Pop ups and windows. Your thoughts.

My thinking is if it will mix with alcohol it will mix with and help displace any water and or other crap that's in the fuel.

I'm using HR1 right now and like it very well.

Me too! I got about 6 tanks through the 66, pulled the plug yesterday and the piston is still SHINY CLEAN even at 32:1!!! I really like it. Ill post a picture in Mdavlees original thread when I tear it back down for port work.....which may be today .

You tried that K2 yet?

 

[mdavlee]

That is good news durand. I was hoping it would burn clean. I'll probably mix 3oz per gallon of it just so it's an even number. Mixing with alcohol is important for a lot of people that have no access to ethanol free pump gas.

No I'm still using Belray........

e85 will take a good bit of squeeze.

holy popup :d

 

[Hedgerow]

Mine too. :msp_sneaky:

Hey Durand, is that your 372?

 

[komatsuvarna]

Hey Durand, is that your 372?

yep

 

[parrisw]

yep

What did ya do to get that much compression?

 

[tlandrum]

my guess is welded pop up

 

[parrisw]

my guess is welded pop up

I wonder, I've never got that much comp out of a 372 with standard machining, .030 popup.

 

[komatsuvarna]

my guess is welded pop up

Yep correct. Thats with a single ring too. I may tone it down just a hair more...... Its was ~220, and I shaved a little off it.

Do tell? How big? any pics.

 

[Hedgerow]

yep

I wondered about that... That saw is just nasty... It may be be pushing the envelope... How many hours you got on it as of this week...??? And of course, if you get tired of it you know where it can come live...
Just sayin...

 

[Hedgerow]

Something tells me it was alot more than .030... More like .090...

 

[komatsuvarna]

LOL, It started out about .100 to begin with. I ran one tank through it and checked compression and it was ~220. I pulled it back down and cut about .030 off it and it was at 190. Ive ran a lot of fuel through it since then so it should be broke in. I pulled 200 this morning. I had to buy a new gauge, and that was my test saw.

My exhaust is low enough I can throw a flat top back in it and have ~140/150 psi. The welded popup was an expierment.

I dunno how many hours, but I've put quite a few gallons through it though. Its fairly strong, But it still won't run with Tlandrum's XPW.







Im gonna have to figure out someway to pull a sneak attack on him.:hmm3grin2orange:

I keep hearing about his XPW, any reason why it runs so good?

 

[Hedgerow]

Cool, thanks!

It's a fine 372... By anyone's standards...

At the risk of turning this thread into an oil thread I'll throw this out there. If a crappy ethanol laced fuel is being used the use of a good oil is even more important. In the oils I use the ability to mix with alcohol is of the utmost importance.

And yeah, 200psi on crappy fuel is way too much. IMHO

All depends on how much ethanol we are talking about. Some oils like R50 mix fine up to about 20% ethanol, and even then is rare and only a separation issue during storage. Personally I haven't seen any mixing issues of any kind. Keep the fuel fresh, run good mix and enough of it and you'll be fine. Now if they start adding more ethanol things may change, but even then it's an easy fix for the oil producers.

HaHaHa!!!!


Try this.............if it works!

Was there build threads for these saws? If so I can't find them, please help w/ link.

 

[rms61moparman]

Try "Wildthing races at GTGs".
I don't know if there are individual build threads on each one or not.
