If replacement of this pin should become necessary, it may be accomplished as follows: First, remove the cap nut at the bottom of the rack and pinion housing. Next, turn pinion shaft slowly from right to left (facing toward the carburetor) until the bottom of the metering pin appears at the bottom of the pinion shaft housing. Continue to turn the shaft slowly in the same direction, releasing the connection to the dash control if necessary, until the rack to which the pin is fastened drops out. The palm of the hand should be held to receive this as the parts are very loosely assembled. The pinion shaft should be retained at the exact position at which the rack is released. Install a new metering pin, the way to do this will be obvious, and return the rack to its proper mesh with the pinion. Replace dash attachment (if detached), replace cap, adjust per instructions given on previous page.
The loose assembling of the metering pin in the rack is for the purpose of providing for freedom of movement of the metering pin and in order that binding in the aspirating tube may be avoided.
The gasoline filter is installed on the carburetor at a point where the fuel pipe is connected.
The pressure within the gasoline tank forces the fuel through the pipe, through the filter screen (ZO in the filter) and thence out through the opening to the carburetor.
The filter cap CC may be removed by turning the flanged nut on the bottom of carburetor to the left, thus releasing the inlet fitting.
The filter screen or strainer should occasionally be cleaned. This may be readily accomplished by removing the filter cap to which the screen is attached.
The filter should be screwed up tight when replaced.
