Ariens efi problems

I've got the new efi and it hasn't run right yet, my dealer said to run premium gas with no alcohol, that's what I've been doing, changed the spark plug, it was badly fouled after 1/2 hour of backfiring and stalling, did I buy a mistake? The dealer hasn't worked on one yet. Im pretty handy, any suggestions? The blink indicator is ridiculous, impossible to count.
Thanks

all of today's machines are made to run on 10%ethanol gas. high test will help but is not really necessary . use a good NAME brand gas, shell,exxon/mobil,sunoco . whatever is near you, try to stay away from the off brand /no names. where i have found by testing to exceed the 10% level and many times be closer to 20 plus,that will harm the fuel system and engine,

what is the point having fuel injection if you can't run regular fuel? it sounds like you need to get the dealer to check it out and if need be contact head office if the dealer won't look at it. if you have to run premium ethanol free fuel minus well just saved yourself a ton of money and just got the carbed version.

Finn you were having trouble 10 months ago its under warranty why did you wait this long to have it fixed by the dealer
I would have had a backup machine dropped off free of charge until they fixed and returned the blower

Its there issues not having worked on one prolly bs anyway any top wrencher could get what he needs from ariens to fix it easy sheesh

Call ariens tell them this load of crap


So far its you that has dropped the ball

For carbureted small equipment engines (push lawnmowers, riding lawnmowers, snowblowers, generators, etc.) That isnt necessarily true, and might not be true at all. Most engines are still older designs, I have never heard that *any* carbureted small gas engines have been specifically designed to deal with 10% ethanol. Most, perhaps all, are not. Which is why non-ethanol gas is much better for these engines, and why ethanol is such a big deal/problem for these engines.

For EFI snowblower engines? I dont know..they might be designed with 10% ethanol in mind. I don't recall this specific question ever coming up in this forum before, this might be the first time.

Just put a $12 repop carb on a neighbor's 9-29 Craftsman. Runs like a Top. No further Comment.

with fuel injection there should be no issue with 10% ethanol. usually with carbs ethanol usually clogs things up or causes the needle or float to stick but with fuel injection if there was any bad fuel in the line the pump just forces it thru.

Here's the whole service manual for an Ariens snowblower with EFI.Downloaded this from Home Depot,believe it or not.It has a complete section on troubleshooting the EFI system.I would print that out,go down to your dealer and tell him to read it and fix your snowblower.It's not your problem,it's under warranty.


Right from the owners manual for an Ariens deluxe 30 EFI:

I went back and looked at your post from February when the trouble started with your blower.You said you added Seafoam to the gas because you suspected water in your fuel.


This is just my opinion,but seeing as though Seafoam has a lot of isopropyl alcohol in it,it might not be such a good product to use in your blower because of the fuel injection system being sensitive to fuels with a higher methanol content than E10.I wonder if the system is sophisticated enough to compensate for the added alcohol.I also wonder if it's possible that Seafoam could have a negative effect on the sensors used by the EFI.
