Can you confirm whether it is actually getting fuel to the carb? Try =

The carb is getting fuel. I can see it in the fuel lines and it pumps using
the primer bulb.

The symptoms are identical with the old and new carb. I can't see the end
of the fuel line but the only remaining fuel issue could be that the new
fuel filter (a pumice stone-like thing on the end of the fuel line) could
be restrictive. Working against that theory is that it did the same thing
with the old fuel filter.

I don't think the problem is the fuel system. The problem is...what's left?
I swapped the spark plug just to do it.

It's a four-cycle engine. Might the valves (like the intake and exhaust
valves in the head) come out of adjustment? This condition has been
developing over more than a year...perhaps the valves are slowly coming out
of adjustment?

I don't know what conditions un-adjusted valves cause. I can't think of
what else it could be.

Howdy,

You mentioned that the choke didn't seem to do anything... Is there
something broken in that setup, so that it's messing up the air supply?

If the valves have tighened up, which is normal as things wear, they =
won't be sealing and you won't have enough compression to light off the =
charge, or when it does light off it's leaking out instead of making =
power. Is there an adjustment available on this engine? I don't know =
tiiny 4 strokes at all. I would think they'd build it with more =
clearance than woul devery be used up by wesr. Can you do a compression =
test on the cylinder? Leakdown test? Does it feel easier to start =
(assuming a pull start) than when it was new? A leaky valve would make =
it feel easier - the more leaky the easier it would be.

You checked the spark plug wire for cracks? Can you try it in the dark =
and see if the spark leaks out of the wire anywhere?

Check that the exhaust (little screen filter) is not plugged up with
exhaust crud.  Can cause those symptoms.

There is a manual for a Troy-Built 4-stroke backpack leaf blower here:
https://www.leafblowersdirect.com/manuals/TB4BPEC_manual.pdf

Around page 13 they detail idle speed adjustment, rocker clearance, etc..
Don't know if it your model, but might be a good place to start.

If the valves have tighened up, which is normal as things wear, they won't
be sealing and you won't have enough compression to light off the charge, or
when it does light off it's leaking out instead of making power. Is there an
adjustment available on this engine? I don't know tiiny 4 strokes at all. I
would think they'd build it with more clearance than woul devery be used up
by wesr. Can you do a compression test on the cylinder? Leakdown test? Does
it feel easier to start (assuming a pull start) than when it was new? A
leaky valve would make it feel easier - the more leaky the easier it would
be.

You checked the spark plug wire for cracks? Can you try it in the dark and
see if the spark leaks out of the wire anywhere?

The symptoms are identical with the old and new carb. I can't see the end of
the fuel line but the only remaining fuel issue could be that the new fuel
filter (a pumice stone-like thing on the end of the fuel line) could be
restrictive. Working against that theory is that it did the same thing with
the old fuel filter. 

I don't know what conditions un-adjusted valves cause. I can't think of what
else it could be.

I had a leaf blower stop running a few years back due to a bad ignition coil. Have you verified you’ve got spark? I don’t see that specifically mentioned (yes, you did mention the spark plug)

Update for those of you sadistic-enough to keep reading: the intake valve
was...loose? Open? The gap was too wide.

The spec is .003 to .006 intake and exhaust - my smallest feeler is .006. I
adjusted it to be tight on .006.

The hard start is totally fixed. Starts great now.

Still won't accelerate. Opening the throttle bogs it and it'll die if you
don't let off. Curing the starting issue seems to have thrown the bogging
issue into starker relief.

Exhaust can is clear. Gas is new. Air filter is clean and freshly oiled and
removing it entirely changes nothing.

I am unfamiliar with valves making something not run--my experience is
either on Ford V-8s or a Triumph 1147 I-4, or Honda or Kawasaki SS
motorcycle engines, none of which ever had issues with the valves. This
thing's valves are literally just adjusted with a 5/16" nut--there's no
locking nut. Is it possible that making the intake or exhaust valve tighter
or looser could cause something like this? Like should I shoot for one end
of the spec of another?

Last thing left would be the coil like Tom suggested. There's no mention of
it in the owners manual and I don't see it in a parts search so far, but I
started with Amazon.

Seriously. I have built--from rusty blocks--a Ford 289 and 390. A Triumph
1147 that came in several Tupperware bins. More rebuilds of CBR600 and
ZX750 engines than I like to think about.

A leaf blower engine is threatening to best me. I want to back over it with
the truck just to make it disappear. I think I'm looking for moral support
here.

Worn cylinder or piston? Bad valve entirely? I could dig out a compression
tester, but there's no spec for it in the manual anyway. I'm kinda at a
loss here.

If the intake valve clearance is too large, the valve does not open
sufficiently and the engine can't breathe in the fuel/air mixture. If
the intake valve clearance is too small, the valve may not close
entirely and the engine will not have compression - no running - or the
combustion gasses may come back through the intake system - backfiring.

If the exhaust valve clearance is too large, the valve willnot open
sufficiently and the engine won't be able to get rid of the burnt
gasses. If an exhaust valve clearance is too small, the valve will not
close entirely and the engine will have insufficient compression - no
running - OR (even worse) the engine may run but the valve is never
closed long enough to cool its face off and it will burn, as will the
valve seat.

I don't know this engine, but if a 5/16 nut is all that secures the
valve setting, it might be worth putting a drop of blue LokTite on that
adjustment after figuring out just where it should be so that it doesn't
"adjust itself" while the engine is running.

It could be rings or burnt valves, but I would expect hard starting in
that case. The coil is likely under the flywheel, as part of the magneto
ignition system. That is typical of small engines. To access it, you'd
have to pull the flywheel which is a right pain, so testing the ignition
system first would be wise.

Hope this helps,
Donald.

and put in your model number (I picked the first choice for the TB4BP
because I don't know your exact model number) and poke around for the
engine parts.

Small engines are just like large engines, but smaller :-). They tend to
be more finicky because there is only one cylinder and if it gets
flakey, there is no one else to take up the slack.

Howdy,

The other day, I finally got around to selling the extra battery powered
string trimmer I have, since I switched all my stuff to the red brand.

Cheapo Black and Decker.  Last used probably 5 years ago?  Maybe more.
It'd just been sitting there with the battery in the charger the whole time=
.

I clicked the battery into the tool, pulled the trigger, and it spun right
up, just like it always had.

My life is better with less small engines in it.

Mark
