31cc MTD garden tiller. Runs on idle at setting 1. Killed quickly when setting moved to 2. Has sat empty for a month. Gas used to mix w oil was from a can that has been in the shed for 2 months. As the engine idles there is a sticky fuel drip down one side.

Your carburator is probably gummed up remove it and clean it

clean carburator

try fresh fuel fuel is only good for 30 days in small engines if not the carb needs a good cleaning

Look on top of the machine.If there is an oil fill then no you do not use mixed fuel if yes it needs engine oil,30 wt.If there is no engine oil fill then you use mixed oil and gas,at a 50:1 ratio.

I always suggest using a full synthetic 2 stroke oil for these machines. It provides superior lubrication qualities and burns cleaner than conventional oil. The fuel/oil mix ratio is 40:1. That is 3.2 ounces of oil mixed in 1 US gallon of gas. Half that to mix up a 1/2 gallon. You can find this info and more in your manual. The fuel info is located on page 10.

No,use a 50-1 ratio mix,the info will be on the bottle of mixing oil.

My Craftsman 31cc 2-Cycle Gas WeedWacker Model C216.51318 manual calls for a Fuel Mix (gas:oil) of 32:1

The pony tiller with a Briggs and Stratton engine only uses gas do NOT mix oil with the gas.

I was able to get information from someone's manual. I can't find mine. Would like a manual.
