Thanks.
Supposedly the black LSN can be ordered from somewhere, wish I could tell ya where, but I did something a tad more radical to fix mine. I'd do a search here with the key words being "black needle picco and outlaw". --edit-- did the search myself here's a few links:
This is what happened to me,

Here's the important link in that thread to the black/silver needle problem:

The place to get the black needle:
www.nitrohouse.com
Go here:
http://www.nitrohouse.com/picco_26_parts_list.htm and look for a part number 51425. It's a $7 part.
If you look at the LSN, it'll either be shiny silver or matte black on the end (all over if you pull it out). The silver one had (I believe) a shorter taper than the black one. What this does is make the mid range real rich, so much so that it kills the engine when it's around 50% throttle. The black one has a longer taper. therefore more needle is still in the venturi at 50% throttle and thus leans the midrange out (more than the silver one) and the engine runs right.
What I did was frankenstein my carb. I took the barrel from my old 21BB carb, extended the idle stop screw channel and used that. It fits perfect, but dremel tooling the channel was kind of a pain. The upside of this approach is that it was free, the downside was that it was a pain in the ass to do. I wouldn't try the first approach that I did in the first link above, the 21BB carb wouldn't stay seated properly.
If you try the Frankencarb approach, I can help out, but remember, it'll make the slider useless in the 21BB crankcase once you modify it like I did. So if the engine still has life in it, I'd just order the needle from nitrohouse.

i haven't changed to the silver to see if the tank was the whole problem.
Don't, it's the wrong one for the outlaw. It's not leaning, it's flooding at half throttle with the silver needle.

If you have any tips on breaking the engine in I would like to hear them.
you like the rpm spur gear. I have the same one, is the gear ratio good when using the picco?
Loosen the glow plug a bit if it's hard to pull start. Mine was pretty tight when it was new. Take your time breaking it in. Burn good fuel, and once it's broken in change up to a cold plug. I run Duratrax Gold racing plugs and have been pleased. Hobby Town should stock them.
The RRP metal spur simple rocks. So far I have had no problems with it, and have not encountered any RF interference running that spur (though I am running a 75Mhz FM radio and not the stock one).
The 52 tooth spur and a 16t clutch bell have done me right on that engine. The top end speed is pretty fast, yet it still has alot of low end punch. It's too much for the 21BB, but the 26 makes out fine. I'd like to try the 47t spur sometime just to see what it would do.
