b40rt Posted May 16, 2010 Author Report Share Posted May 16, 2010 Thanks to everyone who contributed. I have now done 2 club trials and the pre 65 2 day - all on 1 plug. A BPR5ES. I did get a supply of BP4ES (equivalent) plugs but never had to use them, as I try only to change one thing at a time. The solution, as jon v8 suggested, was ignition - new coil and HT lead. Now runs really well, and the carb adjusters from Billet Parts makes it so much easier. Thanks again Ross Quote Link to comment Share on other sites More sharing options...
