Question. I am currently using the #4, however I was wondering if this is the correct plug. I did lean out the carb recently to compensate for the higher altitude I moved from sealevel to 5000' , I checked the plug and the color seems to be ok. #2, #3, #4 My understanding is #4 will be a colder plug ? Thanks any info would be great. Jeff |
