It seems to be inverse of the 212 I'm used to. At the "idle" position ( throttle arm forward), the carb is actually wide open.. 1. With the engine running, loosen the throttle cable clamp screw enough to slide the cable. These are basically flat bed trailers with vertical stakes to hold logs in place Common lengths: 40'—53' (singles) 28'—32' (tandems) Common axle/wheel ratios: 2 axle/8-wheel, heavy loads use 3 axle/12 wheel or 4 axle/ 16 wheel configurations Some loggers are equipped with cranes for loading and unloading timber. Vertical clearance for double-deck buses. For double-deck buses the recommended minimum vertical clearance is 4.6m to static obstacles (such as verandahs) and 4.8m to changeable obstacles (such as trees). The extra safety margin for trees is to allow for changes from new growth and wind, snow and rain effects that occur in between inspections.
