Once you are ready to remount the new HDA-203 carb, turn the white fuel line L-fitting to about a 30 degree angle from its original position. This will route the fuel line under the carb.  Temporarily mount the carb through the airdam assembly, route the fuel line OVER the throttle linkage, then check and mark where the fuel line would need to go reach the fuel inlet of the carb.  Once you know where the fuel line would need routed through the air dam, remove the carb and air dam, then drill through the air dam using an appropriately size drill bit. File down the hole edges.  Remount the carb and air dam, then connect the fuel line. Check where the fuel line rests now on the base lip of the air dam. Place the air filter onto the air dam and push it into place. This will pinch the fuel line between the filter and the base lip of the air dam, and show where a clearance needs to be made on the base lip of the air dam. Mark where the pinch occurs on the base lip of the air dam, then cut a generous amount of base lip for the fuel line clearance. Once your happy with the fuel line, continue to adjusting the choke linkage.

For the choke adjustment, I am not going to describe how to do this, as its trial and error.  With the air dam and carb mounted, you need to make small adjustments to the choke linkage, flip over the choke tab on the carb, and continue adjusting until the choke can be locked rearward. My choke lever adjustment is still not 100%, but I am able to get the saw started as if were new.

Once the choke lever is working and your happy with it, the repair and mod is pretty much complete. See pictures for detail.

If you haven't already, remove the limiter caps from the carb. Sand down the taps, then replace them to the carb.  Screw the adjustment screws all the way in, CAREFULLY bottoming them, then set the L & H screws to 1.5 turns out.

Finish reassembling your air filter, install the bar and chain, fill with fuel mix, and attempt to start the saw. The saw should start as it normally would once the fuel gets cycled through the carb, but the chain may start spinning and the idle may be weird. Blip the thottle and wait. It should run idle without stalling. Once warmed up, tune the carb!
