1977 620 L20B Tucson, AZ
Just bought her last weekend...
When I went to check it out, it started but didn't stay running. I bought it anyways, lol. Engine had been rebuilt 6000mi earlier, supposedly.
Changed out the starter (Old one wouldn't always engage) in the guy's driveway while my mechanic friend adjusted the float tab to get fuel into enough fuel into the bowl and added a pressure regulator for the aftermarket electric fuel pump. Been running well since then. Changed the plugs, oil, trans and diff fluid, coolant and drive belt. Oh and replaced the fuses. Just keeps improving.
This weekend got the timing done, found out the distributor/oil pump was installed incorrectly. Was still able to advance the timing 12 degrees to spec. She's purring nicely now.
