It’s hard to say without seeing or knowing what level of wear your talking about. I would say if it’s a concern to you that they are badly worn and you have the coin to replace everything then may as well.
Otherwise it’s a trial and error project.
Personally I would start with another compression test. Keep pulling until the needle stops rising. If you did it that way maybe try another gauge. If it turned out to be ok. Repair the primer and start moving forward from there.
Tell tail should flow even if the t stat is closed. I know it’s a separate passage but I honestly could tell you exactly where that passage is. Have you tried the mono line or weed wacker line thru the tell tale trick yet?
I can’t remember if you said yes or not.
Yes like you have noticed you pull it out and it springs back in. Every time you pull it it squirts a bit if fuel. I pull mine twice and its enough. If it’s cold out I’ll go for 3 pulls.
If I’m not mistaken there is a detent on the primer valve and having the primer valve pulled out just a bit would let a bit of extra fuel in. Kinda of like having a choke plate partially closed on a very cold start sorta of day. If the extra fuel helps I would still be looking for blockage...
Sorry but I have to ask.
Are you squeezing the ball to prime the fuel line and does it go hard? If so I would be looking at the primer itself to verify it’s working.
Yea sorry about that. It was meant to say timing light. You did the right thing.
When you asked about the running light I was so confused then realized I was the one that cause the confusion.
Post #47 is where your at now.
I would say before you go any further try and find a machine shop that is willing to do this work for you. It’s getting harder and harder to find anyone interested anymore.

Yes you will need to completely remove the power head. It can be done by hand if your young and strong. If you have a tree close by you could use a come along or block and Tackel. There are many ways to do this. Your question about removing just the cylinder is a bit concerning. I feel like you...
If tank doesn’t vent it will not provide fuel.
It will become vacuum locked.
If you cant get the vent open then open the cap a bit and see what happens.
Yea if bogging is more a problem than the surging then it may not be the hub.
But it’s a free test and you can check it off your trouble shooting list when your done.
Best of luck
