two mods you can do to increase power without porting! this really works!

Iron horse. I’m 36 I have a degree in law and am also a qualified quantity surveyor. For 27 years I suffered from poorly controlled diabetes and as a result of diabetic complications my kidneys failed and I have also been reduced to 6 % sight. I had to give up my cushy well paying job but I didn’t mind as it brought me back to my first & only love which is the timber industry. I recently passed all my felling tickets. The point of my message being to never let your health stop you from what you love to do otherwise a big part of you will have already died. Best videos on you tube.

Hey - this is my first visit to your channel - I was signposted here by Buckin Billy Ray talking about your saws. I have enjoyed meeting you and hearing you talk about what you build, and what you do; thank you for sharing your know;edge. Like BRS you seem to have a gentle philosophy on,life, - which is all too short in supply nowadays, and welcome to hear. All strength to you! 💪

[@LukeScottNelson]

Buckin billy ray is the reason why I started watching this channel too

[@dannelson6301]

I just wanted to send along my sincere thanks for clearly presenting the two non-porting mods. Namely, the base gasket deletion and stock muffler modification, as discussed in this video. My old (very old) Stihl 031 never seemed to have the snus I thought it should have had. It bogged easily, even with a sharp chain and properly filed rakers. Now, after performing these two simple mods, the old girl wades through Red Fir like nobody’s business. PS: Your handle, “The Ironhorse” makes me smile. An old-timer that I used to hang with would always say this when making a point about something. He’d tell you a story, pause a bit, and then say “Iron Horse”. When I asked him about it he said, “You know ... iron horse ... no sh-t”. Anyway, thanks again for all you give us on your channel.

[@tomsommer54]

Great video. Beautiful weld job on the muffler. I’m Tom Sommer I live in Northwest Arkansas. I bought a Norwood sawmill about 8 months ago so I decided to log my 40 acre property. That’s what got me into chainsaw. I have a echo cs 590 24 inch bar. It was the best I could do after paying for the sawmill. It a Norwood HD36 V-2 with hydraulics. I needed the hydraulics. I’m 68. Thanks again for posting the videos. You have a great personality.

[@aaronpowell4885]

Definitely a sharp looking saw! I got the g660 pro a couple weeks ago and agree, after a basic tear down and reassemble to check it over, they've Definitely made some improvements over the "blue saws" from years past👍 squish on mine was .028 so I left the gasket for now. great to hear you're doing better!!

[@kingcosworth2643]

The best gasket compound for these motors and motorcycle motors is the Loctite 515. The compound is anaerobic, so it doesn't dry until it's bolted up, it can sit there forever on the surface and stay wet so there is no rush to bolt up. Also because anything that gets pushed out from between the surfaces will get washed away because it won't dry so it won't mess up the flow of your ports or block small passages, brilliant stuff.

[@theironhorse6600]

Great tip! I’ll try it!

[@johnropeleski6006]

I only use 515,used it for years.

[@Saltshaker762-KF4LBG]

Permatex aviation gasket maker is another awesome choice... Air cooled engines expand and contract a good bit... I'll give that other a try!

[@Derekfish]

​@theironhorse6600 love the video. Not knocking it. Just one little thing. ( not saying it's the only way) but when you remove the base gasket yes you raise compression etc. However you are technically lowering your ports in doing so. And will lose top end. You'll gain bottom end. I know this video was to point out not porting. BUT. If you took off 20 thou base gasket you should/could port 20 thou to the TOP side of the port to achieve the same power band curve. Then you'd have same power curve, more air, more compression

[@jamesbrooks5442]

Glad your feeling better. I know 100% of what you are going threw. I am a type 1 diabetic and have been for the past 15 years. It's hard & difficult at times but you can do it for sure. I sure am enjoying your thoughts of the 372 pro model. Thanks so much for sharing your knowledge with us.

[@rickwilson8754]

I just wanted to say that I enjoy your videos. Very informative. I found out 5 months ago that I have diabetes also. You are right about the fatigue and joint pain. Mine was 548 . It took me about 3 months to get it down to 85 to 120 . I feel great now. Good luck with yours .

[@patthesoundguy]

You are certainly looking like you are feeling better. I was wondering earlier today how you were doing.. I'm happy to see you are well. You answered a question that's been ratting around in my head lately, about if cutting the pipe flush in the exhaust can or having some pipe in like you explained was the right plan. I was going to experiment some with that and I still might when I test the different locations of the pipe. I had a chuckle to myself when I was checking the squish on the original cylinder on the little 34cc Poulan 2150 I'm playing with.The squish was so big the solder diddnt even dent lol. It still pulls awesome after porting and I actually ran it with a 36" bar and it worked great! I ported the exact same saw last year for my stepson but I used the aftermarket cylinder and the squish was right where it should be and I can definitely tell the difference. Proper squish and better compression on the little saw helps a ton.

[@rodneypackard8423]

Thank you for your videos. I have a 55 rancher that I put a highway cylinder and pop up piston on. It runs great. I also have a g372xp. Now I'm going to to modify it like the one in this video. You have taught me alot about saws and now I have the confidence to modify them myself.

the aging of the body is to me a diploma of life, you earned it, embrace it and be thankful for the story it tells. Nice saw. The orange 372 Holzfforma I bought (build date October 2022) did not have the well detailed cylinder...I looked...pretty rough inside and definitely no chamfering. I suspect the better prepared cylinder is a feature offered as an upgrade and part of that "pro" package of the carbon fiber version.

It’s also important to avoid seed oils like canola and soybean oil just as diligently as sugar and carbs. Partly rancid seed oils have an impact on insulin resistance regardless of what your out of the loop Doctor says. Best advice, just go full on no carb, carnivore and you’ll be a thin, lean machine within a year just by eating like humans always have. A pound or two of beef, bacon, butter, bone broth and eggs, eggs, eggs everyday.

Thanks for sharing Ironhorse. My son recently dropped in a 66cc chinese chainsaw that he picked up for $70. I was really surprised at how well it went.

[@CaliforniaCarpenter7]

I gotta say, the faux carbon fiber does look good! And I respect you for giving credit to the 50 class. They are the unsung heroes of the chainsaw World, but there is a reason that big box stores usually only sell chainsaws up to 59cc. You East Coast guys are too much sometimes, though. A firewood man in the High Sierras needs at least 95cc, although the majority of work can be handled by the 70 class. My little Gen 1 55 Rancher still gets whipped out all the time and it is a chainsaw that gained 25% in the cut after a muffler mod!

Perhaps try the carnivore diet? As a life long diabetic (who refused to take medication) the carnivore diet changed my life in the most indescribable ways. Weight, cognition, skin, blood-sugar, energy, teeth.... and so much more. What was equally fascinating, was analyzing what was happening in my body during each 'stage', as I am a trained nutritionist. If you would like me to point you in a the direction of some literature, give me a holla in this comment. Also, for KZbin content, check out Mikhaila Peterson's TedX talk for some real-world experience, and Dr. Berg and High Intensity Health for the science. Cood luck brother
