LBWND;

What mixture are you running in that LB? I have gone synthetic to about 40:1 -maybe a tad leaner but that's the ballpark I aim for now. Made a big difference in oil residue and crap in the carb. Is your motor skipping or mis-firing? I'm thinking you are passing 32:1 rich fuel through the compression chamber. It's either that or a fuel leak somewhere, and I'd investigate your carb mix setting. After that checking, we are back to looking at Spark plug and Ignition coil. You'll get it! These machines are like Swiss watches. They need a bit of TLC, but when they are wound correctly, man, they hum!

Keep us posted.

BTW, I bought a replacement coil on Amazon for $19.95 DELIVERED! It works fantastic. No issues at all, and 1/5th the price of the OEM coil at $100. If you do replace the coil, check Amazon before you spend big bucks.... unless you are the kind of guy that absolutely has to have OEM and won't do Chinese coils. Me? I like saving the money AS LONG AS the part works well. Sometimes a new coil, with new spark plug can work wonders.

Man, that really sucks.

Your lower crank seal blew, and you just replaced it last year? Did you replace it or a dealer?

Pretty much and yes I did it and it was hard but I got it in.

Ouch.

I replaced mine last summer. Used a PVC Pipe just the size of the crack diameter to press it in. Easy with the pipe.
