Moke won't start when hot
« on: December 18, 2018, 08:39:15 PM »
Hi guy's,  my Moke starts first time every time in the morning when cold but soon as I go for a drive more than 10 mins when I guess the motor heats up, it wont start again for at least an hour till it cools down.  Any ideas?   The motor has not over heated, it's just hot. 

Thanks.

Hi, do you use the choke to start when it’s cold?
Does it fire at all when you try and start it when warm?
Is the coil really hot when the car is warm?

Hi, I never use the choke because I live in Nth QLD.  It doesn't seem to fire when hot but it still turns over very fast.  I guess the coil is pretty warm, everything in the engine bay is to hot to touch.

Thanks

Hi, I wonder if it’s just too rich.
When you get the Moke running for a bit, try pushing the carbie piston lifting pin that’s under the piston body on the left side( looking from the front). If the engine idle races a bit, it’s rich.
Adjusting the mixture screw up ( anticlockwise) will lean out the mixture.
Not saying this is definately the cause, just something that might cause it.

Hi,

and while you are under there fiddling with HP's suggestion, see if the choke is not stuck with the jet tube locked down somehow. Sometimes just pushing the jet tube back up into the carby is all that is required.

If you have a waxstat jet tube, that is the one with the big metal lump with a nut on the bottom, it could be the internals have failed and you are flooding it.

If you have an electric fuel pump on it, what happens if you turn the pump on for about a minute and then try to start the Moke?
