picco tune engine
#16
Sounds a little weird but it is true. A lot of people have tuning problem and glow plug failures (on Picco engines) because the thickness of shims is not correct.
Therefore, if cannot find a correct setting on carburetor and plugs, think about the shims and it does help.
Actually 0.3mm head shim thickness is Novarossi standard.

same problem here. manifold holes are easily ripped, especially with a hotter engine like JL. I will use mugen 2501 manifolt, or nova 5fin manifolt on mine.
