I did this by running with knackered carbs! It pulled great from 1000 to
2000 revs and dropped right off by 3000.
Now I've recon'd the carbs I *seem* to have less low-end grunt (though
that's maybe because I've got power higher up now). Strangely, I seem to
have a dead spot around 3500. If I floor it it pulls happily up to 4000
then behaves well at these higher revs. Any ideas? Also experienced some
popping from the exhaust when gradually slowing down from about 3500 revs.
