Re: Slow return to tickoverThanks for the input, after some further investigation this turned out to be a side effect of the ignition timing being off. I think because the ignition timing was off (retarded) I had tweaked the carb setting to get it to tick-over at a reasonable speed. After re-timing the ignition I needed to ma...
