SOURCE: Leaf Blowers Features

* CFM (cubic feet per minute) is the measure of vacuuming power. Ratings fall in the 350 to 600 CFM range. * MPH (miles per hour) measures blowing. Leaf blowers perform at levels from 125 - 210 mph. * Decibels (dB) is the noise rating. * Reduction ratio on mulching blower/vacuums calculates how many units of leaves the mulcher can produce. A 10:1 ratio means that 10 bags of leaves can be reduced to 1 bag of mulch. * Speed settings allow better control when blowing or vacuuming. * Attachments, such as extension tubes for cleaning gutters, are available separately.

I have a McCulloch, that the hose rotted off the fuel strainer in the tank, I replace the hoses, it ran for awhile then stopped, removed the carb. an have cleaned, { 7 Times} it runs for awhile then stops, Usually I dump lighter fluid in the carb. if it starts Ign is OK if not its a fuel problem. You could check on the filter, I still have a problem with mine, its a pain when your on the roof an it stops. so check the fuel filter is the only thing I could suggest to you GOOD LUCK

SOURCE: what is the gas oil

Most Ryobi products made in the past 5 years use a 50:1 fuel mix. Check the fuel cap to see if it is listed there. The older Ryobi product used a 32: 1 fuel mix ratio and it was usually listed on the sticker that shows you how to work the choke. If in doubt, go with the 32:1 ratio. The only thing it will cause is premature fouling of the spark plug. Too little oil in the mix will cause premature engine wear.

50:1 is 2.6 ounces of 2 cycle mix to each gallon (U.S.) of gasoline.
32:1 is 4.0 ounces of 2 cycle mix per gallon.

I recommend to use a 2 cycle mix that is specifically designed for lawn equipment and contains fuel stabilizer. The ones with stabilizer will usually be .5 ounces larger.

Good luck!
