Been going over the 68 144S engine wise. It seems to be running better but maybe not where it could be. It was stumbling a bit but adding to the dashpots seems to have cured that. I had cleaned the filter at the fuel pump and changed the in-line filter from the pump to the SU carbs. I set the timing by hand and that seemed to wake it up pretty good. Got a timing light and saw I was more towards 30 degrees before top dead center. It was a bit harder to start. I brought it back to 20 degrees. Power seemed to have dropped off since. I noticed the screw through the distrubutor was loose that holds the points. I had a new set of points so I put them in and got the screw tight. The cap looks good. The plugs look good as do the wires. I tested the wires with a Fluke meter. Number one was a bit higher then the rest. The coil wire was higher then number one. I set the point gap and checked the timing again. I have adjusted the jets a number of times as well.
It just seems to lack power but not sure. When it sits overnight it takes a good bit of cranking to get it started and is pretty touchy with the choke to keep running until after the first few minutes. Normal? When it is cranking it doesn't even seem to want to fire. Seems fuel related. Colder these days in PA but has not been real bad as yet. I keep it in a unheated garage. Once warmed up a bit it fires back up right away.
Any thoughts over-all or other things I might want to check?
