re: Problems with the premix fuel for small 2 stroke engines?

Almost all newer, high quality equipment comes with rubber and plastic that can tolerate ethanol. If someone needs to let a piece of equipment sit up for a while, they should just change the hoses to ones that are okay for ethanol, and empty the bowl out before putting it up.

The stuff that clogs jets usually comes from the hoses, the gasket around the bowl drain, or the bowl o-ring.


Eta: I recently picked up a new fuel line kit to go from the tank to engine at West Marine. It came with this grey hose that had some liner in it. First thing I did was switch it out to automotive fuel line

I was going to ask about that Mechanic in a Bottle...
My brother swears by it, I haven't had any luck.

I mix my own non-ethanol, but 87 octane. Few problems encountered.

I talk a lot to the project manager over the largest hand held outdoor power equipment mfg company in the world.
Yes, battery powered is growing and he is over that business unit also. Yes, they made huge investments in this sector just like robotic powered mowers. These are growth markets.

No, they are not stopping or slowing down on gas powered research.
The cost of battery powered products versus the technology to maximize the batteries power is what is keeping the technology from growing sales wise.

They also make commercial battery powered products, commercial docking stations to charge batteries,and battery powered zero turns. They do have people that purchase these products. Gas powered products are still way in the lead again as cost versus what the customer is willing to pay is not there yet. Batteries and cost are holding this back.

Run some Klotz Super Techniplate Castor Blend. It's made for racing two stroke engines. You won't burn up a Weedeater with it, has a good smell when it burns too. If you want something cheaper, Autozone has an air cooled 2 cycle by the quart. Don't run TCW3 marine oil in an air cooled engine. Doesn't have as much film strength. You want JASO FB, FC,or FD. The Autozone stuff is FB last time I checked.

Go to any local motorcycle shop and get a bottle of maxima K2 premix, or whatever decent synthetic they have. Now go to a small airport and get a couple gallons for 100LL Avgas. It mixes very well with synthetic oils and will have a much longer shelf life. Very minimal outgassing unlike pump gas, no ethanol, no odor, burns clean, absorbs less moisture out of the air. You can thank me later.

If you really want to have some fun, go get some VP C12. I ran my weedeater on C12 one summer from my race bikes because I was too lazy to go get another can and mix gas just for it. That thing ripped, you could hear the difference. It died at the end of the summer though. Not sure what happened, but felt like it lost compression. I should have taken it apart to see what went wrong.
