sorry forgot this too
Set on the ground and run around for 3-4 tanks without making any needle adjustments. Says to blip throttle to avoid speeding too much time in one rpm range.
---->Blip means a quick throttle or slowly run it up and release?
Allow to cool between tanks.

you got it pretty much covered bud. i don't own a picco but i used this method on my axial and it still runs really well. and when cooling remember that the piston needs to be at bdc. you can put a paint marking using high heat paint on your flywheel and block to match up to when it is cooling.

Depending on the "PINCH" at TDC you could get away with idling 2 tanks maybe, but give it little blurps here and there to clean the engine out, you don't want it puking out fuel and having the mill bung up with fuel..

But it depends, heat cycle is a deff get her up to 130° F with a blow dryer and it will start rite up..

Then you could set it on the ground and maybe 1/4 throttle for a few tanks then let it cool at BDC then 1/2 throttle for a few tanks let it cool then W.O.T throttle burps maybe .5 seconds..

Then again the Picco is probably different then the K when you first get it, like the pinch and all..

 

[redneck]

is it right to have it very gutless is very slow at the wot blurps

 

[MikeK1981]

Yes it will be gutless because it is so rich. When you blip the throttle it is really loading the motor with fuel and that makes it seem sluggish.

 

[Purenitro]

Make sure your temps are over 200F, lean it out if you have too, running very rich is harder on it then running with a slight tune on it.

 

[redneck]

ok will make sure the temps yesterday where about 220-240 is that good also preheated

 

[Purenitro]

220-240 is fine, I wouldn't try to get that hot with a heat gun, 150-180 is fine for pre-heat.

 

[redneck]

i heat it too 135 ish

 

[Purenitro]

That's fine too.

 

[redneck]

can i take the silver thingy out

 

[redneck]

of the carb

 

[Purenitro]

Not the best idea, it helps with air flow.
