I know that there are many threads but want to bring another in to play for thoughts. Over the weekend I replaced my rockers and arms ( don’t know the name) everything went smooth and I have had cable upgrades from jeepcables.com sitting around for months that I decided to put them in as well. Turned on and was great, idle super smooth so I didn’t die. I let it run for about 20 min checking everything and at turn off I have this weird rattle and little squeal which I never have had. Alamo at feels like it got a bunch of extra power at shut off or a last burp of gas. I’m trying to figure out what I possibly did that would now cause this… another worry and more cost!!!! It’s. A bit vague I know but would upgraded cables do this? Thanks everybody.
