Your engine doesn't have to be fuel injected to have a knock sensor. It is a safety device, really, because they are doing all they can to max out the engine's power and not reach the detonation point on low octane fuel. Even if your compression is relatively low, I bet there is. I had to set the timing on my Beetles to the point just a bit more retarded than hearing a ping under hard acceleration. In other words, I retarded under WOT until I heard no more knock or ping, and then a couple more degrees, to prevent damaging the engine. I usually set the compression on my engines at around 8.3:1 or so. Most I did was 8.5 A knock sensor will retard the timing automatically, so there's no guessing. Now, with a hydrogen generator added, retarding isn't neccessary, and I could set my compression at more than 9:1. I just may do that next time I build one... If there is a next time? Stanley

It retards the timing to prevent detonation making less power causing you to open the throttle more. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
