I didn't see an air cleaner for the carb? Is a dusty runway bad for the engine? Thanks again
To answer your second question..........................YES, dust is very bad for your engine. If you must fly off a dusty runway, certainly look into an air filter for your carb. There are tons of them out there. Here is a link to just one.
