Leaking Exhaust

[bigredz71]

My exhaust spits out unburnt fuel, is that normal? i could have it running stationary for maybe 10sec. and it will leave a puddle.

Is this still being broke in? During Break in the engine is set normally rich to allow more lubrication of the internal parts.

I beleive is just running a lil rich

My lhb broke it in and I'm on probally the 15th tank. It runs great, do i need to adjust the low speed or high speed screw to lean it out a little?

Thanks

Since no one replied, turn the high speed needle (biggest one) to right I believe. Always keep checking temperature, keep between 250-270. If there's not a smoke trail then you've gone too far!

If it's running good, leave it as it is. Most fuel has a synthetic/castor oil blend. Castor oil doesn't burn very well, it just lubes well. It also leaves a heavy varnish inside the engine over time which is why most fuel makers for land vehicles use a mix of synth/castor (I believe).

A light spray of oil when running is fine. If it sits for 20 seconds idling, the crank case loads up with fuel and causes a puddle as well.

Any idea what the temps at the glowplug are? If it's running between 200F and 260F during normal running, it's fine as it is. Just messy.

I am with Olds here .....if it aint broke......take caution in trying to fix it. Nitro is messy when done right.......

I will have to agree with both Olds and Talon. They're the ones I listened to when I was really new.
