I repair lawnmowers and most lawncare equipment and stuff as a side hobby/business.
Usually i can get them going good but this one has me stumped.
Its a 10-12 year old 21" craftsman 6hp pushmower self propelled that the owner has always ran it on non ethanol gasoline. Hes always had another guy make sure its tip top shape each spring (change oil when it starts to look black, plenty of new plugs, blades sharpened etc)
Well the owner recently put E10 in it and after a mow or two of his smallish suburbia yard it would get very hard to start. Prime it 3 times pull the cord will fire right up run smooth for a second then start sputtering and die. Do that routine about 4-5 times it will then start revving up and down then after it warms up a bit after 3-5 minutes it will smooth right out full speed no smoke plenty of power and will be fine till it runs outa gas or he stops it.
My first thoughts was the ethanol released some varnish from the gas and clogged some crap up.
Ive used 2 full cans of spray carb cleaner on the carb, float, needle, bowl, and just about everything else. I couldn't figure it out.
The owner all last season ran regular non ethanol gas in it and it slowly got better to this spring it did its start stall thing once then smoothed right out so regular gas is slowly fixing it...
Ive never seen or heard anything like this before.
Oh before he put e10 in it it started first pull and ran great.
also i forgot to add is once it starts stumbling and stalling if you press the primer button it will perk right up so its clearly fuel related.
