Picco .15
 

Hi,

I got one of the new Picco .15 engines (Dark blue head, sliver crankcase)

Its a rotery carb & I have the main needle 4 1/2 turns out & the low end 2 turns out.

I'm running 16% nitro.

Its a new engine I've run about 3 full tanks in my T-max through the engine.

I cannot seem to get a tune.

The engine on idle 'surges' the revs rise & fall, its a constant rise & fall, very regular.

I know its not a lot of fuel to pass through an engine but after the 2nd tank I had it on my local touring track just to blip it around & heat cycle the engine.

When I gave a little bit of throttle it 'bogged'. As long as I blipped the throttle the truck moved but if I gave it a slight throttle up it would bog.

How many heat cycles should I give this engine 6 - 8?

Has anybody run-in one of these engines and how did you get on?

What glow plugs are you using?


Many Thanks
