I have a Chrysler 70 hp, Model 707HE, Serial: 6147 (not sure of the year) but it has points. I have tuned it up but do'nt have the manual yet and am looking for the Gap (manual is on the way).
The motor has Magna Power CDI ignition.<br /> Point setting is .013-.015. <br />You may want to wait for manual before doing any trouble shooting of the ignition.
The information I have(Chilton's) says that your engine is a 1972 model. The point gap in the book is .013-.015 . It also says the spark plug is the Champion L-20v. As far as compression, all it says is that the cylinders should be within 15 lbs. of each other.
