So aparently you have to change air filters in these things every 4 years or so...... but on the bright side, it sounds so good right now. I took the filter out, turned the idle mix screw to 3 or 4, and bumped base timing to about 11* advanced. The fj60 dizzy is mechanical advance only, so I’m not too worried about needing to recurve it. I get to analyze a weeks worth of telemetry this weekend after installing the updated speedo. Looking like I’m getting 160ish city miles from about 12.5 gallons of regular 87 octane, maybe only 150..., so better than 12 mpg. Maybe after the air filter change it goes up!
