Title: Works Great & it is a "Dial Back Timing Light"
Review: It does not state it anywhere in the desciption on Amazon, but I figured it had to have this feature because it was a feature rich time light. On the C3 Corvette fouum all they talk about is a dial back timing light and how helpful they are setting up the vaccume and mechanical advance on older cars. After purchasing this light to replace the 50 year old timing light used by my day I must say I agree. The 5568 had no problem picking up the spark from the 8 mm plug wires I am using like some others stated, the manual says ti works up to 10 mm.
Is the review positive or negative?
