Thread: back up my math/ confirm some numbers

I'd like to thank all involved for this discussion.
I've been thinking since my motor rebuild, I've been getting very good fuel consumption for a V8 4wd. Since following this thread I think I might have a carby/ tune problem also. I'll get someone with more nouse than me to look at them.
I'll ask in a new post for people's recommendations of a carby magician in western Vic.

This is a great forum.

Have you got the mixture tool for the strombergs and a balancer, like an old crypton. Sounds like its just running lean. Is there any holes in the diaphragms and are there any wear marks on the seats?

this 28KM route for about 4

And after a guestimation balance

This 200KM route For 24L of unleaded


Atm I havent gone to any great lengths to get them perfect and I havent pulled them apart. Its low on power but getting better the carbs are now within an inch of mercury as opposed to the 9 that I started out at but I suspect that its not pulling enough vacuum Im out of time to do any in depth diagnosis, the plug I pulled to check its mix looked good but Ive only had it running for about 600K while Ive been playing with it setting the timing, idle stops, linkages and choke stop.

If it wont idle without choke then isn't it just running lean. If you have the mixture tool then its just a mater of screwing them anti-clockwise to richen them, then re-topping the dash pots with oil and test until sweet.

yes, assuming everything else is ok.

sometimes it idles like a swiss watch other it struggles even with about 1/4 choke on.

Im thinking its a combination of junk fuel, a diaphragm leak and dodgy cables.

whoever did the last work on it got it to idle by winding up the idle on the drivers side carby removing the throttle arm linkage and winding in the choke stop on the passangers side carby.


I have noticed that the pickup and flat spots are starting to go away as I get fresher fuel into the tank
