Seafoam works miracles in these small OPE 2 strokes. I use it every year. Make sure you have fresh gas and a new plug too...

The past 2-3 years I have added MMO to my small engine gas and the gum/varnish problems have gone away. My POS string trimmer runs on Super-Tech oil (40:1) and I use 1 Tablespoon each of MMO and 2-stroke oil in 1-1/2 gallons of pump gas (10% ethanol). Startron also helps with water dropout, 2 teaspoons added to the fuel mix above. This has saved me a lot of problems as compared to just plain gas and its not expensive to add to fuel.. I know you guys hate MMO but it works for me and its cheap!

if u cant get it to run check the fuel line inside the tank is not cracked or leaking. I have seen the pickup line dissolve from the ethenol. replaced the line and all is good.

Enzyme Fuel Additive:

I ran a test about two years ago on an enzyme fuel additive and mixed it with various other fuel additives to see what effects it might have.

The result: don't mix it with anything else and here is why: The proteins in enzymes are usually globular. The intra- and intermolecular bonds hold proteins in their secondary and tertiary structures.

My results showed globular clusters of "something" that formed and settled and no solvent I had would break up these globular clusters.

I don't know what they are using for this "enzymatic" additive but I really have my doubts as to its efficacy.

I use the good Stihl branded 2 stroke oil and our stuff (few trimmers and saws) always starts good even with months old gas in them. So I'm guessing there is something in the oil to help. Someone mentioned "running them dry" at the end of the season...uh...that fuel is the only lubricant that engine has....so having it spinning with less than or no fuel in it is pretty dumb. Just drain the fuel out if you really think it's an issue over the winter. The most important thing....keep the fuel CLEAN. It doesn't take much debris to clog up a tiny carb.

I use ethanol free gas and Klotz BC-172, a splash of Chemtool will help for sure.

I used an enzyme additive some years ago, holy smokes it left white snot in the carbs, filters, jets, you name it, that were super difficult to get out, what a mess.

If you use your trimmer (and chainsaw) like an average homeowner (less than a gallon of gas per year) I HIGHLY recommend that you use premix fuel cans from Home Depot/Lowes/wal-Mart.

This stuff is fantastic.

No need to buy the $6 or $8 name brand (Stihl, Echo) cans. The $4.47 cans at Walmart are likely made by the same company and just as good, with just as good synthetic JASO FD oil.

The canned gas/premix made by VP at Walmart $5 a quart has a shelf life of 5 years, and in the fuel tank of your machine it's good for 3 years...I believe it is 90 octane. Works terrific.

Can't do it. I can't pay $20 a gallon for gas that I can get the same performance with my concoction mixtures.

K100G is my favorite OPE additive and it works great for 2 stroke applications also. I add 1/2 oz per gallon of gas and then add the appropriate amount of 2 stroke oil.

Never had a problem with HD's premix 50:1 fuel in a Stihl blower and Echo chainsaw. A ounce of Techron into pump gas for 4-stroke gear doesn't hurt. Can't get E0 in Cali without paying outrageous prices.
