I've got the old gasket out, cleaning surfaces now to prep for the new gasket.

Having a hard time getting some of the crud cleaned off. I've been using carb cleaner, but it's not getting everything off. Any suggestions for what to use instead of carb cleaner? I tried brake cleaner, and throttle body cleaner, neither did any better.

I don't have a garage, so I'm working outside. There's only a short window on days it's warm enough and not raining, so it's taking a long time to finish.

 

I know its an old tread , but in case somebody new has the same problem - .......I always use a scraper to remove gaskets and then some acetone to clean the lefotover , if any ...... cheap 1$ window scrapers with the standard 1,5 ? inch steel blades - they are widely available in packs of a 100....
