Engine rebuild is finished. Engine back in car. Just realized I lost the short rod along the way. ( It's always something!)
I happen to have an extra long rod I found in my old parts box.
Can someone tell me the total length and and the threaded length on the short rod.... I'll cut down and rethread the long rod I have.

Thanks!

Larry

Larry, I just pulled the SPICA intake from my car to use in a new engine. The short rod is 89mm long, threaded portions 22mm on each side. Threads are M5x0.8.

It's not a set distance but I'm sure there's a ballpark distance. Once you're set the bellcrank stops for no and full travel, the short rod is set just long enough so the the throttles close and the bellcrank hits the "no" stop at the same time. You want to hear both at once. If you feel the throttles closing and no "clack" of the bellcrank stop, adjust a half turn. Similarly, if the bellcrank hits the stop but the throttles are not closed at the same time, adjust a half turn. Or more if needed. It takes some feel, like getting the jet centered in SU carbs.
