Another new (1982) Honda Express project (3rd on this summer). 6mm nuts holding muffler pipe to cylinder really rusted, was able to get one off with a lot of penetrating oil and slowly loosening, tightening, (chasing threads). Second one snapped off. I did not take off muffler yet, so don't know how much I'm left with to "grab" on to.
I see from parts diagrams that it's a 6mm stud and still available - so whats the best way to proceed? Heat and vice grips and hope it breaks loose? Drill and easy-out or drill out and retap? Or???
Thanks in advance,
