Been a busy summer here. Finally got a free morning to address poor performance on the K20 350. Had already done a full tune up, but still backfire and miss.
Pulled the Ebrock 1406 and opened it up. Secondary circuits pretty plugged up. Soaked everything in carb cleaner, blew out all passages, rust in the bottom of both bowls. After finding the choke rod I dropped, reassembled.
Runs like it should now. Happy camper.
