👍👍 I think the knowledgeable folks talk about blowdown too, but they have the wisdom of knowing how much intake/crankcase size will make it run well. Nice job!
There's no replacement for displacement!!! That's why that 064 can keep the ram's up but buddy that 7900 is no slouch I'd be proud of that!!! Awesome job
Really like how the 7900 runs. Only have one question did you take 40th off the base and run it with no gasket? Big fan off your channel like the way you approach things👍🏻.
Hell if a good job. I’m glad those guys have you some solid advice. I’ve never built a dolmar so I didn’t see any reason to chime in. It turned out great though
Before you ship that saw off, it would be nice to see if the HD filter is holding the saw back. Don't get me wrong, you did a fine job on the saw. The "sewing circle" claims the stock filter flows more air than the HD. Be interesting if you could rig up a more traditional filter and see if it actually made a difference.
heard that about the hd filter. I've tried both, and I'm not sure, I did have to tune it slightly on the hd filter. Dunno how it can be much worse it has a bigger surface area. The only thing is that maybe the elbow slows the flow down a bit as never tested back to back, I think they perform worse with stock exhaust/slr and not tuning the high jet from my limited testing. Definitely needs a muffler mod🤷🏻♂️
Dam straight it’s all about cutting the wood. Think of how much wood you have processed with a stock saw. Does any saw really suck if it cuts? I know how much you like the ms170, well I ran my buddys cutting way to big of wood until it overheated and didn’t want start after refueling. Guess what, it still runs today even after that abuse. And no I would not recommend that saw to anyone. I’m still waiting for you to get a new shirt in your store. When you do leave out the TH-cam logo. I’d recommend using your channel logo and place it on the pocket of shirt if you can get pocketed shirts. Everyone needs a pocket on there shirt.
Still a few out there but guessing the deals are long gone. I like mine a lot but it’s no 066. Not in stock form anyway. Now if I only knew someone that could turn it up a little. lol
@@dgoodman1484 a little hard to compare a 92cc saw to a 79cc saw. I don’t have either. My biggest is a Poulan 5200 (85cc). I love running it. Any chance you are in upstate NY? I’d work on it for you.
The big difference between the two (obviously besides the size difference) is the epa stuff like the choked muffler, limited coil and hard to clean up the carb. 80cc is plenty if a guy could just clean them up a little and get them to run like a 90’s saw. Heck even my little stock 034 supers will outrun my modded 620’s and the new 562. The 562 shows some pretty good potential but betting it won’t hold up like my old stihls have. Luckily I don’t run them 60 hrs a week like I once did so I’m sure it’ll be fine. Still wish that 7900 ran as clean as my little ea5000 does. It’s great for its size 👍🏼
Interesting vid there. Strange how you said the dolly is pulling higher rpm. I actually thought the stihl was spining faster in the cut from the sound before you put side by side...kinda sounds more tinny. thought the stihl was gonna win but the dolly surprised me. Very deceiving, they looked very even but tune on the dolly sounded like could be leaned a tad though hard to tell from the sound on here😂. Nice job though👍
@@walkerscountrylife Older I get the more I dislike the cold, @ 4 weeks and we'll be in our peak winter time, does not get real cold @ here though 0°F is our coldest temp usually. Have a good one James!
Since you say blowdown does not matter... i wonder how you gonna make power from fresh air fuel charge that is lost out of the muffler because your transfers are too high....?
That's a good one! Seriously. If you are losing charge out the exhaust, the way I see it is still directed at the transfers. It's simple and you already said it- the transfers are too high. Having too little blowdown is nonsensical. Think about it...did your exhaust not have enough time to escape? Nope. In fact, it had too much time and has taken some fresh charge with it. Blowdown is a description of how long the exhaust has to escape the cylinder, measured in degrees of crankcase rotation. Well, if that's all it is, then why does it change between different saws that have the exact same piston diameter? Different blowdown numbers give various different power characteristics. Why is that? Does one saw flow out the exhaust better than others? Certainly this is a possibility, but I feel certain it is because of the different transfer heights...NOT blowdown. The transfer height changes when fuel charge comes in, and for how long. This is what changes your power characteristics, NOT blowdown. The folly comes in people referencing the blowdown duration when talking about power characteristics when they should be talking about transfer heights and crankcase pressure. In your example, you didn't need more blowdown. The exhaust had plenty of time to get out, it actually had too much time for the exhaust to leave. What it needs is either shorter transfers...or advance the timing. It's a different way of looking at things. Blowdown does not effect power characteristics. It is simply the amount of time the exhaust has to leave before the transfers activate.
Ike Turner is just a bad bad boy! The Makita 7900 cut good but Ike Turner flew through it! Dang i don't know they were purdy equal by that you really cant tell unless you wack'em off!
For my money the two best saws Stihl ever made are the 200T, especially for those who climb, and the 064. Amazing saw those 64’s. Great content. Ty

I'd like to get a Dolkita but I've heard replacement parts are crazy expensive.

Wow both of those saws run great. I’d love to get my hands on a 7900. Good job.

Try doing a stihl 291 cylinder and piston on a 271.

What did you change on the 7900 dude? It runs well!
👍🆙JW, How's the weather over there?

Looks good
Amazing work in that 064 sir.
@justinweaver8107 definitely a good saw
Do u still have the blue c10 or the 6cyl engine out if it?
The C10 is long gone buddy. Cool old truck, but teenie tiny little cab. Not enough space for theses long legs. Dodges always have bigger cabs.

Love em both
That 064 acted like it’s got a broken clutch spring. Be careful with it!
Just idles fast when cold. Quits spinning the chain once it's warmed up
If it quits spinning after it warms up must be just a touch lean on low end
Great job on that 7900!👍🏻
👍🆙AP
You asked for it….. and we need it. PROPER WACK OFF!!
I don’t care which one is faster. They are both great reliable saws.👍🏻
They both are good saws man! But the Stihl is a little bit faster I think 😮😊
Nice job on the Makita. You really woke it up. That 064 runs like a scalded dog so anything close to the Stihl is a good runner.
Ike Turner is just a bad bad boy! The Makita 7900 cut good but Ike Turner flew through it! Dang i don't know they were purdy equal by that you really cant tell unless you wack'em off!
Next project turbo barrel 😅, sounds Better Makita
That's sweet 👍👍
Hey😊
Dolkita looks a touch faster
Makita faster
Yes sir... You built a runner there..... Pretty much on par for sure.... Need a wack off for sure!
