Ah! That makes much sense. I've been trying to find it in the shop manual. I thought it could not be doing much during startup, since it's vacuum-driven. Thank you sir, you've been most helpful. I just got the tranny rebuilt, and want to take it on a nice long drive. - Theron

Not sure what it's called. but it's a vacuum motor on top of the engine that yanks up on the throttle linkage. I assume it's the high idle throttle for starting. It was disconnectified when I got the car. I hooked it back up and it seems to do nothing. Engine runs great when warm, but barely starts when cold. Is this an essential component to Z-related happiness? I know Zs need to be choked until they warm up a bit, but would a properly functioning unit improve my starting situation? There's a red adjustment screw on it that I assume would adjust it in some way. It's a '70 HLS30, stock as a rock.

After a few years of sitting, my '70 240 is back on the road! It's #4446, mostly completely stock. Engine purrs until it growls. Tranny is a bit noisy, but it shifts fine. Only things I changed are the clutch (280), the springs (Tokiko), and the fan assembly. Dash has minor cracking. Only minor surface rust (needs paint) except one spot by the back wheel. I have the new metal. I live on a beautiful mountain highway, so driving is a lot of fun. I may sell it, if I can get myself to let go of it. Cheers! - Theron
