Jane (1937 Opal Tourer) has just completed a full bottom up engine rebuild. Rebore, replace every nut, bolt, stud and gasket. Looks beautiful.
But she just won't go properly. Compression OK, starts fine, turns over sweetly, firing neatly on all 4 cylinders. Take her on the road and seems OK to start with, 2nd gear and we're gradually moving forward. 3rd gear and we seem to have reached a limit. Any slight incline or change up to 4th and its reached its limit. Just won't go any faster. Probably doing about 15-20mph (Speedo not working). Then we get backfiring from Carb., and a we build up a snake of traffic behind us.
Does the above description of behaviour suggest anythingh to any of you experts out there?
So far, we have checked
What next?

So far, we have checked
- Plugs all OK
- Carb has been tested, adjusted all OK
- Running with new Accuspark electronic distributor
- New coil
- All valves seem smooth and tick over sweetly.
What next?
