sorta-OT Small Engine stalling
 

Hi, guys:-

I have a relativley new Husqvarna 130BT 29.5 cc 2-stroke backpack leaf
blower and it has a stalling problem- runs for some time (maybe 30
seconds or maybe 5 minutes) then slows down and (usually) stalls or
sometimes speeds up again. It pretty much restarts immediately with a
pull. Fresh gas properly mixed with 2-stroke oil 50:1 as recommended.

Cleaned the gasoline pickup, tried loosening the gas cap in case the
vent was plugged.

Any ideas?

There's apparently no manual choke (the usual primer bulb) but a lever
that has open and closed on it- it really only runs continuously in
one position (and the compression seems to be gone in other position).
The manual (such as it is- it covers three models) is silent on what
should be done with it.

It certainly points to a plugged vent condition. Are you sure you
loosened the cap enough to clearly vent the tank?

Loose carburetor screws might cause that. The flange could warp as
the engine warms and cause a lean mixture and stall.

I had this problem twice occuring to a 4 stroke Ryobi weed eater. The
problem was in the carb. In both cases I carefully took apart and
cleaned the carb using the carb cleaner that comes in a spray can and
has that litle red tube that is really good for blasting the cleaner
through tiny passages. When I looked at the carb internals I could not
see where or what the contamination was except that there was a sort
of brownish residue coating various parts of the internals. All I know
for sure is that in both cases the thing would start losing power and
then die. I could do the restart thing a few times but then the
engines would only idle, and would die as soon as I pulled the
throttle trigger.

I was afraid of that. Bad memories from working on lawnmowers. I'll
take the carb apart and blast it with carb cleaner, prob next weekend.
New carbs are too pricey to consider ($130+ with shipping).

Does it pump gas through the black hose (with filter attached) and
return unused fuel through the clear hose that's just hanging in the
tank?

That's the way most of them work . I've had pretty good luck finding
replacement carbs on ebay for my small engines at around 20 bucks or so .
Looked for yours , found only complete blower units and a couple of carb
kits plus some misc parts .
Before I took anything apart though I'd run some seafoam or B12 chemtool
thru it . Sounds to me like intermittent plugging from gunk getting loose in
the passages .

We have mud dauber wasps around. They like to build their mud-nests in
the exhaust, plugging it quite effectively. I tore the carburetor apart
and cleaned it twice before it finally dawned on me that it didn't
sound right when it did run. Felt really stupid when I spotted the
mud-dauber nest. Poked it out with a screw driver. Got so I would leave
something stuck in the exhaust port so they couldn't build a nest
there.

Just something else to look for...

If you really don't want to mess with it you could take it to a small
engine repair place. Surely there's someone up there in the wilds of
Canada that would do such work.

(We have two local places around here that are both excellent -- so I'm
spoiled).

Be sure to look at the gasket to see if it shows any signs of dirt
being sucked in past any portions of it. Note if either of the screws
was loose, too. G'luck!

Through the years I've gotten away from ethanol for mowers and 2 stroke tools....anything that may sit for extended periods. Some of the stations sell 100% gas for a premium. Others I know use additives to overcome ethanol use. I've had the fuel and return lines deteriorate thru time to the extent the intank filter came loose from the line. A severe crack or break is pretty evident...a smaller one could cause the intermittent problems you describe.

The local rental place only uses ethanol free gasoline in their
engines and requires customers to do the same. Though I don't know how
they would check. I switched to ethanol free about two years ago and
have found that I have less trouble starting engines after they have
sat for some time. And interestingly there is less stuff floating
around in the bottom of the clear float bowl on my Gibson tractor.
There used to always be a little rusty or brownish water in the float
bowl but with the ethonal free gas I don't see this anymore.

A lot of the small 2-strokes use pressurized tanks, so loosening the cap
is the wrong strategy with them.

Those that work that way often have a diaphragm pump that keeps the
pressure on the fuel; sometimes part of (or at least acting as a base
for) the carb. A sticky ball valve in that pump could cause what you're
seeing. Some use flapper valves -- more likely to fail sooner and
outright, but less likely to stick.

Okay, I burned off the spark arrestor with propane torch (it was about
15% fouled), disassembled and cleaned every bit of the carburetor, and
replaced the fuel with Shell's best grade with 0% ethanol (and 1:50
2-stroke oil, of course) and cleaned the fuel filter again and it runs
like a top. The choke even does sensible things again. Thanks, all.

A fair percentage of the time disassembling and blowing out the carb
solves problems even though I don't find a visible fault. A few times
I've found gelled gasoline clogging the main jet.

Goodonya, mate. It's too bad, though, that you didn't think to try
running it in between each process to figure out which was the true
culprit.

Chances are high that it was the carb, but I really like to know those
things with my own equipment, knowwhatImean,Vern? It can save time
the next time around.

the next time around.

Larry, I actually did between several of the processes, but it was not
definitive- some things *changed* for the better but didn't fix the
problem 100% until I got to the end.

Next time if it acts up similarly I will follow this sequence:

1. Clean/replace fuel filter (and fresh fuel with 0% ethanol if
there's any question)

2. Check/clean air filter and spark arrestor (they're both easy and
fast)

3. Disassemble and clean carb completely (replace gaskets and
perhaps check valves if old)

(of course if it had seen a lot of use, I'd check the spark plug too
and check fuel lines for cracks etc.)

Goodonya, mate. It's too bad, though, that you didn't think to try
running it in between each process to figure out which was the true
culprit.

Chances are high that it was the carb, but I really like to know those
things with my own equipment, knowwhatImean,Vern? It can save time
the next time around.

Oh, good.

Yeah, that points to lots of things contributing to the poor running,
but it sounds like the major contributor was a clogged carb.

Excellent list.

Okay, I burned off the spark arrestor with propane torch (it was
about
15% fouled), disassembled and cleaned every bit of the carburetor,
and
replaced the fuel with Shell's best grade with 0% ethanol (and 1:50
2-stroke oil, of course) and cleaned the fuel filter again and it
runs
like a top. The choke even does sensible things again. Thanks, all.

A fair percentage of the time disassembling and blowing out the carb
solves problems even though I don't find a visible fault. A few times
I've found gelled gasoline clogging the main jet.

All the more reason to put the ethanol into people and keep it out of
small engines!
