Ugh. Did you ever figure out why it seized? Rust?Scrogs10 said:I had they same thing but my right side screw was seized. I spend an afternoon drilling and digging out the screw head. There was a time I thought this is looking very expensive but I kept going until I could see some clean thread. Then I could see the light at the end of the tunnel. I ended up removing the entire head of the set screw in tiny little pieces with a fine screwdriver chiseling them out.
I did break a small part out the casing but not enough to cause a problem. I could feel the spring moving once the threads were clear . I pulled the spring out and thankfully the seat was untouched and I had enough thread to fit new screw set with seal.
All this was done with the throttle bodies on the bench. I'm very pleased to say all is working well. Though I still cant get them to balance properly. But at least both screws are adjustable if needed.
What did you do to prevent it occurring again? (You mention something about a seal, I think you're referring to the rubber nipple cover, but I'm not sure).
Do you know why they wont balance, or anything about the cause of that problem?
Lastly, what year model cycle are we looking at?
