Admittedly, I’ve “owned” the thing for about a week now, today was my first opportunity to dip it in the lake and see if it a) floated, b) ran. It did both, but the latter it did very poorly. It was sold to me under the auspices that the stator needed to be replaced. It didn’t take me long to negate that as the case, or at least that’s not the big problem. Starts and idles on 1 cylinder, second comes in with a bit of RPMs. Crank seal all the way baby.
I bought a leakdown tester and rigged up some plugs for the intake and exhaust. I learned today that not all 2 cylinder 2 strokes have a center seal(s). How that actually works, I don’t know – but I sealed off 1 side expecting I’d be able (prefer) to do the leakdown 1 cylinder at a time and was greeted with air coming out the other cylinders intake ports. WTF? It can’t be a center seal problem because only 1 cylinder is messed up. I came to the computer and googled and saw no existence whatsoever of a center seal on this thing. Like I said – how that works I don’t know. Poorly I’d guess, but whatever. I’m not about to go re-engineering Kawasaki’s Crankshaft and Crankcase that they sold 1 bajillion of.
I took the engine out, plugged both exhaust and intake ports up as well as I could; not as good as I did with just the 1 cylinder, but I was defeated at this point. Realistically it didn’t matter anyway, I was seeking to prove to myself something I was already 99% confident of. Sealed up pretty well, back on the air, the following YouTube video clearly shows it likes blowing bubbles just like a 4 year old by with a bottle of that soapy crap and the ring:
Other mentionables, with the engine out the grime in the hull cleans away pretty easy. I think with about an hour of Comet, water and a bit of elbow grease it will look almost presentable inside.
Compression is 120 on the PTO side and 130 on the Mag side. Not sure if that’s good bad or other, but it’s going to be what it is for now. So far I’ve found the thing super easy to work on and I’d like to keep it that way as much as I can. I’m going to split off the bottom to replace the seal and hope to go no deeper than that before shoveling it all back together.
Lastly, there is one picture where you’ll go WTF am I looking at. It’s a snapshot looking into the spark plug adapter for my leakdown tester, and what you see is uncleaned metal shavings. Way to go cheap tool company, couldn’t think of a better thing to drop down into my cylinder!!!
That’s it for day 1.
