What about the car, how that going?

A little more work today and another discovery. For all you SU carb users that are having problems, this maybe one to watch out for.
I've been having issues with running rich while cruising and running lean during acceleration. I also noticed after a while that one carb piston would never drop at the same rate as the other (very slight difference). I had re-bushed the throttle shafts ad replaced the butterfly's, completed a full overhaul, tested piston springs, and weighed both pistons. Today I found dashpot had a drilling and the other didn't. Seems later SU's didn't run with a vent hole in the piston damper cap and the damper piston was internally vented. Although the dashpots have the external casting for the vent drilling, not all are drilled. All this meant one piston sat at a different height for the same throttle opening and also rose at a different rate under acceleration. Anyway I'm getting close, have got the jet seats within 003" height of each other and am starting to get close with the needle polishing to get the right profile. Any advice I can give to others having problems with SU's is to make the effort to fit a plug and play AFR meter. With out it you are totally guessing to what is happening throughout all running conditions.

Been a while but managed to get back to sorting a few issues with the FB. Finally sorted out my throttle linkage set up as it was very aggressive and didn't get full throttle. I've still retained the original throttle bar but now run a cable from that to the carby/s via two small pulleys that I knocked up out of aluminium stock. Also changed the carby throttle linkage to a progressive cam type that works with the cable. Very pleased now. The car is so much better to drive around in traffic and stop start work.

So which one are you taking to Tazzie ???

Just the EK hack ute. Need to keep on with putting some miles up on her before Perth. Still got a lot of other stuff to sort on the FB that I'm not happy with and I really want to get the new trim done at some stage. A two other projects have slowed me up a bit.

Another pleasing day today. Dragged the boat to Heyfield with the FB for a display at the Vintage Machinery Rally. Car was pretty boggy off the mark until you got some revs into it. Ended up fitting the heaviest piston spring (green) and an extra spring out of a ball bearing chamber SU into each carby. Very very happy now, pulls clean and still revs hard. Just some finite work with the ignition and carby needles and the engines done......finally.

A run in the wet for the Holden farewell cruise. A great day but bloody awful weather.

Slowly getting back into changing a few things...……………….these cars are neve done!
Swapped down to twin 1 1/2 Su's and did some rework to the throttle as I wasn't getting full throttle and it was touchy to operate at slow speed. It still uses all the standard throttle set up but now runs cable and rollers to a cam lever on the throttle spindle.
The carbies were later HIF Su's with emission set ups and the vacuum take off for the distributor advance is not in the correct spot for proper ported vacuum so that had to be redone. Removed all the carbon canister tubing, plugged and drilled out other ports, and bashed out another set of filter covers (Still to be polished). Annoyingly I will have to replace all of my vacuum tubing for the wipers and washers. The quality of rubber these days is crap.

nice - back in the shed now the footy season has finished ??? or is that still a touchy subject

Thanks Clay.

Very nice work Craig - the heater hose solution is really nice - might pinch that idea if that's OK - what did you use at the pump end?

Could the pipe fit in between the top rad hose and rocker cover?

Assume you use 3/4 pipe?

cheers
