AarhusTr6 Posted August 25, 2024 Report Share Posted August 25, 2024 Hi picture shows two plugs almost new with about 300 miles on them. left is piston 6 right piston 1. I guess 6 is kinda okay whilst 1 is too rich. who would agree or give further comment ? Richard Quote Link to post Share on other sites
BlueTR3A-5EKT Posted August 25, 2024 Report Share Posted August 25, 2024 This is a carb engine? One flat leaner on the front carb. (1) One flat richer on the rear carb (6) Then try and check again. Confirm there is oil in the dash pot dampers Quote Link to post Share on other sites

CK's TR6 Posted August 25, 2024 Report Share Posted August 25, 2024 CW enrichen, CCW lean. assuming you have adjustable needles and assuming the adjuster hasn't been backed all the way out already. Methinks I would turn CW to the stop, counting "flats". There is about 1 3/4 turn before disengagement. However!, the design of the manifold doesn't ensure even distribution of the mixture to the corresponding 3 cylinders of each carb. I would compare 1, 2, 3 to each other (kinda do the average of the 3) to 4, 5, 6 (average of those 3). Quote Link to post Share on other sites
AarhusTr6 Posted August 26, 2024 Author Report Share Posted August 26, 2024 Thanks - I did not plan to take the caps off and only use it all so thank you for the education on the hexagon. And good thinking CK on pulling all plugs! Quote Link to post Share on other sites
BlueTR3A-5EKT Posted August 26, 2024 Report Share Posted August 26, 2024 …and you do have access to a needle adjusting tool? https://www.ebay.co.uk/itm/233216091197?mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338757644&toolid=20006&customid=c53c23b63267434f4e89746966381d09 Quote Link to post Share on other sites
