MikeF Posted August 11, 2019 Report Share Posted August 11, 2019 I have petrol leaking from the bottom of my NO 1 SU 878 H6 carb. It appears to be coming from the bottom of the bolt assembly holding dashpot next to the jet. (this is the lowest point of the carb so may originate elsewhere. The leak drips till the dashpot is empty, the engine does not need to be running. Priming the carbs by hand at the pump refills the pot which cuts off effectively when full. The bolt is tight. I think I need to replace the washers in the assembly - or do I? Can this job be done without removing carb? Any tips thought welcome! Mike Quote Link to post Share on other sites
BlueTR3A-5EKT Posted August 11, 2019 Report Share Posted August 11, 2019 (edited) Yes a gasket pack would probably fix it. https://sucarb.co.uk/carburettor-kits/gasket-sets/h-type.html Do not forget the spanner sizing may be BSF/BSW if you feel the ring spanner is sloppy and at risk of rounding the hexagon off. Once the air cleaners are off the access is quite good. No real need to remove the carbs. Cheers Peter W Edited August 11, 2019 by BlueTR3A-5EKT Quote Link to post Share on other sites
