Johnson Engine Issues ****HELP HELP

[waterdogMP]

I've already ordered the stuff I know it needs (plugs and the power pack) so It's a little late for that, lol. I'm going to pull the cylinder head tomorrow or sunday and take a look. I will try to take some pics when I'm in there. Do you know a good place to order internal engine parts? Thanks again for all your help. You have been very informative and straightforward and I really appreciate it. I was expecting a lot of "Take it to so and so, or this marine shop" type of comments. I can rebuild a car engine fairly easily so with a little research I doubt (hope) I won't have much difficulty with an outboard.

Obtaining parts for your old Johnson/Evinrude is no problem at all.

But if you are tooled towards automotive stuff you will need the following special tools if you choose to overhaul the powerhead yourself:

*OMC Lift ring/flywheel puller.

*Flywheel holding bar.

*1/2 drive 1 5/16" socket.

*3/8 drive 5/16" 12pt. IMPACT socket.

*Crankshaft seal remover.

*Ring compressor.

*Connecting rod cap alignment tool.

*And access to a good machine shop that is familiar with ported blocks. (I use HGM boring/sleeving in Lebanon, Mo.)

Your 140 has what is known as "High ring- Heat & beat pistons", and you do not wanna go back with those.

Go with Wiseco 3173's and a ring gap of .015-.017
