Who uses the Nu-Rex wrench to timing car?

[Dino's A]

Can I get some feedback on how good the Nu-Rex Nu-wrench works in timing the engine? I was watching the video on how it works, and for someone semi-new to this motor, it looks fool proof. Is it?

[pgerhardt]

It works fine, but remember that the initial timing is just a starting point, and that the actual timing while driving is determined by where you put the advance/retard lever. There is no reason to obsess with getting the timing perfect within a fraction of a degree.

I'm new to Model A's as well. I've used the tool several times lately and it works as advertised. Just follow the instructions, works like a champ

The object might be to set the timing up so that the advance can't go past 30-32 deg. of crankshaft.

I have one, have used it, but prefer doing it the old fashioned way.
It's OK for getting to a starting point, or on the side of the road emergency.
If the simple question is "does it work?" The answer is yes.
Is it perfect for every car, no.
Each car is a little different, that's what makes them so special.

I like mine!
It is great for pulling the slack out of the dist shaft. I also time the cars with the light bulb.
Some good youtube videos on this subject. Jeff

I like it. I go up a rotor tab width advanced of where it lands. I think about 10 degrees. It helps to have something to hold the cam lobe while tightening.

Spot on, pgerhardt! Fussing over initial timing the way some folks do seems like a sign of OCD. If they are really that concerned about the timing, they need to adjust their timing lever to fit every driving situation. That is, advance the lever as the engine speed rises, then retard the lever when they upshift and the RPM drops. Then advance it again as speed climbs. Advance a little more when cruising on level ground. Then retard it a bit then pulling a hill to avoid detonation. Yet, who does this?? Even the OCD owners tend to just set and forget their spark lever!

Not very effective; we use a test light from points to ground and set per the Service Bulletins and other pub's to remove lash, etc. Get the cheaper wrench and bend like the Nurex.

I use the old wrecks wrench.

FWIW: I run my long block engines on a dyno before having my customers take delivery. I use the NU-Rex wrench to set up everyone that has a stock distributor. Works very good.
Good Day!

Boy, have I copped some flack for saying that on this forum in the past but what you say is absolutely correct. What is the point of setting the timing to within one poopteenth of a degree when the driver changes it as he drives - some better than others?

Agreed. Setting timing is just setting an initial starting point. Whether you choose to use the Nu-Rex wrench or use a light or a volt meter or just plain guess, you still have to get the dang thing on TDC and set the point gap.

Even the plainer wrench works well, for making slight adjustments & holding the cam, while you tighten the screw. Be sure to "hollow" grind a perfect fitting slot screwdriver, for this chore.
I hope this helps, I "try" to give practical advice, which has worked for me, PERSONALLY.
I collect Old Screwdrivers & hollow grind them, or make them into special purpose screwdrivers & awls, etc. "Sometimes" I can even "sharpen" Phillips Screwdrivers. They weren't zippiest design, I like SQUARE drive screws, when I can find the right sizes. They'd be GREAT, for floor boards. Chief, bless his heart, NEVER screwed his down, NOBODY could see them under his GREEN/BLACK, Liloleum mat, with MATCHING door panels---LOL

I just use the timing pin in the hole. Slightly deepen the depression in the timing gear where the pin slips in.

[midgetracer]

I use the Nu-Rex wrench and find it really speeds up the timing process and makes it more consistent. The wrench is cheap and easy to carry in your tune up bag. I also like the gismo that helps find TDC by using a spring to find the indent on the timing gear. I made a few of them from the original design.

Thanks to you all for the responses..I appreciate it!

This is my feelings on the tool also. You need to "fine turn" the engine after you get it close with this tool.

I'm not familiar with the term "fine turn". Do you mean "Fine tune"? Or is that something else?

I use the Nu-Rex wrench to set the "initial timing" then check it with my adjustable timing light so I can check total advance.

You are correct. Tune would work out better.
