Hello,
Looking at a boat with a BF90A on it. When I went to compression test it the readings were from cylinder 1 through 4 (bottom) 160, 171, 170, 140.
There was also gas coming out of the bottom cylinder carburetor. These two issues pointed to the valve thrash in that cylinder being two small.
I adjusted the valve thrash and now the compression is 1-4 170, 176, 176, 160 and there is no issues with the carburetor. Do these value look good?
