PJs Posted May 5, 2020 Report Share Posted May 5, 2020 Just bought a 1966 tr4a and one of the su float chambers is leaking. Is there an easy fix Quote Link to post Share on other sites
RobH Posted May 5, 2020 Report Share Posted May 5, 2020 (edited) Welcome to the forum 'PJ' - do you have a name? It depends where the leak is and what type the carbs are (H or HS). If it is from the overflow pipe then the float valve probably isn't shutting off properly. If it's from the lid you may need a new sealing gasket. If it is from the base then the sealing washers probably need replacing. All fairly easy to do.

ChrisR-4A Posted May 5, 2020 Report Share Posted May 5, 2020 (edited) Hi PJ, if the float chamber is flooding due to dirt under the needle shut off valve then check the glass bowl and filter on the fuel pump for debris. If there's some present then remove and clean both float Chambers, check needle valves are closing and sealing. Also in case debris is coming from fuel tank to keep the car running fit an inline fuel filter, mine came from Robsport but many outlets sell similar.
