I’m back!
Here’s how I fix these sloppy and leaky shifters after obtaining a length of brass tubing from the hobby shop.
After cutting it to length and deburring the ends, the exhaust housing gets drilled out to accept the short piece of tubing. Epoxy or crazy glue can be used to seal the outside of it. Sometimes they slide right in, sometimes they need a bit of persuasion. Once the shift lever is fitted with a new O ring and some grease applied, both the slop and the drip should be gone.
