needle settings

[MrUnlimited]

Hi everybody,

I took my carb apart of my Picco .67EXR Bluehead and forgot to count the amount of turns

Can somebody tell me what the standard needle settings are?

Mr. Unlimited,

There aren't really any standard needle settings but a

good place to start is at about 4 1/4 turns and adjust it from there. To many variables when setting a needle,

ie pipe length, % of nitro in fuel, humidity, weight of boat,

prop type and size. I find the ultimate pipe length for either the Pico 67 EXR or the CMB Cam Hydro motors is around the 11" mark, + or - 1/8" on mono's and out-rigger hydros, scale hydro's like it around the 11 7/8" to 12 1/4" mark, heavier boat, running an Octura X-series prop.

Thanks,

I'm running 25% nitro (nitro is expensive here in Europe) and a pipe length 0f 12 3/4 inch in mijn 1/8scale hydroplane.

Mr. U, budpilot is telling you right, make the pipe 12 1/8 in. bottom out the needle and turn it out 4 1/2 turns, and definitely up the nitro to 50% will give you a much faster boat and a better throttle response. If nitro is hard to get in Europe,check around to see which clubs make their own fuel or who is the fuel GURU. I race 1/8th scale as well so good luck and keep us posted 8)
