Ok, I removed the spark plug but can't seem to find any information on it. The manual doesn't even identify which plug they recommend. The information on the plug is
LG NANDI
F6TC
27100
I can't even find a LG cross reference chart. Since it doesn't have an "R" in the model number, I am guessing it isn't a resitor plug?
F6TC is the number to search for.
I am taking a swipe at this that your plug is non resistor.
One cross reference I found gave these as substitutes..
NGK, BP61S
Denso, W16EX-U
Champion, N11YC
Autolite, 54
Bosch, WR6DC
Autolite, 54 was superceded by 64 and Autolites cross reference matched F6TC to Autolite 63. Both 63 and 64 have the same thread, same reach, same heat range (IE MEDIUM) and are both resistor plugs.
Champion N11YC is non resistor but you can use RN11YC4 which is the resistor version, these are both identical thread and size and both are in the HOT heat range.
The others listed I didn't get a chance to research but if they don't have a "R" in the PN they most likely are not resistor plugs, but you might be able to find the resistor versions..
