I'd like to keep my 71 Commando as stock as possible so I've still got the original Amals on board. I've replaced the jets and needles with new, authentic AMAL parts but the left side is still running rich. I can't get 30 miles out of it before I have to change the plugs.
Other note is the idle is high at 1750 rpm with idle screw fully out.
Where/what else might be causing this? Float bowl level appears correct. I would have thought wear on the barrel would result in a lean mixture. A new set of AMALS seems a little radical and expensive.
Baffled.
