This 4140 with 172 gas has started instantly in the 6 months I?ve owned it. Same this morning, except I backed it out of the shed and it quit.
1. The fuel bowl is full and clean
2. Pulling the drain under the carb shows good fuel flow
3. Points are clean and set properly
4. With dist cap off, can see the points sparking
5. Removed wires from coil and cleaned terminals
6. Pulled lead wire from distributor to watch for spark. (It is the kind of wire with no copper, some sort of black fiber)
7. Spark seems weak. I can barely see it in daylight
8. Pulled a wire from a spark plug to watch the spark. Didn?t see the spark but got a whale of a shock
9. I know better, but shot a bit of starter fluid into the air intake
Nothing has changed since it was used a few days ago. It has spark and fuel. Any ideas are much appreciated. ?Peter
