26VA carb adjustment

That makes sense, and I can understand why it would be more evident on idle. What puzzles me is why mine appears to be running rich, and why under very light load, especially as the jets are the ones that were in it before. Time will tell if it is tightness but I can't say I've experienced anything similar with previous re-bores.

I might run it along a long flat road and check the plug colour to see if that gives me any clues.
