I was having weird high idle problems. After a longer time period than I'd like to admit, I realized that it happened only after applying hard throttle, and noticed that the return spring on the (~10 year old HP EFI) TBI secondary throttle plates was knocked off at some point, probably when I pulled the engine last. 🤦*♂️

In its neutral position, the spring leg that goes on the throttle arm points down. So, 1/4 turn re-seats the spring. Thinking that was probably a bit loose, I twisted the coil a full revolution (well, I guess 1.25) and then hooked it on. Seems to work and feel OK, but I can't find anything that tells if I should try to crank it around again, or if it was right at the lower tension 1/4 turn, or what. Help?
