I am currently maintaining my Toro 25cc String Trimmer and noticed a lot of carbon and oil buildup in the spark plug. According to the manual it will take RCJ4 and RCJ6Y. Currently it has an RCJ4 spark plug to it.
If I use RCJ6Y will that eliminate the carbon and oil buildup? In comparison, I have 2 other string trimmers and the spark plugs for both have small amount of carbon and no oil on the spark plug tips (when removed). thanks
EDIT: According to my online research on HEAT RANGE
RCJ4 is COLD
RCJ6Y is slightly HOTTER
