Not a good idea using chlorinated brake cleaner where it can be combusted such as testing for vacuum leaks, or cleaning metal before welding. When it burns it produces a deadly nerve gas that will permanently incapacitate with just a small whiff or two. We are talking brain damage, nerve damage, and death if enough of the combustion products are inhaled; this gas in not much different than was used during WWI. Use water, or carburetor cleaner when looking for vacuum leaks.

thanks, one more question about 1920

what about choke, throttle and kickdown...same as 1945?

this is what I want right
