Today ended a little bit better than where I was mid-afternoon but on the whole not a great day. So what’s happened? Well Marvin for some weird reason has started to play up again. I am not 100% sure what the problem is but I suspect its the carburettor. (Oh no not another one playing up) .
I knew the carb was weeping a small amount of fuel from the accelerator pump, but that aside yesterday he was driving fine. This morning I did a swap of the rocker cover and a trial fit of the alloy rocker cover (all looks good there), But in order to fit the rocker cover I had to remove the carb and manifold. After resealing it all back down and reattaching all the bits and bods, Marvin would start but sounded like he was on two or three cylinders? He would only run is I kept blipping the throttle, as soon as I attempted to hold the revs and any fixed level the engine would die.
I also noted that If I placed my hand over the top of the carb to block the air flow he would run smoother, and the worst bit was if I pulled the choke out the engine was scream away at high revs even with the throttle closed? Needless to say I took it all off again and made sure it was all correctly fitted to the manifold with no air leaks, and similarly removed and made sure the manifold was sealed correctly and bolted down.
I checked the HT leads and rotor cap / arm (electronic ignition so no points to worry about) , restarted the engine exactly the same…. I am a bit lost with this, nothing makes sense.. I had this with the Webber not two weeks ago, one day drives perfect the next day its farts and bangs fuel comes flooding out the carb then after leaving it a night it drives fine again? That’s why I changed it back to the Solex… now a similar issues has risen up again?
I popped over to the garage and collected up all the old Solex crabs I could find and got one good accelerator pump gasket out of them. I then replaced the one on the car. I also popped the top of the carb off, the main jets and everything else are clean and appear un-blocked, the main float bowl was full of clean looking fuel. I have a new fuel filter in the car before the pump so its clean fuel coming into the carburettor? I retried the car and this has helped a small amount in that the car now appears to be running on all 4 cylinders and sounds smoother, but this inability to stay alive has got me confused, I can rev it up but as soon as I stop pumping the throttle the engine dies, unless I pull the choke out and then the engine revs its head off with zero throttle?
So I put Marvin aside and thought I should look at the Escort, as the front under-tray has come loose and hanging down, so low that it now grounds on speed-bumps.. Several hours later I have the tray sort of back on, but all the fixings were rusted and or broken so I have had to use a load of vivas nuts and bolts to jury rig it up. More annoying is that both front tyres are bald as a baby’s bum on the inside edges, so much so I will need tyres tomorrow. I am annoyed as the tracking as out but having taken it to ATS 8 months ago to be re tracked and only having done 6k miles I find the brand new tyres bald !!!!
So not a great day, but at least the everyday car is still running, time for me to find a new car this one is on last legs literally! I will be getting parts worn tyres tomorrow if I can as this runs out of MOT in a few months and will never pass another. I don’t see why I should waste good cash on this old bus.
