its not porus like a primer, its not UV rated, it will go milky in the sun, but is otherwise fairly resistant.

i have used it by itself, under cars, or as a base/sealer to be top coated

 

currently my ute tray is sitting in it from bare metal 4 years ago without any signs of degredation (so its not porus as primer would be showing rust)

i have had it peel a table frame, it was heavily pitted, i flapdisked it and hit thr pits with wire brush on grinder (no chemical rust removal), brushed durepox on and then left it outside in the rain. the rust spread under it after about 3 years where it was touching the ground

 

 

it sets really hard, so if you get a run or whatever in it and you are going to topcoat then best to sand the lot within a few days rather than weeks.

brushes well, fairly self leveling

 

They will also tint it a bunch of colours

Thanks guys. I’ll get it to use as an all in one. 

I’m thinking I might brush/roller it on just so I don’t have to deal with overspray etc. Remembering this is a patina car, not a show pony.

What carb does it run? Just had a couple rebuilt by the dude in normanby, he does such a great job and is familiar with most anything. He did my super snipe ones years ago and that thing ran like a clock.

Yea I'm interested to know what carb too. I'd say that vacuum advance was cooched for a while so someone had just tuned it to run without it, hence the timing being way off.

Posted

Yeah that was my theory as well, the timing was way off and the carb was full of sealant, so I think they had been chasing that issue for a while.

It is a Holley 600(650? Can never remember) 4150(4160?) vacuum secondary

Sounds like it might have a blocked idle jet.

Did you fit the carb new out of the box?

Does it react when you just the idle screws? Or can you turn them right in till they stop and it still runs?

Posted

It is the carb that was on the car but I have ultrasonic cleaned and re-kitted it. It responds to the idle screws.

There was a lot of blue silicone to deal with though, so it might be worth me pulling it apart again to check over

You can get different plastic cams for the accelerator pump lever that will make it squirt earlier/later/more/less but this is really super fine tuning. 

Also check the adjustment screw on the accelerator pump lever

Accelerator pump is set correctly. Yes vac advance on the dizzy.

The accelerator pump feels like it is working well, it comes off idle really nicely now, it’s just the high vac situations that are terrible. Idle and low throttle cruise.

Are you sure the vac secondaries are opening? I think you can put a rubber band or something on the linkage to see if it's opened properly. Maybe the diaphragm is leaking?

I have the same carb. Pretty sure the standard ones have fixed secondary orifices. I bought a kit that added a plate with replaceable jets. I also bought variable rate secondary springs to tune where they come in. You shouldn't feel a sudden surge when they open, it should be fairly smooth.

They're a good carb and reasonably simple. Loads of online help available in American forums etc...

Have you checked the vacuum advance on the Dizzy?

Pull the hose off the carb and suck on it, see if the advance plate moves in the dizzy. Also this hose should be connected to the base of the carb for best function.

Another thing to check is the power valve on the back of the metering block of the carb.  One back fire through the carb can blow these.

I’ve just gone over the air idle again since I did the last float adjustment and now it’s running really nicely 🙌

I had some dried fuel in the secondary needle and seat in my 600 Holley a while back from not getting used much. Made it leak fuel and idle like poos. @Shaz's Dad told me to clean it out and use my car more......... Bit of W.O.T to open up secondarys flushing fresh fuel through can't hurt now and then aye. Totally sick car too mate you've done really well getting it sorted, well done.

Thank you!

I get a bit disappointed now and again comparing how rough it is against my mustang, I’m starting to feel the need to paint it…
