Why is this the 'correct' way to start a saw?

It's so that when you hit TDC on a high compression saw, it jerks upward, crushing your nads...
That Saw Troll has a wicked sense of humor... :msp_wink:

The reason I drop start saws left handed is if the saw kicks back it swings the bar away from you. I used to start them right handed till I had a 930 J-red slam the bar into my left knee when it kicked back. Good thing it didn't start & turn the chain. Now the proper way to start a saw is on the ground. But I never claimed to do things the proper way.:wink2:

Nor do I... But I've heard that about them J-Reds... Evil they are...

Right or wrong, I've always drop started saws with my right hand but the chain brake is always engaged so the chain isn't turning until I release it. I can count on 1 hand the number of times I've started one differently, unless it's been in the cut and I start it while still in the cut.

Your statement makes perfect sense for sure!

Jerret, the saw is on it's way to you I ended up running another tank of stihl dino through it today. It keeps getting stronger:msp_biggrin: Hope you enjoy it.
BTW, do you have any earmuffs???:msp_wink:

I have one more pic of the saw all cleaned up & ready to go that I'll post later. If you have any probs or ?'s please call the # in my sig & leave a mssg.

Stronger is good! Thanks for the quick turnaround time on this! I was expecting to be without it for a month or more. Hopefully I'll be able to get it in the wood Wednesday afternoon or Thursday morning and get some reports as to how it's doing. How did you send it back?

We all wear ear plugs anyway, as the M-Tronic is louder than hell as it is. With that light of a saw and that kind of power, I've already got Stihl pants on the way for everyone that's going to be running saws for me. Just not worth the risk anymore.

I wish my new M-Tronic would get here faster...

I think the boys will be arguing over who gets to run it...

I sent it back in one piece as I found it.

I sent it via US Mail priority.

One piece and a few ounces lighter! :msp_sneaky:

I doubt that...because from the videos, they will get "demoted" to the stock M-Tronic's and I'll be running the Stumpbroke!

Just the most practical way, if you don't want the bar to possibly hit you! :msp_biggrin:

:hell_boy:

you just can't handle the compression on a real saw.:taped::taped:

 

[Stumpys Customs]

Here it is ready to be shipped out. The last comp reading I took was after the second tank of fuel. I got 190psi. Not bad for not haveing a popup piston.

Have fun with it Jarrett

 

[John_DeereGreen]

Don't worry, I will have a blast with it! You wouldn't happen to have a tracking number would you?

Saw is back in my hands...after a little retune in the morning, it will be happily cutting wood again.

Initial impressions, as I told Stumpy on the phone, I feel like it is right up there with my M-Tronic in the cut. It's a very good running saw, I couldn't be happier with it so far. Stumpy does great work and is great to talk to on the phone as well.

I'm going to run both saws with the same bar and chain tomorrow if the rain holds off. I'm interested to see fuel mileage comparisons between the two saws as well. As expected before the mods, the 441 was about 15% harder on fuel than the 361. I'm not concerned about fuel consumption per time; I'm concerned about fuel mileage per wood cut.

I'll post a follow up after it burns some fuel the next day we can cut.

Thanks Stumpy!!!!!!!

Your welcome. Take care of it.
It would be nice to get a video comparison of the 441 & the 361 now. With the same size bars.

Will do! She runs to well to hurt!

That can be arranged...if I have time on Friday I'll do this and post them in here.

Well, I have a very happy report to make!

Yesterday was the first day that I have been able to get the weather and our firewood delivery schedule to cooperate and let me run saws since this one came home. I've had a few minutes here and there to play and get it tuned in, but I hadn't put much gas through it. Maybe a couple tanks off and on in the week it's been back.

Yesterday we cut about 15 cords, and execpt for about 20 cuts, this saw made them all. I tried everything I could to make my M-Tronic come out on top, including running the 361 with a 7 pin and 441 with an 8 pin. I went from 16 to 18 to 20 to 25 inch bars, all running RMC chain, and every single cut the 361 was at least 2 seconds ahead. I thought the throttle response on my M-Tronic saw was incredible, and it's now a slouch compared to this saw. The weight savings dropping to this saw allows you to cut more wood in the same amount of time, and it burns less fuel doing it. I've estimated the increased production has already paid for the cost of porting for this saw, and if it didn't pay for it's self yesterday it will for sure pay for it's self the next day of cutting.

Thanks Stumpy, you do great work...there will be more saws coming from me headed to the coop! Stumpy already knows this, but if anyone else knows of a 361 that needs work of some type, give me a shout. I'd like another one to have built so as to keep hours off the M-Tronic saw until it gets ported...

Wow!!! I was hoping that might be the case. Nice work and nice report.
