TR Rob Posted November 2, 2023 Report Share Posted November 2, 2023 I have being doing a bit of work synchronising the SU carbs on my TR3A , first time and with some success ! However I have found that the throttle tends to stick on return at about 1000/1100 rpm. If I manually move the throttle linkage it immediately settles at about 800rpm, the same happens if I pull up the throttle pedal. I have noticed that there is no spring (15 below) on the throttle lever/quadrant. I am sure this will solve the problem and I am sure there is a location for the spring on the lever, (hole) but my question is where does the other end locate ? Hopefully someone on here can tell me and perhaps show a picture. Thanks Quote Link to post Share on other sites
rcreweread Posted November 2, 2023 Report Share Posted November 2, 2023 Rob - there should be a small rectangular tag spot welded to the bulkhead below the pivot arc of the throttle lever coming through the bulkhead - it has a small hole in it which the end of the spring locates in - not sure if there is a different spring arrangement for LHD cars as there is an extension rod which comes across from the nearside.

RobH Posted November 2, 2023 Report Share Posted November 2, 2023 Sorry this is a bit out of focus Rob, but on my car there is a small tab with a hole at the front edge of the footwell [arrowed] Quote Link to post Share on other sites
TR Rob Posted November 2, 2023 Author Report Share Posted November 2, 2023 Thanks for the replies, will have a good look tomorrow in the places indicated. Quote Link to post Share on other sites
TR Rob Posted November 3, 2023 Author Report Share Posted November 3, 2023 Had a good look this morning and to my relief I found the “small” tag on the bulkhead and after cleaning some Road grime off the lever a hole in the lever. Have ordered a spring, just need to fit it. I imagine that it will be a bit of ‘fun’ ! Quote Link to post Share on other sites

BlueTR3A-5EKT Posted November 3, 2023 Report Share Posted November 3, 2023 You might try to fashion something like this spring hook out of a wire coat hanger Quote Link to post Share on other sites
