Intake Trumpet DA-50R and DA-35 with 2 screws M5x60
This is the same as the intake trumpet #0081, but including a pair of M5x60 socket screws. Apply only a minimum of Loctite to the screws, Loctite must on no account enter the crankcase.
Only tighten very lightly. What appears to be a simple rubber gasket holds down the reed valves and must not be squashed unduly.
