The coil and condenser made no difference. The problem was the main jet which I had drilled out too much so the engine was running too rich. It runs much better with a standard jet. The only thing I've not figured out yet is why the timing needs to be 15 degrees advanced but it seems to run...

I've just put the standard 1108cc main jet back in as the car ran too rich on the jet I drilled out. If the car is running OK then the existing jet us probably fine.

I've been troubleshooting a weak spark. The points and ignition leads are new and everything else is old. I've fitted a new rotor arm and no longer get zapped touching the distributor cap, and the engine will tolerate a little choke now, but it's still not right. New distributor cap arriving...

I fitted the Zenith 28IF carburettor. Now strange things are happening and the car won't run well. I did take the distributor apart (and replace the head gasket) over the last couple of days and but I think the problem might be a very weak spark that the new carb has shown up. The...

I went out to change a carburettor and went a bit too far. :laughing: There was froth in the expansion bottle which I guessed was combustion gas blowing into the coolant through the head gasket. There was no water in the oil. Sure enough the head gasket was damaged. I've not seen one fail...

Brilliant. I'll fit a 28IF and hopefully the Rodeo will go a little faster.

Turns out the manual says Zenith 28IF carbs were sometimes fitted to 680 engines and it lists the jet sizes. That somewhat answers my own question. :ashamed: I'll give it a try. The Rodeo group on Facebook say their cars can go 10km/h faster than mine so some performance tuning is needed.

My Rodeo is too slow. It has a 747cc engine and really bad aerodynamics and the maximum speed is under 80km/h. It has trouble holding 4th gear on the slightest incline. The carburettor is a Solex 22-26 which I think means 22mm throat. That was only a 747cc option and it's going to be one...

Do you mean the suspension mounting bracket? It doesn't look so bad. Wouldn't be a bad idea to brush something oily on there to slow down any deterioration. A normal paint probably won't do you any favours as there are so many seams and bits you can't get to but painting something oil like...

I prefer 145/80 13. My fleet is running Uniroyal Rain Expert 3.

I always used to open the door a little then give it a pull upwards to bend the hinge back to the right place.

A bit more progress today. Speedo is working again with a new needle. I've been trying to improve the performance as the top speed is only 80km/h. It's only a 747cc engine but I was hoping for a bit more. Old fuel won't be helping as it runs best well off the factory recommended timing...

I've been calibrating a speedo against the sat nav today. This Veglia speedo seems accurate when the needle is placed about halfway between the bottom stop and the bottom of the speedo case. It can be bent a little to get it back past the stop. Well worth checking it against the sat nav...

Oh heck - bubbly froth in the expansion bottle. I've ordered a head gasket kit. It probably is the head gasket pushing combustion gasses into the water but I've got a test - let the car cool overnight and remove the expansion bottle cap the next morning. If it hisses then there is more stuff...

@mr-reno-139 Thanks for the Ornella brake video. I did the Rodeo brakes 8 years ago so they will have had a chance to get stuck. They seem better today and the hubs were cold when I checked. I'll try adjusting again as @Piet suggested. I'll need to adjust the handbrake too - I've got the...

The Rodeo made it to Tesco about 5 miles away on it's second attempt and I put some petrol in to see if the fuel gauge works. It doesn't and I think it's the sender. The speedometer doesn't work either - it gets stuck because of a bent needle. There is an uncomfortable vibration in the...

I think I've found a fix for the issue I was having. I've replaced the (aftermarket) coil with a spare and it will tolerate choke when cold now. Resistance in the old coil was a bit low in the secondary winding so I think something has gone wrong in there. The R4 coil measures 3 ohms...

Sounds like the same one. I had to replace the top bolt with an allen bolt because there wasn't room for a socket behind the solenoid. A 5 year life isn't good - they are a pain to fit in LHD cars.

Claude has never been very good at starting and I assumed that was because the fuel drained back past the pump after he had been sitting for a while. The fuel filter stays full with the new fuel pump so that's not it. And the petrol is new. The engine runs perfectly once it is going so it's...

The trimmer did a brilliant job. They are 1972 van seats with the the proper seat base and the deck chair back. They are very comfortable but at first my legs didn't fit under the steering wheel. The base foam is original and fortunately they settled quickly. It felt like summer today...
