markjs_pnw Posted September 2, 2019 Share Posted September 2, 2019 I set it about 800RPM but no matter what most of the time it ends up stuck at 1200? What's sticking and how can I fix it? This car needs hardly any warm up, engine runs beautifully except for that. Quote Link to comment Share on other sites More sharing options...
DaveT Posted September 2, 2019 Share Posted September 2, 2019 Check the choke thermo spring, shaft, high idle cam. Maybe sticky or broken? Quote Link to comment Share on other sites More sharing options...
markjs_pnw Posted September 3, 2019 Author Share Posted September 3, 2019 Passenger side of carb or drivers? I'm intimidated by my otherwise nicely running Hitachi, lol Quote Link to comment Share on other sites More sharing options...
DaveT Posted September 3, 2019 Share Posted September 3, 2019 Iirc, all of that stuff is on the side where the throttle cable connects to it. Passenger side. Quote Link to comment Share on other sites More sharing options...
KiwiGL Posted September 5, 2019 Share Posted September 5, 2019 Download how to keep your Subaru alive (can be downloaded as a pdf from suberdaves site) and read the section on idle tuning. It's a great reference, very easy to follow. That's how I tuned mine. In my case, I had a similar problem, it would idle at 1200 rpm and got to 2500 on cold starts. Turns out the throttle cable was too tight. By slacking it off a little I was then able to adjust the idle speed screw to get it perfect.
