    Volvo 501b distributor mechanical advance

    Hey Gents, I have a 1993 volvo 501b which has a (I think) Pertronix distributor with the weights and springs to manage the mechanical advance. It has the star wheel / hall sensor electronic ignition. The springs and weights are pretty crufty for the mechanical advance. I'm thinking I can...

    Water in trim oil.. how to find the source?

    Patient is a volvo 501b 1993. The trim oil has water in it. The drive does trim up and down. I have no visible leaks, but after a bit of trim use, the tank will overflow as water infiltrates the system. Question: How do a trace where the water is sneaking in? I don't see any fluid leaking...

    Volvo 501b - what carb?

    Hey there - I still have not solved the issues with my Volvo 501b. It stumbles on hard acceleration, and it stumbles hard at WOT. Eventually, it boogers up the plugs and barely runs at all. I had the Carb rebuilt, but I'm starting to think the rebuild is not cutting it. I'm considering...

    Volvo 501b from hell... What am I missing?

    I got a shaggy dog story for you: 1993 Volvo 501b in a Larson 20sei. At the end of the '04 season, my wife hit something submerged, kicked the drive up and broke off the raw water elbow. It ran great.. until it melted. Heads were warped, water in the oil. Local shop wanted to install a new...
