) and then RPM go high and car starts to move. After running around for some time and warming up it still the same result - it idles ok for couple of secs and then RPMs go up.
Which way should I turn the LSN?

Other thing:
When I hold my car and give it full throttle
I see some fuel coming out of pipe end.
Is my HSN to rich?

Thanks in advance,
Igor

Your low speed needle is way too lean. You need to richen your low speed.

Thanks uncdrock. What about my HSN (fuei coming out of pipe). Is it too rich?

Fuel coming out of the pipe is a good thing while breaking in. There will always be a residue that comes out during the life of the engine. That's the oil from the fuel that lubricates the engine.

After your break-in process, change the plug and retune the car for performance then recheck it for temperature to make sure you're engine isn't overheating. General rule of thumb is to shoot for 220-260 degrees.

Don't forget to retune after you pull the restrictor out of the carb.
