Verify the plug wires are connected correctly. Look here: http://autorepair.about.com/library/firing_orders/bl-fo-1312.htm It can also be a bad spark plug, or plug wire. A burnt valve or blown head gasket is another possibility. A weak injector on that cylinder is possible. A compression check is in order if the ignition system is found to be OK. This will detect a blown gasket or burnt valve.
B & S plug 499730 is replaced by B&S 5062 (standard) or B&S 5062H (Extended Life / Platinum) Each one has a heat rating of 19, so a Champion J19LM works fine too, as does Oregon 77-301-1 or Wagner 66082 or Bosche W9EO. These are lawn mower spark plugs. I use the Platinum one myself. Lasts longer. Double the cost, but $6 compared to $3; that sort of thing, so relatively cheap and no headaches while mowing.
from factory they offered a Pontiac 400 w/ 4-speed or the Olds 403. 301 was also available.
