Would changing the compression ratio change the heat range of the correct plug?  What would be recommended for a 140 engine with a CR of 9.25:1? 
================================================================================================
Everything can change the need for different heat ranges!!   You have to read the plugs after 100 miles...


I recommend;
NGK  #BR7HS    ITEM #  NGK1099, a cooler plug  than recommended for 95/110 hp  engines...
 NGK 1098 BR7HS-10 Standard Plug

SKU: #BR7HS-10
ITEM : # NGK1098
