Would not hurt as it will act as a thread sealant too.

As get older you will find the need for extra equipment. With my back problems I use the 2T engine crane here a lot. Yes I know it is over kill but when it takes some moving around a longer period my back thanks me the next day. But I am considering one of those gantry crane as the folding legs of the current crane keep getting in the way. I just don't like the idea of leaving it out in the weather.

I would love a gantry. I just don't have the space for it when it's not in use. I've been imagining building my own that is fixed to the wall on one side and folds away when not in use. I may just break down and get a normal one. I have a chain hoist but my garage has trusses, unfortunately. I'm afraid I'll bring the ceiling down on top of me, especially with a snow load.

I had injured my arm 2 weeks ago helping a friend move something. My ego tells me I usually wouldn't have had a problem pulling this engine out. I thought I was healed but I just reinjured it. I'm old enough now to be injured but still young enough to think I won't be. It's a deadly combination. I still want that crane though.

Pain is a great motivator.

I got everything back together just now. I went 5lbs under on the dry torque spec. My thought process was that the loctite is slippery and the threads are obviously not pristine as some material was removed toward the end. If I'm off base on that, please let me know. There's still time to put another 5lbs on that bolt I'm sure. I was going to let it sit overnight before I tried any testing to let the loctite set up.

Thanks

Lefty, My machinist says he was taught that as long as you got good threads length twice to diameter of the screw you will achieve max holding strength and anything after that is just a plus.

I was worried about using some 5/8" length Heli coils here for the 5/16 screws until he told me that. Sure enough I can torque those 5/16-18 screws to 27 ft-lbs and they are holding. So in your case if you got 7/8" of good threads then you are golden.
to go to 55 ft-lbs. But yes you want to torque less when using liquid Loctite as it is considered a lube.

I have this craftsman machine with a starting issue. Presents as a dead battery but I've narrowed it down to a bad starter or compression release.
When I jump straight to the post and housing of the starter with a good battery, it behaves the same.
I adjusted the valves to spec and there is a slight bump on the intake. But I'm struggling to tell if it's adequate. My gut tells me that it's not.

My limited experience with busted compression releases has been complete failure with no bump. Do these failures ever present with an inadequate bump? Is there a spec for the rod travel on the bump?

Thank you

What you can do for a test is to drop the intake clearance down to near zero. But I have never seen a ACR worn down just broken.

BTW I think Briggs may be on to something as the last two camshafts I just ordered has a modified ACR pin. It is now hourglass shaped, reducing the contact with the lifter (tappet).
