Re: compression of a 45hp 1985 Chrysler ??

Compression testers will all read different.Mine was around $100 and it reads 150# on my Force 85s. AS long as it even and no big difference more than 10-15#per cylinder.
You should have about 150# but don't get upset if it reads less.Under 100# I'd get another tester and see if the results are the same.J
