Every year I clean my carbs, and every year they look clean, but I clean them anyways. For whatever reason though, this year was different.

Every bowl I removed contained small yellow ballls, I'm assuming this is gas. Please correct me if i'm wrong.

The only two things I did different for storage this year, was fog the cylinders, and I ran 87-89 oct. instead of 93 all season.

Please give me your questions, comments, and concerns, if any.

Thanks, Spaz
 

In Canada, Premium fuel has little to no "Ethanol". I suspect the difference you are experiencing is from the poorer quality of fuel you were running and left in sled for storage. I normally have a blend of 100LL Av Gas and premium fuel[no "E"] in my tanks/carbs when the sled gets stored and the carbs are always clean and good to go for the next season. When I parked my SRX last spring it had "TrailSide" regular[at best] fuel in it and now this fall my bowls were dirty and pilot jets were plugged...maybe someday I'll learn!

I don't know about Illinois fuel but I suspect ethanol. I typically see white gel like balls in the bowls I've pulled the past few years. Seem this year has been a banner year for these little balls. I've had at least a dozen carbs apart this fall and all but two had them.

If I'm not mistaken regular 87 octane fuel is yellow so perhaps your balls are yellow because of the die put into the fuel.

Better yellow balls than blue.
 
Thats Ethanol causing varnish.... dont store your sled with any gas or at least high octane with sea foam. Drain carbs once fogged and gas treated.
 
i have had the same thing the last two years. i assumed it was from spraying a ton of fogging oil into them for summerization. i guess it could be the ethanol though.
 
So adding a decent amount of Stabil and running it through the carbs. won't stop this? I always run 2-3 times the recommended amount of Stabil to try and stop this from happening, obviously it didn't work this year.

Also, the only reason I store the sled with gas in it, is i've been told it makes next seasons start easier. Through research though, it sounds like SRX's are a beast no matter what. In the process of researching the viper carbs.

Yamaha does not (nor do I) recommend storing with fuel (treated or not).



The ethanol is an important part of the octane rating in most premium fuels and if/when it seperates not only do you run the risk of contaminates in the fuel (the jelly fish) but also a lowing of the octane rating.

No big deal for a 6.5:1 CR lawn mower but in an SRX?

IMO - fuel treatments (Startron, Stabil, Seafoam) are fine for low performance 4 stroke applications but for most 2 stroke applications I wouldn't use it... not even in my Husquvarna weedwacker. When you need the anti-knock compounds the most (first snowfall - WFO long pull across the lake woo-whoo) they might not be there, but Mr. Squeaky might be.

I'd rather pull the plugs and pour pre-mix for season opener than pull the plugs and find melted aluminum.

The gas now days sucks and it will varnish easily with ethanol there for high octance is best with zero ethanol. Stabil and ethanol dont mix well so seafoam is the better choice. With gas sitting to long it looses its ability to burn the longer it sits and once mixed with crappy ethanol and or water now you have problem.

I agree 100 %
 
Thanks for the input. Up til now i've always been told to leave the tank 1/2-full to full with gas, but never really liked doing it for the fact I have 8 month old gas in there and its junk.

Do you guys agree then; at the beginning of the season with the sled is completely empty of gas, fill it up with freash gas and pore premix down each cylinder to get it going?

Also drain the carbs ;)!

The most important part . . . IMO

I also like the entire system drained, but the carbs are key. The fuel in there will evaporate and leave anything that doesn't evaporate behind. The last place you want anything besides clean fuel/oil mix is in the carb bowl.

i just run shell premium zero ethanol no more white balls

Is that the new v-power/ nitrogenated fuel. I was going to get some but somewhere I read that you need to up the mains one size with that nitrogenated stuff.

AMSOIL Quickshot SE

I read about this recently.....anyone know anything about it?




AMSOIL Quick Shot wins SEMA award

AMSOIL Quick Shot wins SEMA award
AMSOIL Quickshot SE Awarded Best New Powersports Product by SEMA Judges
AMSOIL Quickshot SE Fuel Additive has been granted the Best New Powersports Product award for 2011 at the SEMA Show at the Las Vegas Convention Center. This year, over 2,000 new products were submitted for consideration of this distinctive honor in various categories. In determining the winners, judges looked for superiority of innovation, technical achievement, quality, consumer appeal and marketability.

AMSOIL Quickshot SE is a premium fuel additive formulated to clean and restore optimal performance in small engine and powersports equipment fuel systems. It acts as a fuel stabilizer between uses and short-term storage and helps prevent damaging corrosion. Its revolutionary formulation focuses on three major fuel-related issues common in small engine equipment: ethanol, water and dirty gasoline.

AMSOIL Quickshot SE is designed to keep water dispersed throughout the fuel tank, moving it out and decreasing the chance of ethanol separating from the gasoline. Moisture finding its way into gas tanks through condensation is dispersed in tiny molecules and safely moved out of the tank through the combustion chamber. The lack of additives in today’s gasoline can cause fuel system gumming and varnish, creating deposits on critical components. AMSOIL Quickshot SE cleans hard to remove deposits on pistons, spark plugs, injectors, carburetors and other combustion chamber parts to maintain peak operating power.

AMSOIL Quickshot SE is recommended for use in all two-and four-stroke gasoline powered engines including motorcycles, snowmobiles, personal watercraft, boats, ATV’s, edgers, tillers, mowers, snow blowers, chain saws, generators and farm and construction equipment.
