My alternator belt is really noisy...it's hard to describe. Not a squeal like a loose AC belt it's more like a squeakey knocky sound. It's been getting worse for a few months...it used to go away once the engine warmed up but now it bad all the time. The belt has about 15k miles and the tension feels about right - a little play between both pulleys. I have not tried to adjust it yet. Can't remember the brand of the belt but it has a ribbed surface (i.e. not smooth belt against the pulleys). Out of desperation and because I had a can in the garage, I sprayed it with CRC Belt Conditioner and holy crap the noise got much louder (same weird noise just louder). Any recommendations for quieting it down short of replacing the belt?
TIA, Mike |

Thanks. I'll try a new belt and check the brackets bearings etc while I have it opened up. I'm currently dealing with a plugged Weber idle circuit on #3 that feel like theres a chunk of rubber in the idle jet hole. It's definitely not the o ring but when I try to install the jet something squishy in the hole keeps pushing it out. I can remove the jet and the mixture screw while running and it makes no difference. #3 CHT doesn't move when I start the engine. I tried carb cleaner but no luck. Looks like it's carb rebuild time.
