TR Rob Posted November 23, 2023 Report Share Posted November 23, 2023 Not sure of the merits of one of these, but having spent many years away from car maintenance ( oh, the joy of fully maintained company cars !) I was thinking one of these might be handy to have regarding tuning of carbs. etc Based in Hampshire Link to post Share on other sites
Lebro Posted November 23, 2023 Report Share Posted November 23, 2023 Very handy, I use 4 of them so I can see all cylinders at once. Usually can be found on Ebay Bob Link to post Share on other sites
TR Rob Posted November 23, 2023 Author Report Share Posted November 23, 2023 Wow….I thought one would be OK, and I can see the point of two, as one carburettor serves a bank of two cylinders. Not sure how you get a difference in mixture between two cylinders being served by one carburettor ? Link to post Share on other sites
Motorsport Mickey Posted November 23, 2023 Report Share Posted November 23, 2023 Air leak between manifold and the individual ports against the head or the carb. Mick Richards Link to post Share on other sites

TR Rob Posted November 25, 2023 Author Report Share Posted November 25, 2023 (edited) Managed to get a full kit and instructions in excellent condition off EBay. I presume it is fairly straight forward to set up. However, as I have never used one before are there any tips I should be aware of in setting and adjusting the SU carbs. on my TR3a ? Will also post in TR3A section Edited November 25, 2023 by TR Rob Addition Link to post Share on other sites
Lebro Posted November 26, 2023 Report Share Posted November 26, 2023 You are aiming for a blue flame , just on the edge of turning yellow. Solid blue is too lean, solid yellow is too rich. Don't forget to clean the glass bit after every use. Bob Link to post Share on other sites
