here is a question, and a possible answer to the coil in the exhaust side of the pressure tubing on cars. First the question...
I run coolpower (total synthetic), never had a problem with any engine I have ever owned, and all have great compression. I know that castor is added insurence, not to mention rust prevention. My question is this: What is the big deal about all syn. fuel? Some people will not run this fuel cause of concer about there engines. Please shed some light on this as I have never had any problems in my engines, they are very clean inside, great compression, and run great. This includes four strokes.
Now the other issue...the reason I here for the coil in the exhuast side is to help dampen pressure pulses to the carb. Cars are driven with lots of throttle action. I don't know if this is the case or not, but it's is what I have heard.
