This 69 Johnson 9.5 is an old timer that I'm planning to mess around with, was told a year or two ago by a dealer that compression was low, on its last legs, don't bother with it, etc. I have a feeling they just didn't want to be bothered with it. Water pump seems good, with a good healthy stream from the tell tale, I think the impeller was replaced two years ago and it has seen light use since then.<br /><br />Engine will start, but is hard to start, lots of mucking around with the slow speed adjustment and choke. Once started and it gets warmed up, WOT is very slow until the slow speed adjustment is leaned out, then goes pretty well on a light 14-footer, although it doesn't have the oomph it used to.<br /><br />I decarbed it using one can of Mercury's engine tuner and got lots of smoke, but didn't really notice a difference in performance. Should I do it again? I really don't know if it's ever been decarbed before. No black stuff came out, just lots of white smoke.<br /><br />I have a Seloc manual and just wonder if someone could point me in a starting direction for making it easier to start and maybe not having to fool with the low speed adjustment so much to get it a little faster at WOT?<br /><br />Thanks.
