Way up in the middle there’s a large flathead adjustment screw. It is the typical location for idle speed adjustment on carb’d models as well. I will bring it up to 1000 +-50 today. It’s gotta have some gas since it’s nearly empty and I’ll adjust it while it’s warm. Thanks for the help everyone! I learned way more about this system now. I’ll be riding it down to meet someone today and I’ll probably post one more time the results of that ride.Have to ask. How did you adjust the idle. Did you use the idle screw that is on the throttle linkage midway between the right left cylinder bank, or the screw under the CFI cover on the right cylinder bank?
Looked at the YouTube and the engine does sound good. Noticed you have the dash on the oil temp/pressure settings as well. I'd bring the idle closer to 1000.
