Can you borrow a timing light, either the in-line or clamp-on (Snap-On) type which will show whether you have a spark on each plug when you crank the engine. I didn't know that clamp-on testers existed. Difficulty in testing the HT side has sparked a lot of discussions recently, and there may be others who are currently suffering. What's the cheapest that that you would consider buying... and are there kind Members who would lend one? Thanks Jonathan
