Spark-Lever Posistion

The phillips spark advance (nurex) works on the same principal,and is effective.I prefer the function in the distributor,it makes any maintenance required easier.

I put this on the wrong post.

How so. The Nu-Rex operates on a Gyro. There is no "maintenance" unless it breaks, which i doubt will happen. It is bathed in oil being splashed around the valve chamber so no need to lube.

50% of the advance will make my engine over heat!

How so? You dont have to tear the valve cover off and remove the distributor if you have a problem..both systems work on centrifugal force,both work well,good luck with your phillips.

And here I thought part of the fun of owning these old monsters was getting used to how to operate them.

The mechanical advances do not respond to load unless they also have a vacuum diaphragm to retard timing when the vacuum drops relative to load.

You are correct. That is why I set my initial timing retarded so I can manually retard the timing when going up a steep grade. With the Nu-Rex/Phillips you retain your timing lever.

It is such a simple thing to adjust the spark as needed. A little know-how and some common sense is all that's needed. I'd say if someone can't figure it out, they should stick with a Toyota.
