Adjustment of CO content with screw 1 of mixture quality (composition) using key KDEP 6.35
The carbon monoxide (CO) content in the exhaust gases is regulated by screw 1 with a hexagonal socket for a key, closed with a plug. The CO content is reduced by tightening screw 1 with the KDEP 6.35 device.
Do not increase the crankshaft speed with the KDEP key inserted into the screw, as this may bend the air flow meter pressure plate lever.
Idle speed adjusting screw 2
The idle speed of the crankshaft is adjusted by idle speed screw 2. Turn screws 1 and 2 alternately until the CO content is less than 3% and the idle speed of the crankshaft is within 900±50 rpm.
