I thought I'd better just update my blog. I've had a busy few weeks working on the car. Firstly, I took the carbs off and rebuit them with new throttle shafts. I took time with the Dremel to thin them out to about half the normal thickness (as recommebed by Kas Kastner and others) but I didn't bother thinning the butterflies for the tiny difference they'd make.
With it all refitted to the car I set about setting the carbs up. One of the most important things to get right is the same amount of air must be sucked in by each carb. In order to check that you need a carb balancer. So after trying out a Gunson Carbtuner and finding out it was absolute crap I got on eBay and bought a decent flowmeter from Eurocarb (who I can highly recommend for their excellent customer service).
So with balance set using the flow meter and mixture set using a Gunson Colourtune it was all good and sounding better than ever. Unfortunatly whilst it revs beautifully and cleanly on the drive it's a bit stuttery on the road. I haven't got around to sorting yet but I will!
I've also been sorting out an unsightly rust scab that had been lurking around on the drivers side of the windscreen frame. I was pleasantly suprised to find no deep structural rust and can happily report that the area has been rust killered and primered and the top coat is drying as I write this. It's looking better already!
