You seem to have more in depth experience on the diaphragm matters then I do Jay. Im going to assume you are correct.
 
Leaving even stabilized added gas sit in the carb for storage will still toughen up the diaphrams. I run my saws dry by repeatenly choking the carb till it no longer fires. When the very last of the gas residue evaporates when sitting in storage, all that's left on the diaphrams is mix oil residue which depending on quality should help keep everything protected and limber.
 
You guys are making me realize just how lucky I am to be able to get alkylate fuel.

No stiffening/hardening of seals or diafragms and the fuel never goes bad.

The price sucks, though.
 
Man I got all excited when I seen the title. :lol:

We used to do 40cc under Top Handle saw class racing in 8x8 2 cuts. :D

Sure wish this stihl chain in PS or even PS3 was around back then 08 and 09. :cry:

Ive learned something today.
 
Probabley just as a matter of preventative maintainance it might not be a bad idea to rebuild the carb .If it doesn't need it now no doubt it will will in time .
 
Willard, I'm curious, previous to storage, why do you choke the carb to run the engine dry? I just drain the gas from the tank and let it idle until it dies, listening to the death pains. They generally wont start after that? Are you saying that choking leaves more of what you see as a protective residue on the diaphragms?

It seems that diaphragms have to be pretty well stiffened up, before they will affect engine performance very much.
 
It isn't just the main diaphragm that goes funky .The check valves get stiff and don't seal good .The more modern kits have a mylar type which stands up to ethanol better .However in spite of that the big diaphragm goes stiff and you end up rekitting the things with maybe just a short period where it lasts longer than buna-n checks .

Evidently constant usage must prolong things because Tom doesn't have nearly the problem that I do with funky carbs simpley because his saw get used more I think .
 
Good info on the check valves, Al. I didn't know that. Maybe it is old gas in particular that has the more destructive effect on diaphragms and such? The rather stinky smell it gets seems to denote nothing much good going on with it. Fresh gas smell on the other hand is more sublime.....cough....

No ethanol gas here, and only one octane choice and I don't know what octane it is, two dealers Esso and Rubis (Shell)
I reckon it's the old gas...but at $8 a gallon one is loathe to chuck it out! Save it for parts washing maybe...

Love the poster Willard!
 
Wow, I though the Nips were high! No refineries on the island?

I hope it's the gas, Fiona, but my experience with bad gas in saws doesn't make for a racing engine. End the suspense, buy some new fuel!
 
Only time I have saws act up is when they sit. Minus broken chain brakes a Stihl dawg bolts backing out.

Refineries! Haha!
Our gas, diesel and kero arrives ready to go on a ship from Venezuela!
It was almost $10 a couple yrs ago when the three month supply was purchased when oil was $170 a barrel...

Yup, taxis are expensive...but clean and airconditioned, they have a dress code and a code of conduct for taxi drivers.
$30 for about 10 miles, airport to hamilton (the capital)

No rickshaws, no jitneys...oh classic TH derail!

My father inlaw is doing contract work in Saudi Arabia upgrading transformers for parts of their power grid. He says when he fuels up his company Mercedes car the price of gasoline is 12 cents a liter or 48 cents a gallon.
No ethanol and the lowest octane is 94.
 
Here you go, Fiona, a miniature refinery delivered right to your door. Think you could swing getting some crude and a place to brew? You can probably tweak the octane, and for God sakes read the instructions! :lol:

Ha, you laugh!
I could see that going here, get a spot out on the old navy base, bring in some crude...let 'er go...
SOmeone's already doing biodiesel somewhere, you get a whiff of french fries every now and then from the odd truck.

Hey Butch the taxi drivers are our first contact ambassadors for visitors, they have to project the right image. Bermuda is an up market destination and prides itself on cleanliness, hospitality and being a well regulated low tax jurisdiction 8)
We are streets different from the other 'Islands'.

Haha...its WORSE now Al! Narrow roads, tight corners, and US sized SUV's are here that don't like to be driven slower than 50k...I regularly get overtaken driving at 45k (that's a tad less than 30mph peeps)
No wonder there are scrapes and scratches on the rock sidings, and stone walls with holes in them everywhere.
