Why do small engines still use carburetors?

Why do small engines still use carburetors?
I'm sure it's down to economics. However, is a module and injector so far out of the question for an expensive snow blower?
With an injector system we can forget many of the blasted carb issues we have, especially with modern fuel problems.

Sure injectors still get clogged, but in a small and relatively simple, accessible system, we can just keep several injectors on hand, just like you do spark plugs, right?

Can someone enlighten me as to why we aren't seeing this, and do you believe we will see it in the near future?

Thanks,

Tom

ariens is offering EFI on their new blowers for an added $300. In the showroom they start easy..LOL. It should solve the carburetor, bad gas issue.....but I would rather they just take ethanol out of gas.

For sure, but even with E0, EFI solves a range of adjustment issues, even problems with carbs you can't adjust, etc.


Just think, no more mixture screw adjustments.


I'd shell out the $300!

Yep, just this year EFI (electronic fuel injection) appeared on snowblowers for the first time. Ariens is the first to offer it.
I'm sure the only reason it took this long was cost..it will probably become more common year by year.

EFI is coming in in a big way. It's taking time to build momentum but im sure in 10 years there will be more EFI options then carbureted.

John Deere has expensive garden tractors with EFI, Cub cadet has affordable lawn tractors with EFI. Stihl and husqy have EFI chainsaws. Honda has an EFI engine in there 7000watt inverter gen. Now ariens with snowblowers.

Slowly but surely.

Cost savings is the biggest factor.
If everyone wanted and was willing to buy an EFI unit, it would drop the overall production cost of the system and keep it lets say at $100-150 more than a carburetor unit, but even a lot of dealers do not want to order them afraid of having to deal with issues afterwards.
At some point, slowly but I think eventually most small engines may go the EFI way for fuel economy, but specially if the EPA gets involved and it gets mandatory........

When the average snowblower uses less than $5 worth of gas *per year*, I dont see how fuel economy could ever be a real concern..

Oh right..when the government is involved, it doesn't have to make sense!

I recall the first car I drove with EFI. My in-laws 1987 Mercury Grand Marquis 5.0. Started it up on a very cold winter day. No roaring fast idle, no surging, no stalling etc. What a revelation, after always having carbs on all my vehicles. My first car with EFI was an '88 Mazda 323. Same thing reliable cold starts and smooth running all the time. Over the years I have had 3 more vehicles with EFI and they have been mostly trouble free as far as reliable running. So I would like to try an EFI snow blower when it comes to the size I would buy (if ever)..single stage.
One thing I'd tell anyone, if you are somewhat mechanically inclined, and are willing to learn, one of the best things you could do is learn how to clean out small engine carbs. 90% of the time this is your problem, caused by evaporating gas in the carb or fuel bowl. I run mine every 3 months at least and that seems to keep fuel from evaporating and I have not had to take carbs apart all that often. As far as ethanol we have no choice here in southern NY due to the totalitarian EPA forcing something on us, that we never asked for. This is a point some might do well to consider. It is more than just EPA though, its all political and also pushed by the corn lobby. Funny thing is that people in those states have a choice, they don't have to buy E10.
