1935 Ruby has suddenly developed an engine fault after running smoothly with no engine problems. (Compression check on all heads 94 to 98psi)
The symptoms are as follows.
Engine starts easily and runs smoothly for 5miles or so. I then stop at traffic lights and on starting to run again the engine develops a misfire and runs rough. I change down and rev hard to build up speed the misfire continues to get worse then better but generally sounding like a misfire.
So far;
I’ve change the plugs, same issue but then disappears for a few miles before the problem returns.
I’ve changed the Bosch dizzy condenser (no change).
I’ve checked the point’s gap (0.015) and checked the rotor arm (no change).
I’ve swapped and changed the fuel pump and in line filters (no change).
I’ve cleaned out the 26va carb, removed the jets and blown them through (no change).
So at the moment I’m stuck as to how to proceed.
Any suggestions, ideas or thoughts on how to move on will be greatly appreciated and tried out.
