Spark plugs?
Spark plugs?
Really appreciate all the help.
Governor looks ok but frankly I probably wouldn’t recognise if it didn’t.
Ran it tonight. Idles fine but garage smells of gases quite heavily so it’s obviosly rich.
It’s only on one side as it runs fine on one side if the plug cap is off and won’t run on the other if the cap is off.
Interestingly my temp sensor shows it much hotter on the “good” side than the other.
About 85k miles. It’s gassing out really heavily in the garage when run for a few minutes.
I hadn't seen this post. This then narrows it down to one side and a fuel problem. You could try swapping the bits like float control needle and seat, metering needle and clips etc. from the good side to the bad side and see what happens. If it's running rich on the cool side that doesn't surprise me as the excess fuel is serving to cool it.
Or not being ignited because of an electrical problem!
Well it was Rob Farmer who put me on the right lines.
Checked the governor with the cover off and sparks flying everywhere! The points were arcing out and little adjustment stopped that.
Then started from scratch with the carbs.Re adjusted the throttle cables, stated with each mixture screw even, got the ticker correct and equal on each pot and the sorted out the mixture. Re-adjusted the ticker and job done. Replaced diaphragms, inlet rubbers, throttle springs, leads plugs, coils, condenser, governor springs, choke bodies and to be fair they all need doing as they were old.
Something so bloody simple............still all the ignition parts are now new so the re-bore it has just had its good for another 47 years.
Thanks everybody
