Howard 350 with the Kohler K141T engine fitted . Starts from cold OK runs, but eventually looses power, misfires bang and pops . Checked fuel and carb(Carb swapped from another engine . Wondering if the coil or condenser could be failing when hot or under load . Checked points .
Condenser is located by the coil, inside the flywheel. This is an early engine I guess as my others have the condenser mounted close to the points externally.
Tried new plug, checked for kill switch wires shorting , plus checked all coil and condenser wiring . Electricall condenser seems OK as far as I can tell in as much as it works enough to start the thing . Tried running engine with the points cover removed to make sure that is not causing a short
This particular condenser is obsolete . I am thing of fitting a new condenser re locating it to the normal location near the points .
I do have an electronic ignition kit but I want to make sure the ignition system is OK before I fit it
Any ideas ?
