Hey guys just after some advice of jetting sizes. Recently my brother scored some 40mm Mikuni off a Toyota 2T-Gs engine. On initial inspection the look in good cond with centre pull linkages still attached, plan is to use these with his existing throttle cable.
The Datto has a freshly rebuilt fairly standard L20b engine, 1mm over bore, SSS cam, points dizzy with working vac advance, comp ratio is about 10:1.
The phh40 carbs have the following: They are type S4, they are not the anti pollution type YAY! Current jetting is 52.5 pilots, 200 main air, 135 main jet, #8 jet block. These look to be stock 18R-Gs jetting combo except the Toyota pilot jet is 63.8
Sound like a good starting point? BTW the car is driven out of melb 800m above sea level.
Cheers
