I hope someone on the list can offer an explanation and solution to a problem
I've never seen before.
My TR4A is running rich withg sooty black plugs on cylinders 2 and 3, but
perfect coffee with triple cream colour on 1 and 4. This can't be carb
adjustment since either the front or back pair should be affected. I also
don't think it's oil since the valves and guides are nearly new, about 3,000
miles and the exhaust does not seem smokey.
I had the head off over the winter, the problem was obvious from the colour of
the valves, and I noticed a couple of stripped studs on the exhaust header,
which I replaced and tightened up properly, but there's no improvement.
Any insights or suggestions welcomed. Thanks.
Simon, WOFTAM Racing.
