"Fix" a slow Bonzini rod
« on: October 03, 2021, 10:44:06 PM »
Any tips for fixing a slower Bonzini B90 two rod? Visually it doesn't look bent, and it's totally playable.

But I can hear more metal on metal between inner/outer when gliding and it's not as effortless compared to the opposing two rods.

I should note I use Super Lube Precision Oiler (Oil with PFTE).
