Have been driving this around and its been doing just fine. Fuel consumption is pretty abysmal atm though. Getting about 20L/100 which im putting down to the carb not being tuned. The exhaust is also pretty well blocked up and not a whole lot of air comes out the back but its serviceable and there are a few competing priorities so will get to that when I can. On thursday I followed a guide to set the cruise/idle mix and its idling way smoother and bottom end pickup is much better. The transition from primary to secondary is less harsh and it pulls (as hard as an Astron can) to 5k which it didnt before. Gave it a run out on a private road and saw 140km/h on the speedo before I let off which was much higher than the 110 I saw when i first did the swap. Also added about 4 degrees of timing which it has taken to well.
It has been fun and quite interesting working on something with a carby. All my other old cars have some version of EFI and this is my first carby car ive owned that I actually use that isnt just a paddock basher.
