I just read up on the 10% ethanol gas and the differences between straight old fashoned gas and the newly available 10% ethanol blended gas. I don't understand how this could be a problem. If anything it seems that ethanol should run the same or maybe marginally better then gas? So what's the deal? I was running my mower it ran out of gas, the same gas I've had in my can for several months and was pre-ethanol, then I filled it up with new fresh from the station gas (10% ethanol ) and the motor just couldn't even out, it races then chokes and races and chokes and just won't get up to speed.
Coincidence? Or a bad omen for ethanol blended fuel and old motors? 5hp Briggs and Stratton at least 8 years old. Thanks!

My guess is that using E10 in an eight year old lawnmower has probably dislodged some debris in the fuel system and now it clogged up the carburator.Ethanol is also a solvent and older enginesthat arn't used to it may suffer similar problems.I woul drain the fuel tank, then fill it with regular gas.Clean or replace the spark plug.Pull off the air cleaner,and get some gumout spray.After you get it running slowly spray some gumout directly into the carb at high RPM AND TRY TO AVOID stalling the engine.This may help get things back to normal.Good luck.

First off make sure that you didn't suck any dirt into you carb. A very small grain of sand can make the carb go nuts.
As far as ethanol, Briggs and Strattons stand is the E10 is not recommended, but it can run on it. E85 is a no. Ethanol burns hotter and is an alcohol. Alcohol and the older plastics and rubbers don't get along very well. I have seen this a lot in chain saws and weed trimmers.

lawn mower engines, do not have that much compression like a car engine does.
The mower that old will run, but the needle valve adjustments will need to be adjusted for better preformance.

sound more like by running it empty something choked up the filter or more likely the float in the bowl is hanging up
