rebuilt my hitachi 2brl carb, DCJ 306, on my 74' DL. still running a little sluggish, gonna replace the spark plugs and see if that does anything with the way it sluggishly gives power at the beginning of any throttle demand. or should i just take it to a carb. guy and have them tune it right? lol anybody know where i can get a driver side inside door handle for my subi?
