Concerned

[steury]

I am finishing the work on my Evinrude 175 hp 1978. Model # 175849C<br /><br />Any way I rebuilt lower unit, control box, and pulled the head for a complete decarbonization with new gaskets.<br /><br />Now all put back together and started on garden hose. Engine sounds rough, Knocking it seems. Is this common when restarted after having heads off? Or did I cause more damage then I wanted to with the decarbonization. I want to go out and run it a bit to see if lubrication might help with the knock, but am concerned, don't want to be stranded out in the middle if this thing blows. I don't have auxillary motor. Any thoughts will be appreciated. and thanks for all the help.<br /><br />Steury Carl

Re: Concerned

I hate to say this, but pull the heads again,just to be sure there isn't something in the jug. That can't be good.You didn't remove the flywheel,did ya?<br />If so, make sure the key is all the way in the keyway,and the flywheel is tight.

Re: Concerned

Thanks for the reply 12footer. <br /><br />No, didn't remove fly wheel. Will remove heads again tomorrow, it appears I won't be out on the lake this weekend anyway. So anything specific to look for. Last time was pretty clean.<br /><br />Thanks again<br />Carl
