| 30 HP CAR G.U.L. 19. SIDE VIEW AIR SILENCER CONNECTION PIPE CLIP-ON PIPE FROM SILENCER TO CARB: CARB CHOKE SPINDLE END VIEW SLIDING JOINT CONNECTION PIPE TO CARB: RING NUT WITH SPHER: SEATING. AIR SILENCER TROUBLE HAS BEEN EXPERIENCED ON THIS CLIP A.{Mr Adams} IF THE CLIP IS TIGHTENED TOO MUCH THE PRESSURE DISTORTS THE TOP OF THE CARB: AND ALLOWS THE BUTTERFLY CHOKE TO BE TRAPPED. ALSO THE RING NUT ON THE CONNECTION PIPE IS NOT NECESSARY. THE CONNECTION PIPE CAN BE TAKEN OFF WHILE THIS NUT REMAINS TIGHT. THE SLIDING JOINT ON THE CONNECTION HAS 1/16" CLEARANCE, THIS IS VERY BAD, AS IT CAN BE RATTLED ABOUT IN THE FLANGE. K SCHOLES. | ||
