Hello again. I had my 33 RP out last week, after fitting a H1 SU carb. It ran quite well, with, I believe, a bit more oomph.But it did seem quite thirsty, and I could smell petrol in the exhaust fumes. Now I believed I had it set up right, new jet kit, AN needle, but it still burns rich. There was oil in the dashpot, no spring, and the weight on the dashpot damper had been turned down to give 160g. So I removed the dashpot oil, a bit more power, but still rich. So I refitted the spring, (no colour visible) runs well, but still runs rich, but ticks over well. I may try a weaker needle. Any other ideas?
