Re: can u damage a power head

oh my god you people can make me cringe haha..................FIRST OFF, i used to be a marine mechanic and i've been buildin motors all my life so just listen to me here. ANYTIME a motor has been sittin up the first thing you do before anything else is get oil into the cylinders, bearings, crank,ETC. then let it sit over night. sorry but your mechanic definatly should have known better. YES you can have one bad cylinder, i think i read that earlier someone said you couldnt have one bad and the rest good, but you definatly can have just one bad one. so all of you people saying that the motor should have been properly fogged or whatever else, sorry but fogged or not that mechanic should have oiled that sucker up and let it sit over night, we never EVER shot a motor off that had been sittin for awile without lettin her lube up overnight. ya its gonna smoke when ya wake her up and shes gonna spit and moan, but it all burns off and your good to go. now off to the guy that sold it to ya.................if only one cylinder is bad then he probably screwed you. if that motor was dry enough to scar cylinders on a compression test then it would have gotten more than one cylinder. so claim lemon law or whatever on ebay if i were you......sorry this happened to ya

Re: can u damage a power head

My question is what kind of a mechanic would take any engine part that moves and not be SURE it was lubricated first before he tried to use it. If only one cylinder is low I wouldnt blame the one testing it. Why does the seller know how it was tested anyway? Why bring a mechanic into it? Should have said,,"engine compression isnt correct and I want my money back" I agree with others and would bet the cylinder was low before you got it.

In this case he was testing compression, not starting the motor. And as for getting oil into the crankcase? A 2 stroke is an air-pump. Putting oil into the cylinders is not going to lube the crank. When the engine turns over, air (and everything else for that matter) is sucked out of the crankcase and pumped through to the exaust.

Even so...how exactly did the mechanic cause scoring in the cylinder? We're talking about a machined surface in the cylinders and cranking RPMs is not going to generate enough heat to do anything. UNLESS of course there was rust in there...and as mentioned in the first few posts if it has rusty internal parts then it's toast anyways.

Read the OP post. The mechanic was the one who tested the compression.

Why bring a mechanic into it? .

The mechanic was installing the powerhead for him.

Re: can u damage a power head

I guess I mean that the seller only knew how the engine was tested because he was told and that brings the mechanic into it. The so called mechanic should not have spun the engine over if he knew it had been sitting. The engine will have to been checked for indications it had recent damage due to lack of lubrication and not just low compression on the one cylinder due to wear that took place over time. The seller has a way out and I would look for me another marine tech .
