This is a sun tune up card for 59 235. You will note that the dwell is expressed as a range from like 28 degrees to 35 degrees. So you set your points and then check the dwell to see if it is in range. So that’s what you are looking to do. Not really a more precise specific number, but a range that you want to fall into after setting the point gap.
Thanks everyone for the information and discussion. Following Jerry's regular advice to "test not guess" I'm bringing as much information, as well as assorted test equipment, as I can to help figure out why a freshly rebuilt engine has developed running problems. I don't actually expect the dwell angle is the problem but I'll want to get all the basic stuff set properly before drawing a conclusion. If we can't find out what's happening with his engine I'll be starting a new thread---with more information--and asking for your help again! Jim
Don't forget changing the dwell setting will affect timing as well. You will need to retime. As a general rule on a 12 volt engine 30 degrees dwell should get you in the ball park. You will need to find a spec sheet for your engine for the correct dwell
