Black Spark Plug
Ok, so for a little Christmas project this year I'm probably going to tear down my crf70. When I got it the plug was black and a little oily, so I changed the oil and put a new one in and adjusted the valves. It has a hard time starting in the cold (even at 60 degrees) so I checked the plug again and its black and oily again. Wondering if it is actually the rings before I start tearing into the engine. I probably need to clean the carb up so maybe that will help with the starting. After I put the new plug in earlier this year it would start up just fine even in the cold but after the oil and shit gets on the plug it can't really get a good enough spark, right?
If I have to do some engine stuff I would rather try it on this little 70 before I might have to do it on either of my bigger bikes. Part of why I got the thing was to screw around with it. Is there another way to tell if the rings are bad?
