After some ups and downs over the past week, and the engine knocking, I decided to check the points again.
After checking and trying to regap, I found that the points set screw was stripped. So, I’m thinking now that the problem with the engine knock was the points not being seated properly(or bouncing around) instead of the marine gas.
Stripped points screw? So what’s the fix? Found one other rebuilt 021 905 205 P but at $175, need to hold off for now. I decided to move up one screw size and went with a stainless steel 8/32″ screw. The smallest length I could find was 1/2″.
Since all of my tools are packed up for an upcoming move, I used two nuts and a hacksaw to try and get the screw to about the same length as the OEM …about 3/16″. After trimming and filing, tried in the distributor and it fit. Reset the gap as close to .016 that I could… was a little difficult since when tightening, the gap would get smaller, so used a larger gap, then tightened.
After resetting, went ahead and checked the dwell which was at 51°. The range should be from 45° to 52°, so after the big flub up several days ago, I decided to leave at 51°.
Grabbed the timing light but couldn’t remember the settings exactly so got the timing close and cranked it and she purred just like before, but this time, without the engine knock. Great birthday gift for the day. 🙂
