Could you please explain this to me. Thanks. ignition timing is telling the spark plug when to fire in relation to piston position. first off, do you understand the basic principles of how an ICE (internal combustion engine) functions? lets figure out where youre at first so we know where to start. the good news joshua, is that by the time we're done with you, youll be able to build your own jeep. :-) -- Nathan W.

So, I admit, I don't know what > "Timming" is. Could you please explain this to me. Thanks. They are talking about the way I have my CJ7 engine set up. I have a hot 'timing' curve on it, or hotter than stock anyway. It is how much and how fast the timing advance is set up to. I have my 258 tuned manually with no computer or knock sensor working on it and a high voltage coil, an Accel SuperCoil. If I use regular gas, my engine pings like crazy or I have to adjust the timing to run it and it still pings. On a computer controlled engine, the knock sensor adjusts for gas automatically by retarding the timing if needed. If I retard my timing to run on regular gas, my power and mileage go to ---- fast. It makes about 100 miles per tank difference and about 1500 rpm or so off the top end of each gear. On my computer controlled Cherokee, there is no difference in mileage or power running high test or regular.

Re: Premium Petroleum
This is all well and good, but Josh (the OP) has a new SE which is the 4
banger, so he will get no benefit from high test gas. He would get much more benefit from getting a good winch.
