140 hp Johnson

Ok will do

[steplift20]

ok I dont know 1/3 as much as these guys on this site but first thing i would check is the water sepperator filter if you have one, take it off and dump the fuel in a glass jar to see if theres water in it and dont reuse the filter put on a new one if you have a water sepperator thats the first thing i would check, could also be a stator but i dont know how to check it . the way i checked mine is i took it to my mechanic and he checked it and replaced it 300 dollars later

ok everyone removed fuel seporator and everything looked good. just to be on the safe side got a new small tank of mix gas removed bowl drains on all four carburators. i pumped untill fresh gas came out, put it all back together and attemped to start. NOTHING. now this is where it gets scary got compression tester and as follows:
#1 @ 30 psi
#2 @ 29 psi
#3 @ 0 psi
#4 @ 30 psi

AM I REALLY SCREWED HERE?

I say yes...Sorry to see that. The numbers should be around 90-115 ( could be as high as 140) or so range and no more than a 10 psi variance

Dam, Sorry to see that Shurlock.

At least you know where you stand with it though. Sometimes I'd rather it be completley dead though rather just hanging on, causing you to spend more money on an old engine.

hard to believe it ran at all with those #'s. when it died, did it bog down or was it like your key was turned off. when you attempted to restart did it spin freely or was it binding and sounded like the battery was weak.
i'd pull the heads and look in the cylinders anyway, easy to do and nothing to lose.

Did you do the compression test with a fully charged battery and at full throttle?
And um yes.... Time to find a new engine

shurlock left here about 12:30 with it on its way to her new home after he heard it run. Hated to see it go as it has been such a good engine for me once I learned how to work on loopers(and the things NOT to do to them), but hopefully she lives on for many more years instead of sitting in my power corner. Hopefully this summer I can get bradfords old engine(the one next to it in the video) torn down, bore the bad hole in it, and get it back together.
