Awesome Free!, nice quick response on the carby.
Getting closer to rego, bet your excited.
Well done.

Got the throttle bracket on & sorted out the airfilter everything else is hooked up. Not sure how to hook up the throttle cable but ill have a look at some car mags & see how others have done it

This should do the trick

Ive pretty much figured how the bracket will go on (can only go on 1 way) which means i gotta run the cable around the back of the motor. Need to take the carb off again & get 2 longer bolts as i figured the bolts aren't long enough to bolt both bracket & carb down. 

Also bought this, will drill a hole in the air filter base & screw this in & connect the hose that goes to the cannister

This arrived in the post today, not sure if it goes on upside down or downside up + now i think the bolts that came with the adaptor plate are too short now to bolt the carb down aswell as the throttle bracket.

Will still soumd like a bag of shit!!!, it has a standard exhaust fitted atm cos i was planning to go for a rwc & get it registered in my name. Sure sounds better with the twin 2.5". Im confident it will perform much better than the TQ was🤞
 

Ok so the clear hose pictured that's the one that was on the float bowl so that can be blocked off & the black one that went to the front of the TQ thats the one that needs to be fitted to the air filter base im assuming?

This is what it says about the ports on the carb, i now know rear is for pcv but have left it blocked off cos im using the port on the adaptor plate & i now know the one on the side is for vac advance (cheers Greg), just not sure what should do about the 2 cannister hoses

Yep that's what I'm on about. Sounds like you get what I'm saying... Can't wait to hear this thing run!

Ok gotcha now. You will either have to install a fitting into the air cleaner close to the carby entry or just hide/remove that purge hose altogether. If you leave it disconnected rather than hooked up to the air cleaner, there will likely be a waft of fuel smell constantly coming out of the charcoal can, especially on hot days when there is more vapour being produced out of the tank.

Don't block it though, your fuel tank needs to breathe through the can. Back when I was a kid, my XB ballooned its tank out from 80 to 92 litres when it somehow failed to vent. My dad (who owned it then) only discovered this when he went to fill it up and noticed that it took way too much fuel compared to normal.

The other hose (I presume) went from the float bowl on the ThermoQuad back down to the can. That should be plugged off there, just a short bit of hose with a screw in it will do.

Your Holley isn't sealed so technically isn't an emissions carby like your TQ was. It just vents the bowls through the small passages on top at the entry to the throats, to be burnt up by the engine. When stationary (not running), the fuel vapour will waft out of these vents and out through the air cleaner. This is why old cars with these kinds of carbys always smell like fuel.

The carb should come with instructions showing which port does what. I know the one up on the drivers side is for vac advance, as the port goes just above the throttle blade when at idle. When the blade opens slightly, the port is now below the throttle blade and supplies vacuum to the dizzy.

The others are all for vacuum accessories that can just be plugged. If you have everything else already running off the manifold tees, these ports are not needed. Holley just puts them there as some manifolds aren't drilled for all that bullshit and they need to allow for that.

The only full-time vac supply you should need is for PCV, brake booster and cabin heater/vent controls.

Carbon canister should just vent to the air filter or somewhere near the opening of the carby. Some emissions Holleys have an extra fitting out the top of the bowls to also connect to vac, but when running these vent the canister plus the bowls down through the carby. Yours probably doesn't have that though.

Don't hook the cannister up to vacuum, you'll get the engine sucking excessive fuel vapours from the tank (messing up your mixture) and sometimes even raw fuel if it happens to slosh up into the vent lines on top of the tank. Don't ask how I found this out.

Hey guys got the carb on just waiting for a few more things to arrive. Ive already hooked up the pcv to the base plate & now have just 3 hoses left 2 from the charcoal cannister & 1 from vac advance on the dizzy. There are 4 ports on the carb 1 at the back 1 on the side & 2 at the front underneath. Can i put the 3 hose's where ever they will reach on the ports?
