that's what happened to my 5port yesterday, just not as dramatic. Just got done taking engine apart. was the inner seal in the crank case for the carb. And of course I am now trying to play parts locator. Looks like I will need mark from massive mods for help again. I emailed 22racer to see if he has anything but have not heard back from him. 22 if you read this I am looking for part#s or-0028 and or-0014. thanks in advance Rex.
