Pop's... what do you run for a exhaust manifold? The Picco exhaust is smaller than the NovaRossi type motors and most pipes I find are for the larger style.
I run the Picco (not Trinity) brand manifolds. Otherwise I can't keep Header Gaskets in longer than one race day and the tubing diameter is larger. These Engines really like the NR #51603 Pipe.


I have always removed the THIN shim in my Picco .12's with 30% and get at least 9+ gallons through them. The last one lasted about 22 months, so durability has never been an issue.

Shim count is not as important as "actual deck height" . Take a piece of small soft solder and bend the end so it will go into the glow plug hole then rotate the piston past TDC with the solder facing the carb. You should have at least .006" per 10% of nitro as a rule of thumb when measured with a caliper or micrometer.
Ex.: .006" X 3 (30% nitro)= .018" min. ( .021" is better, especially in hot climates)

Hope this helps!

Default Checking Deck Height


The solder method works very well and tells you EXACTLY what the deck height actually is without disassembling the engine.
Just make sure not to use anything larger than 1/16" in Dia.


I bought mine locally, but you might try 'Nitro House' online. They really have a great selection of Engines, accessories and parts, at reasonable prices. I bought a spare Piston and sleeve for my 7 port for about $60-$65 (Trinity wants $90+ for the 3 port).
