Spark Plug question
Does anyone know the difference between trailing and leading spark plugs? I don't know which ones to buy? Do I need to buy four of each?

I use this little memory aid:

L = leading plugs, go in the LOWER plug holes

T = trailing plugs, go in the TOP plug holes.

4 total.

2 leading - hotter plug (BUREQ7)
2 trailing - colder plug (BUREQ9)

V Belts
Do you guys also know if changing the 4 V belts is an easy process or a lot of removal of parts?
