That was never a problem, they didn't start the best cold anyway. That's why the late models had advance so they started better. JD 3010 and 4010 models also came originally with fixed phase, no advance pumps. When the 3020 and 4020 came out with advance for better cold starting RoosaMaster/Stanadyne came out with an advance housing kit to update the 10 series as well. Most owners bought it around here, but I still see some early no advance pumps in for repair too. Problem with the fixed phase pumps is if timing is set for best starting, engine will miss at high speed no load. Set the timing for best high speed running, then it will start hard. Rotary pumps with advance helped eliminate that problem, especially with constant end, variable beginning designed pumps like Stanadyne/Roosa, and CAV DPA pumps are.

After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
