I used brake clean in my old mculloch super pro 60 to clean it up when i first got it. However after a week i went to take it apart and noticed the rubber hoses were now rotted and cracked. They werent before and my only conclusion was that it was the brake clean. I dont use it any more around rubber and i only use carb cleaner when checking for intake leaks.I use Brake Clean for cleaning my old barn find saws. It goes on sale here , buy one, get one free, so comes to about $2.50 a can. For a new, in use saw, I just use the compressor to blow them out. The Brake Clean is pretty aggressive, and will cut the paint off some old saws. But, it will clean the old greasy oil soaked saw dust out of the fins on an engine quick. It doesn't hurt the plastic on Stihls. I grew up in the tree removal business, have been out of it for 35 years and still buy a saw every other week or so. Much cheaper than old cars!
A side note, carb cleaner with bleach when used on an intake creates a very very toxic gas when the engine is running! I had an air cleaner soaked in brake clean and fired up my pressure washer to dry it out and i thought i was gonna pass out from the exhausst! This aas outside too!
