seeking opinions on 140 OMC problem

[lorax]

last fall I installed a new lower bearing in my '79 V4. I put everything back together by the book ie new retainer bolts, seal, o-rings, etc.<br /><br />I tried to start the motor over the weekend. Used fresh fuel. The motor sputtered to life once, briefly, and after that I couldn't get it to do much more than cough a little and backfire out the exhaust.<br />I pulled the plugs and they were soaked with fuel. I aired things out, cleaned the plugs and tried again. Still no luck. When I tilted the motor up for the trip back into the garage fuel rolled out of the air silencer.<br /><br />Is this problem related to something I did wrong installing the new bearing? I've removed the carbs and have started to look them over but I'm wondering if I should pull the powerhead. The motor ran great just prior to the bearing replace.<br /><br />Any thoughts?

I think you are headed in the right direction by cleaning the carbs. <br /><br />Good luck!

On some of the engines the gearcase propshaft bearing carrier can be install upside down, when this is done it blocks the exhaust thru the gearcase.<br /><br />I think i misread the post.

Sometimes you follow a thread on a problem somebody is having but never hear the outcome.<br /><br />For the benefit of those who may have followed this one, the problem ended up being a sheared flywheel key. The flywheel had rotated about 90 degrees and needless to say, wouldn't run.<br /><br />Many thanks to dhadley, clanton and also OB(different problem) for your input.
