So advancing the timing through vacuum advance is for cruising speeds, not romp on it speed? That's why everybody sets theirs to max advance to begin with?

Great news. I tried to remove the original sticker and glue it back on the reconditioned one but it wouldn't come off as a whole piece. So now it's just black. My rebuilt one didn't need any push rod adjustment at all, it was still at the right length. Have fun installing it, for me it was almost a PITA.

It was done that way by the PO. I'm guessing the vacuum advance will work properly now? That float jet should be here Friday, and if it's not raining Saturday I'm going to take it for that "spirited drive" Blue talks about when adjusting the nozzle height in his Quick and Dirty tune. I've been chasing that drive since I bought it.

I followed Dr 240Z's advice and they turned out great. Thanks again for the write up.

He's good at that! Make a Wish should've included a mechanic with his car.

So my 240's vacuum advance has been plumbed off the balance tube, manifold vacuum, right? It holds at 17 on the vacuum gauge at idle then goes down to nothing with RPM increase. The front carb vacuum has been plugged off until I rebuilt my carbs. It barely has anything until the RPMs raise then shoots to almost 20 on the gauge. The butterfly opens exposing the hole. That's the way I want it, right? Port vacuum for the vacuum advance on the distributor?

They build character.

And here I was 2 hours away with SU parts strewn all over the place.

Not so much anymore. Life got in the way.

The wife?

I bought 2, one works. There is a small spring inside the plunger/needle then a cap with the pin that contacts the float. The clip on the top that holds it all together doesn't move enough to let the cap and pin move up letting air or fuel to go through. I attached the old float chamber to nozzle hose on the threaded end of the valve and couldn't get any air through. I've got a strong set of lungs, my friends get mad sometimes. I don't want to shorten the spring or bend the clip. Z Therapy is sending me a replacement and I'm sending the faulty one back with the nozzle cores

The DVD is a must for folks like me, I learn from example not written text. The best thing to me was a side comment by Steve when showing the nozzle's tip being flush in the venturi, "if you leave the chokes up it'll puddle up and drip down the nozzle" or something like that. I have a 3 car garage and 5 cars. I'm constantly moving cars around and always leave the choke pulled up. My friends are scared to come in the fumes are so bad. Now I know why. It's a common sense format. I want to work on them now where before I was too anxious.

Talk with Bruce earlier, he was surprised that a simple valve wasn't working but said they would send me a replacement. I can only guess the needle is a bit too long for the valve body and the retaining clip is holding it down. If I pull the pin out about an 1/8th of an inch it opens up and lets air pass through. This 240 is teaching me something nobody else has ever been able to do, parents, girlfriends, psychiatrist, bosses and friends, PATIENCE. Medication works well, I must admit.

Right, no fuel entering the float chamber.

I would think if I blow into the threaded end air should come out until I push the pin in, right?

It's like taking before pictures, I don't think about it until it's too late.

My cheapo EMPI buries the needle on the 3,000 RPM test.

I had to put my 17mm crows foot on an impact wrench, compressor at 130 psi, then use a propane torch on each and every one. I don't think the valves had been adjusted since new, 1977.

I've been reading the past hour on those filters. I'm leaving mine off. Thank you Blue for the fix. If the valve gets clogged and starts leaking out the vent barb I'll put them back on.

Does everybody use these or throw them away? My rebuild kit didn't have new ones but I cleaned the old ones up and they still look squashed together. I'm thinking of putting filters before the fuel inlet on each carb and not using the old "last chance" filters. Am I making a mistake? Thanks for any replies, Cliff.

Good to hear it was an easy fix. That's the only good thing about being scatterbrained, I can't stay focused on one thing too long.

It's so easy to apply and then wipe off I could clean them up every now and again. I now see that the carbs will need a periodic once over anyway. I thought everything was clean until the Never Dull came back darker and darker.

December 1st, 15% off everything except wheels which will have free shipping only. I may get a new set of tail lights myself, they're not getting cheaper as time goes by.

I'd never heard of that stuff, now I'll never forget about it. It's exactly what I needed for the "final touch". Thank you, thank you!

Yes I am. After watching the DVD I thought I had the wrong float valves, they weren't Grose Valves like in the DVD. So after a quick Google search I learned they were no longer available. At first I was going to rebuild a spare set I bought but when I realized how badly they'd been messed with I decided to go ahead and rebuild the original ones that were on the car. After taking them apart I can see I was driving half of a 240Z. About to watch the DVD one more time and go put them together this morning.
