Pinesol works wonders on carbs.
Thank you for the input...
I did some research on the net on what products can clean an alloy throttle body and I got 2 dozen different opinions and experiences on what product has been used and what happened.
I was thinking about soaking it in a solution like overnight to help reduce the work to clean it out, but I'm not sure WHAT solution would attack the aluminum in the TB. From the look of it, I'd guess that it is 30 years old and never been cleaned.
