vespa SI CARB big MJ 180 test | quattrini M1X | FMP- Solid PASSion |

Описание: will a HUGE 180 mj even work? which main jet does it need?

as in some countries humangous mainnjets are used and recommended i wamt to show you that this is just am indicator of fuel supply issues, too little fuel delivered. with standard good fuel supply for tuned engine such HUGE main jets of course drown the engine.

ie m244 quattrini reed valve with box and 30hp needs a 130mj, so why would a simple rotary valve need a 160mj? it does NOT of course.

1) If huge mj are rideable, not enough fuel is provided.
2) if there is enough (too much) fuel, a huge mj is NOT driveable, it drowns the engine.

defect: 2 big main jet ;)
solution: take a smaller one :D
