Re: 1098 engine starts, runs, cuts out, starts, runs....

Ppg is on the money! Check for spark immediately it stops. That will sort out, in a moment, whether it is ignition related or not. Carry a spare, known to be working, plug. It only takes a few seconds to remove a plug lead. If no spark, check for spark at the king lead. That will sort out if it is a...

Re: Which Loctite threadlock to use?

As Les, I would use spring washers in those applications. Don’t think I’ve had them come loose on either item - ever.

Re: Fitting failure of water temp sensor adaptor - what went wrong?

IIRC, most of these electrical temperature sensors are thermistors which change from somewhere between 2k and 200 Ohms (some may be only 600 Ohms cold?). So likely only needing a shunt or series resistor to make them compliant with the usual meters used for indication.

Re: Rebuilt 1275-running a bit "out of sorts"

it's losing water through the radiator cap. I believe this is because I have a 4lb cap, I will try a 7lb cap. I suspect there is more to it than 3psi will solve - if it is actually losing water. Water boils at 100 degrees Celsius at one atmosphere. 4psi above atmospheric pressure and it will boil a...

Re: Fitting an oil gauge.

It's fine to use on thread you don't want to undo again. But don't a lot of threaded fixings eventually need to come apart on a vehicle? An appropriate loctite (or similar) product would surely be better than risking breakage later? Wellseal is for sealing joints to prevent fluid leakage, not prima...

Re: Dwell angle vs points gap.

Did you adjust the timing, after changing the contact point gap? The dwell angle is simply the means to reach (near) saturation current in the coil at maximum engine speed. There are two requirements for the points when opening. First it must be fast enough to avoid sparking as the points open - thi...

It should be quite easy to check those threads with a set of thread gauges (or with a travelling microscope, if you have access to one).

Re: Starter solenoid on the way out

I, too, think you are OK with the wiring - but only “think”. I, too, strongly suspect the solenoid, as there is no ‘clunk’ reported when operating the key - if there was, and the starter did not work, the fault could be the solenoid (contacts dirty, burned or poorly adjusted) or the actual motor par...

Re: Noisy engine & lack of power at speed

Is the dizzy providing a spark? If not, the engine will never ever start - whatever angle you might be trying!

Trying to guess the correct setting is a good time waster - unless you know the timing is close (experience needed for that).

Was your ‘fellow Moggy enthusiast’ of no practical use?

Re: tube nut stuck

Tube nuts seem to be either male or female thread - if it is a female thread, cut/grind along the thread to remove any pressure on the thread. Even if brass, take care not to create any sparks when into steel unless any hole into the tank is securely sealed. Might be easier to ‘bite the bullet’ and ...

Re: Starter solenoid on the way out?

I know which I would be checking first. A length of wire with a couple of crimped connections is far cheaper (and easier to fit) than changing the starter motor unnecessarily. Supply starts at the ignition switch? Easy to check, less likely to be at fault but ..... would still have to be changed aft...

Re: Noisy engine & lack of power at speed

The effect of wrong clearances - no clearance will cause poor starting and soon destroy valves; too much and the valves will open later and close earlier, make a lot of mechanical noise with associated increased wear rates. I would not expect power to be truly awful unless really wide. Although set ...

Re: Starter solenoid on the way out?

So sorry to say but it does sound like the solenoid on the starter motor is going out.

Possibly, but there are checks to be made before jumping to conclusions. Like the supply to the solenoid.

You could use the starting handle for its designed use? Additionally you could wave it at the other plot holder (while explaining that you do, at least, have an alternative starting aid available if the starter fails to operate or if the battery state of charge is just insufficient to turn over the ...
