My Ruby is in frequent use often covering 40 miles a day. Recently I noticed it was hesitant under load, normally towards the end of the 20-mile daily commute, sometimes popping on the overrun. It has gradually got worse and now fluffs /splutters between gear changes and struggles on hills. The first 5 miles of the journey are fine but this is gradually decreasing. Starts ok and idles fine, picks up from idle without hesitation runs well under minimal load.
I have changed the coil, condenser and rotor arm. Checked the points gap, checked battery voltage (6.4v). Plug leads are about 3 years old. Changed the exhaust manifold and inlet manifold gaskets, lagged the exhaust pipe, made a heat shield for the carb, cleaned the bowl, cleaned the emulsion block and checked the jets. Petrol is coming through clean and the tank has never had sealant in it. I've tried petrol from 2 different garages.
Each time out it gets slightly worse. What have I missed? Beginning to wonder if it could be a leaking head gasket? Any ideas appreciated.
