Leave the carb at its factory settings. Idle one tank of whatever fuel you plan to use; keep the temps around 200F. Allow the engine to cool completely with the piston at the bottom of the sleeve. Install a fresh plug (hot), then proceed to drive the car, but don't give it full throttle. You should only have to tweak the high-speed needle after a couple of runs. Remember that the engine won't give its full power until after a gallon has gone through it. Use after-run oil (3-in-1 works as well) after every run.

Old Skool,

you seem to have experience with Picco engines.

Here is my question.

On the Trinity site, they state 2 turns out on the low speed needle for the new carb.
The carbs I got are all 5 turns open from the factory.

How do you adjust yours?

stefan;

There should be an instruction manual inside the box with your new engine. This will have the base needle settings for starting your engine for the first few time.

I do NOT recommend 3-in-1 for afterrun. Reason is that 3-in-1 is NOT meant to be burned inside an Engine and could possibly cause deposits to build up over time.

Try some 'Marvel Mystery Oil' instead. 'Marvel' oil is meant to be mixed with fuel and burned in the combustion chamber of an Engine. 4+ years of using 'Marvel' and never a problem with rust or deposits in the engines. You can find it at most Auto parts stores.

stefan;

I only have the Manual for the older stye Carbs (4 bolts on the needle side).

Here is the settings per instructions (old stye carb);

High Speed Needle - 1-1/2 turns out from closed.

Low Speed Needle- 3 to 3-1/2 turns out from closed.

Hope this helps some.

Already done it, its a turbo-plug but i dont think its a picco-original glowplug. Its leaking when engine is running, small bubbles of fuel coming out around the glowplug.

Its like the plug is too long, but i want to make sure i order the right plug and that is why i am asking.

Thanks.

Turbo.

Picco if possible .. they have a slightly different taper than others.

Others will work but you may experience the leaking problem.
