So I recently sold my non running 149 hydro barn find after found out it had a broken connecting rod and it wasn't going to be anytime soon that I would have time for an engine rebuild.
I have since found and purchased a 682 for an outstanding can't pass it up price!
Yes I know I don't think it is technically a IHCC its a CCC because of the MTD purchase in 81, (black rear end) But I think it was still built with the IHCC design.
I was told it ran good and worked good until parked because the PTO belt broke and the guy couldn'f figure out how to put an new one on it.
After a good carb cleanout (of a brand new carb that he had paid to have put on it
), it runs beautifully (besides being a gas hog, OMG!!!). It idles and runs so smooth and quiet its amazing.
It has the upgraded series 2 17hp kohler in it, was installed in 2000 at 850 hrs and the machine currently has 1291 hrs on it.
Here is the deal, when I bought it, I noticed that the left side engine head cover (shroud) was missing... I asked him about it and he said it was off when he got it because every now and then the starter bendix would stick and not engage.
So it was left off for quick access...
The problem, as most of us know, is that the air from the flywheel is going to escape and make it run hotter....
So I fabricated up a piece of sheetmetal and put a cover on it. The engine runs sooooo good and quiet when first starting it up but after about 5-10 mins of running and warming up, a slightly noticable tap / knock can be heard on that same side of the engine.
The oil doesn't look bad at all, although I do not truly know the weight that is in it but the guy said he ran 30W. It is also just slightly overfull, I mean ever so slightly....
The engine doesn't smoke AT ALL!!! None!!! Not even when I first started it and he said it hadn't been started / used in 2 years! NO SMOKE!!
Obviously it is a heat related noise but I'm just wondering what it could be and if it is somthing that needs attention now...
