Sorry to be a nuisance. Don't suppose you know the gap for a spark plug Champion L82C 20hp Chrysler. Fuel now flow into carb but still reluctant to start
Should run ok with .025" or 6 mm gap but if a weak spark because it hasn't run for sometime I'd reduce it to .018 - .020" or around 5mm, maybe less. Put a little fuel down the plug holes to get it firing and make sure the choke is working properly.
