A few bits and pieces going on in slow time, but I thought I would bite the bullet and rebuild the rather rare Weber 36 DCA 5/250. Well I ended up rebuilding my spare is the one on the car (which ran) was in a worse condition than I had anticipated. So after fitting the spare refurbed carb the car fired up straight away and apart from a few tweaks ran sweetly.
As the car was up to temperature I thought I would steel my self and do a hot compression test:
Cyl 1 160, Cyl2 165, Cyl 3 110, Cyl4 170.
All plugs looked the same nice tan electrodes and slightly sooty around the edge (not surprising having just run on choke to start...).
I shot some oil into Cyl3 and didn't get a better reading (well 120). So think one of the valves isn't sealing well. Bear in mind this is a Volumex (CR 7:1) I am not too worried at the mo.
