I’m a big fan of your channel. Thank You! I know I will never build a saw like you, porting or piping, but I do learn a bunch about power saws from you.
Big thanks for all these videos and instruction.. I've rebuilt and worked several 30-36cc rc engines, 2 chainsaws, and currently porting a ms390.. built some screamers just off your video series..
Thanks for the video and great information Tinnman. I love your nothing too hide and all saws are good mentality. You have a very special talent and I thank you for sharing it with us. God bless you.
Your porting series is awesome! I just finished it the other day. Now I keep eyeballing these clone saws online. I think I might save up some nickels and get one. Trying to get into a name brand bigger saw is a little bit out of my price range. The clones seem to be something good to pull wrenches on and not feel bad if it goes wrong. In the meantime I will keep playing with the smaller stuff. Thank you for sharing your knowledge with everyone. This is all entertaining and informative stuff.
I modified a Chinese 288 muffler by cutting out the stock small pipe with a hole saw and welding on a 3/4 pipe stub. Sounds and runs great on my ported 288
More good content. Quite entertaining! We got hit by that storm too here in lower North Dakota. Not much snow but it blew the rain cap off my chimney pipe.
I will never do any porting to my Husqvarna 435 (don't laugh) that I occasionally use to cut up firewood but I find what you do absolutely fascinating. I would love to have the knowledge and expertise that you have but I will just have to make do with watching your videos😀. Sending you greetings from the UK.
Hello tinman. I have a cylinder and piston off a g444. It's nothing like the other farmertec cylinders you showed . And the piston is not sloppy. If you want it let me know. I have 2.
Tinman absolutely love your channel . This is totally off topic but I was hoping someone could recommend good gasket making material to use for rebuilding an old homelite P350
@tinmanssaws Looking to build my first farmertec saw and was hoping you could point me in the right direction. Look for a 60-70ish cc saw but there are so many options i dont know where to begin. In your opiniom whats the best saw i can get get from farmertec and what parts can I use from their kit and what parts i should ditch and get oem or quality aftermarket. Thanks for your videos they are very informative.
I just watched your whole port series. I'm working on an ms 180 that got wet. It's my first engine rebuild. I was going to port this 180 but it looks nothing like the saw you ported. Should I just reassemble as stock or can I get some more power out of it? It's a learning project for me I don't care if it blows up I'm just trying to learn a little. Any knowledge you want to share with me would be much appreciated. Your porting videos were awesome if I was working on the same saw I dont think I would have any problems. Thank you so much for sharing a wealth of knowledge that. You've already saved me a ton of time and money.
the 180 is a clamshell style vs a cylinder on case (which is the way most larger / pro saws are designed) which is why it appears to be so much different than the ones shown. Crank bearings are retained by the cylinder in yours vs pressed into the case on the pro/ larger saws. There are still gains to be had, and it should respond to port work as almost all 2 strokes would. You should be able to do things like opening the transfers, cleaning up casting marks/ breaking edges on pistons, possibly widen intake and/or exhaust ports, muffler mods, etc with that saw. The nice thing is, even if you screw up a cylinder beyond what can be salvaged replacements aren't terribly expensive. I have ported a few clamshell style climbing saws with very good results. Just go slow, measure/ check fit a lot, make sure everything is clean when it goes back together, and have fun with it. Just be warned it is addictive, I have a ported weed eater as proof 🙂
@danielh4995 thanks so much. I'm not sure what the transfers look like on this saw I'll look around and see if I can find a pic with a label. I noticed on this saw the intake and exhaust ports were sharp with no chanfer and it's still stock from the factory. Is that typical?
@@ericskillern7069 Things like that are typical. Saws are mass produced items, the cylinders, pistons, etc are cast out of aluminum. Company then machines the cylinder bore, outside of the piston, ring groove, etc so it will function and it gets assembled and off it goes. It would likely take as much time to smooth all casting marks, break edges, match ports to gaskets, etc as it would to fully assemble a saw. The saw will function fine with the roughness and casting flaws so its not something they put time into. Oh and FYI I forgot to mention in my prior post you will need to tune the saw after doing any airflow improvements. Watch some videos about reading spark plugs and how to adjust the carb while running. Start on the richer side of fuel mix and slowly lean it out as you test it under load and observe the plug. A rich running saw might foul a plug or be slightly less powerful, but it wont typically hurt it otherwise. Too lean and it can easily burn it up.
@danielh4995 I knew they had to be tuned but I just watched the cutaway videos and now I know why. Still don't know where to grind for the transfers on this damn thing.
@@ericskillern7069 You can always start with widening intake/ exhaust ports, cleaning up casting marks on the piston, possibly a timing advance, and a muffler mod. You should be able to get a noticeable performance increase with those type of mods even with stock transfers. That would be a safe place to start, if you tweak the transfers in the wrong way you can run into usability issues, idle stability problems, etc so if you arent sure it would probably be best to leave them alone. One of the weed eaters I did I was going for the highest power I could with a stock can style exhaust. By the time I was done I ended up with a larger carb, intake, exhast, transfer, and piston work. Man will that thing cut grass fast, but it will no longer idle at a low enough speed to keep the clutch from engaging. Just a cautionary tale, is it an issue for a weed eater that only I use, no, would it be an issue for a chainsaw absolutely
Tinman I know racing isn’t the same as rebuilding a chainsaw. But I do have a couple of questions on the cylinders. The skirt diameter and length. We had some cylinders that were way smaller on the diameter and the length of the wall was quite shorter. What would happen if you took .005” off the diameter and shortened it about.075”? Like I said I’m just curious why something like that wouldn’t work on a saw?
Hey bud. Just wondering if you have had any wrist pin clips break on your meteor pistons? I built one and the ear fell off. Destroyed my cylinder. Rebuilt it recently but am concerned it might break again. Thoughts?
Will be interesting to see how a little clean up on the piston and just widening the transfer will translate to the final product. Of course while staying within the timing numbers. Just the attention to detail shows the passion of a master. Wonderful to be able to observe your skills. TC Mahalo Tinman 🤙🤙🤙
