I still have the exact issue.

Bigdog did you ever figure out what was going on? I think I am going to clean my carb again...

 

This thread has greay hair.LOL

 

I just noticed hehe..

 

I had same exact problem with my 80. These carbs are so small that the carb/jets need to be cleaned regularly. Even after cleaning my carb and checking holes in pilot and main the machine still doesn't want to start. Clean air filter, clean carb, removed oil injection system and installed block off plate.

 

"I had same exact problem"
What's that??? resurecting a year and a half old thread..
BAHAHAHAHAHA
