slomo: I'm not quite sure what you are saying in your post, but I did ensure that the crank and cam punch marks aligned. If is curious to me that, despite multiple posts regarding the hole punched in the valve push rod pocket, and many kind attempts to help with my problem engine, no one has...

cpuvis: There is no oil in the muffler, except what is coming from the cylinder. slomo: Yes, this is the 180 psi compression engine, a Kawasaki FR691V. The ACR does not adjust the timing rather, it temporarily opens one of the valves on each cylinder to reduce the compression...not sure whether...

I previously asked about the possibility of the valve push rod pocket with a hole in the bottom (next to the tappet),that had the bottom knocked out by the loose push rod, allowing enough oil to get into the valve cover to enable it to leak through the valve shaft seals and into the cylinder...

When I removed the crank case cover, the cam + governor assembply just lifted out of the case. The fingered governor plate stayed attached to the governor control lever, which is part of the cover. I completed reassembly of the motor today, fired it up, and the behavior has not changed...still...

I see that the cup and six ball bearings, that I previously asked about, are the governor mechanism. I note that neither the crank case cover and/or cam installation proceedures mention any special process to engage the two "fingers" on the governor shaft into the cam shaft. Is it correct...

Anybody know what the cam lobes measure out of the box? The service manual, as usual, only gives the minimum value.

The Crank Case Cover has no Gasket and relies on a soft sealant. What sealant is recommended?

I measured the Cam Lobes, and they measured: 1.150", 1.150", 1.154", 1.150". The Service Manual shows a limit of 1.156". This is slightly below the service limit, is this close enough?

I wish I was comforted by the high compression but I know from experience nothing comes for free. The service manual clearly states a compression ratio of 8.2:1...and that doesn't add up to 180 psi. I checked the crankcase breather (valve?) and it is completely open both sucking and blowing on...

Lawn Addict: Righto, I had a brain-fart regarding the flywheel key. Upon disassembly I had already noticed that the flywheel key was in the key-way. Also, you correctly quote the line from the service manual regarding compression, however it specifies the minimum compression. My previous...

Slomo: Thanks for you last post. At least we can have some fun. Per your last post, I've been through the rings, and they appear fine. I might just let the 10 acres of grass grow...how bad could that be? I do sincerely appreciate your effort.

I have not checked the flywheel key for proper alignment, nor do I know how to do that. I'm not sure how a flywheel key could have become unaligned. Tonight I checked the HF compression gauge by pressurizing it with my compressor, and it agreed to the psi with the gauge on the compressor. YES...

Slomo: I know the valve push rod doesn't push directly on the valve, however it is the push rod associated with the valve. I assume you're messing with me. Head gaskets = brand new Heads torqued to spec (oh god, its a HF torque wrench) Checking the breather hose/port tonight, will advise...

Slomo: The only timing check that I am aware of on this engine is ensuring the alignment of the punch mark on the cam gear and the crankshaft gear. I did check that and they are aligned. All gear teeth look like new. I don't see how the ACR would affect the compression test anyway, since I...

Engine was not filthy, just a little dirty. The fins all looked brand new and have never been clogged. It has been established that the valve guide softened and relocated, so at some lever it overheated. I think we are done with the valve issues. Per the previous posts: after replacement of...
