Standard 6 Exhaust/Overheating- Holden Body

[hidden_hunter]

still working on it, been flat out at work and waiting on parts to come from the U.S :/

ended up getting a new belt from bobs that is about 4" shorter than the one that was on the car. There was also a lot of scale in the cooling system but the main parts seem to be functioning ok so I'm thinking the overheating was the result of compounding problems

after many (manny) hours, it's going again. We replaced any suspect gaskets down to the head gasket and have done a quick tune but its still running a bit rich. After a few adjustments, it now starts within about 1-2 seconds of tapping the starter

Heat comes up nicely after a couple of minutes and we only seem to have a few drips of water from old radiator hose (which I'll be replacing after a rad flush), no petrol leaks from the carb after replacing all the gaskets and o-rings/washers and no oil leaking from the motor either.

The overheating seemed to be caused by a couple of things, fan belt was way too long so the fan was jammed up. Scale had built up all through the cooling system so there was no flow, all cleaned through by hand when we replaced the head gasket so now there is a good flow of water through the rad. What sort of pressure should we be seeing on the gauge? the one on the car looks aftermarket and kinda crappy but it would be good to have a baseline.

Got a new section of exhaust made up to replace the broken off piece, which thankfully could still be used as a template

Lots of little fiddly jobs as well (the hand switch for the lights at the bottom of the column!!!!) but inching closer to getting it back on the road. A few electrical things to sort out (like the horn and head lights) and the accelerator not having enough travel in the pedal (can open the throttle and close it fully) which makes it next to impossible to move without stalling.

And as promised, a video of it running!

Thanks for the video, Looks like you,ve got a lovely car there and the engine sounds great . To adjust the carby, turn the air screw so the end is level with the end of the ratchet. Close the fuel adjustment wheel at the bottom, then open one turn till the notch is facing the guide post. A leaner or richer mixture is obtained by slight adjustments of the air screw. Remove your floor boards so you can see the accelerator linkages better to make adjustments.

Thanks mate, I'll give that a shot on the weekend - it's a bit chuggy at the moment would you dial it out the same way?
