Hawk 250-Fouled Spark Plug
I'm at a total loss and need some help. I've been fouling spark plugs with my mikuni carb. I started with a 115 jet, went down to a 105. Still fouled the plug. Went down to a 100. Still fouled. Put in a 98. Same result.
Today, I swapped out the mikuni carb for the stock carb. Fouled the plug again. I opened up the air box to check the air filter, and the filter box and filter were wet. It appeared to be oil? Plug is not wet. Just seems to instantly turn black. I have no idea why I'm fouling plugs and experiencing major engine hesitation through all RPMs, save idle. Can anyone tell me what's going on? |
