Ease of servicing is what is best about the conventional holley 2 and 4 barrels. Most of the passages are located in the metering blocks. Unfortunately they perform best at wot. Otherwise gas "mileage" is fairly poor.


Unfortunately, there's a lot of people on the lakes I boat, that think that's the only way to run. WOT!

Well, on something like that, I actually use a dedicated carburetor cleaner. But don't do it that often so....

I wouldn't be surprised to see EFI weed eaters and lawn mowers in the

next few years. The microprocessor would cost less than a buck. The

enclosure and connectors will be more of the price than the chip.

The only trick I see is how you power the chip and injectors until you

get it going. If this is an electric start lawn tractor, that is not

an issue.

They're already out...

Those are on the high end of "small engines" but that is what I am
talking about.


But the EFI ones are not in the chain saw/mower/weedeater size.

If the manufactures could develop some type of standard, it seems a rechargeable battery, such as a
LiPo, could provide the energy. Or, a plug in to a cigarette lighter, just to get the chain saw,
mower, weed eater, whatever, started.

Actually you could probably do it with a capacitor, like the old
Triumph trick. Then you don't have the battery problem at all.
Yank the cord a few times with the ignition off to charge the cap,
turn it on yank and go.


"Super" and "Ultra" capacitors are becoming more common in many low
current applications and can replace a battery in many cases. I first
learned about them when a company up here in MA started making under
saddle acoustic guitar pickups using a Super Capacitor instead of the
traditional 9 volt battery to power the pickup's pre-amplifier (located
in the guitar). The pickup is supplied with a small AC adaptor that
has a standard, 1/4" guitar plug on it's output. You simply plug the
plug into the guitar's output jack, plug the AC power supply into the
wall, wait for 60 seconds and remove. The Super capacitor typically
powers the preamp for about 40 hours of continuous play. When
discharged, you just repeat the process. I had guitars that I
initially charged and two months later they still played fine without a
recharge.

I think some of the crank type flashlights also use Super Capacitors.
Again, how long it takes before a recharge is required depends on the
current draw.

I doubt the super caps would have the current to fire injectors. They
are really meant for long term, low current loads.
In this case you need something that gives you a high current, short
duration shot and only has to hold the charge for a few seconds to
start it. Once it is going that is more like milliseconds. You would
not need much of a charging coil in the stator to keep things going.


Gee. Diesels got along fine without electricity for years.
Fuel + Air = Runs (assuming you can turn them over with a crank)

It is like painting. I know how to do it but I hate it.

If you don't have access to a hot tank, "rebuilding" carbs can be a

frustrating exercise. There always seems to be one passage you don't

get completely clean and that is usually the one that caused the

problem in the first place.

Yep!

You do not want a hot tank on aluminum. Use Chem-dip or another aluminum
cleaner.

I am not sure what they had in the tank but they called it a hot tank
and a carb came out looking brand new.,

Hot tanks where they cleaned blocks would eat aluminum. Made nice bubbles
in the tank. The engine block tanks used Caustic Soda.

We had a gas pony engine to start the diesel on the Cat on the farm. That worked, if you could get
the pony started. That was the 'crank'!
