“I learn by tearing something apart and seeing how it works.” From you first video… I am surprised to find this logic has gone away in the last 20 years or so. We live in a society where people buy cheap, throw away and buy another if broken. Like you I feel the need to understand how things tick. I’m a proficient chainsaw builder now, not great, but good. I can now apply what I’ve learned from chainsaws, to any 2 stroke motor. Way to stick with it, good couple of videos👍🏻
There has never been a better time to be a tinkerer; thanks to RUclips and the Greater Internet I feel like there's nothing you can't learn to do if you're willing to do a little research to get started and get your hands dirty to apply what you learned. Keep wrenching!
@@stihlhead3338 I feel that the big hammer is a very underrated tool. I've done the wheel bearings on my dump truck with just a big hammer. Someday I look forward to a shop with enough space for a press, but until that day, the right tool for the job is the tool that gets the job done :)
Good on you for sticking with it. Cause and effect. I dove in and bought the case splitter and bearing tools. I'm surprised at how much you can beat this stuff up with a hammer and it works. So another thing to look for is pressure and vacuum. I had a Echo 8000 that the crank seals went bad and ate the piston. Took me a long time to figure it out but I learned the importance of pressure and vacuum testing the short block before complete assembly. Something as simple as a cracked impulse line can really cost a lot of money. If your saw ever starts running lean for no apparent reason stop and check for a leak. I always use a gasket sealer for all my assemblies particularly in the case halfs and base gasket. Might be over the top but leaks destroy top ends. Looks like a pretty nice kit, I'm trying not to buy one but...I'm only human. Living life with only one 60cc saw could be a life regret that I may never forgive myself for. I sure can come up with stupid reasons for buying another saw I dont need.
Sounds like you really know your chops when it comes to chainsaw repair. How would you recommend going about pressure and vacuum testing? This saw runs now after the (repeated) rebuilds, but not well, and I can't figure out why. A vacuum leak might explain it, but I can't find one. Admittedly all I've done is visual inspection, though, as I don't have any way to measure the vacuum and even if I did, I don't know the spec.
@UncleMikesCustomThings your going to need something to accomplish the test. If you have any kind of vacuum pump like a brake bleeder, that would work. As for pressure if you were real careful maybe start your air compressor and only let it build to around 6-8 psi. Remove muffler and carburetor and block off both ports however you can. Use the impulse nipple to add about 5 psi and spray a soap solution on everything. Unfortunately that means access to both crank seals. Most leaks I have found have been with pressure although leaks can be with vacuum not pressure. If you can plumb in a low pressure gauge and use a hose pincher to keep a eye on the gauge, that would be another way to confirm on the cheap. My setup was about 120.00 which is expensive but it does both vacuum and pressure and has a gauge. Was more about convenience. Lots of good material on RUclips about the subject if you look for it. Check your compression as well. Maybe cleaning up the cylinder isn't good enough. Learning this stuff isn't cheap but I have found it rewarding. Most of the deals I find are nothing more than bad fuel/rotten hoses and a carb.kit. I'm looking for a Dolmar 501 cylinder at the moment. Got bit on this one because I didn't do research. Paid 165 for the saw and the cylinder is bad. No problem I'll just order a knock off.....doesn't exist OEM is 200.00. Saw isn't worth the cost. Good luck with the 460!
@@markw2266 Great wrote-up! Thanks for taking the time, that's super helpful. If I ever have the saw that torn down again I'll have to give it a try. How long should the case hold 5psi for?

This is the first time I have ever seen anybody put bearings and seals in with just a big hammer.😂

@UncleMikesCustomThings as long as you don't see any bubbles I would call it OK.
