Bill, thanks for the input. In the past week or two I watched many/most of the Joe Pace videos on Youtube and now understand that without a Pressure/Vacuum Tester I am "driving in the dark" to fix this blower. I plan to buy a MityVac so that I can diagnose this properly --but it might be a...

This is the same Blower that I solved the No Spark problem on back in October 2019. I was given for free this Husqvarna 125BVX handheld blower that defies almost every fix I can think of. Failure symptom is it runs for 30-60 seconds after priming via bulb, then it quits unless i periodically...

Been a while since i got back to working on this. Changed spark plug, it ran for a few seconds then quit. Installed new carburetor. No go. Seems like it is getting no spark again. Don't see evidence of pinched wire. So (before i swap parts again blindly, i.e. without doing proper...

Splined carb adjustment tool arrived. I was able to adjust (mainly the Low jet) to eliminate the problem whereby engine cut off/died unless on Half Choke. New problem is the engine bogs down an dies after running under load (edging) for 3-4 minutes and engine won't restart until it cools down...

I had replaced the fuel filter already when I replaced the fuel lines. Just now I replaced the Primer Bulb although the old bulb seems perfectly good. I also adjusted using an electrical connector (Butt Splice Crimp Connector)--the blue 14/16 Gauge connecter was the best fit. However it...

I cleaned out the wire screen it was maybe 10-20 percent clogged. I soaked the carb in isopropanol and blew out what passages were accessible. Diaphram looks good. What are the jet default settings? Also what is the trick for turning the jets without a special tool? IF I recall correctly, a...

Attached photo shows the tube that seems to be clogged.

I fixed/replaced the 2 loose fuel lines and the bad Intake Manifold gasket. I also soaked the carb in 70 percent isopropanol. No change, It still runs only when on Half Choke. I think a new carb is next step because one brass tube going into the carb (the tube on the Purge Bulb half of the...

Manic84, thanks a lot for your input. I will try to use 3/16 OD 3/32ID fuel line and not go up in size if at all possible. The old lines are very yellowed/aged--I am surprised they are not cracked (I tested by plugging 1 end and blowing into the other end). Yes the old lines appear to have...

Wait!! I think I found the solution. There is a Fuel Line size that I haven't used before (or at least not in recent memory)--it is 1/4 O.D. and 1/8 I.D. The 1/4 inch O.D. is 16/64 which I suspect will be a tight (but good) squeeze in a 13/64 hole. Unfortunately my local hardware store is out...

I bought a Husqvarna 128LD Edger cheap at a Thrift Store. Apparently a previous owner/"fixer" drilled 2 oversize (13/64) inch holes for Fuel Lines in the Fuel Tank. All normally-sized Fuel Line material that I know of is too small (on Outside Diameter) for these holes. To get it running...

I was wrong, it is not a Walbro, it is marked " Zama China W40A 502A 118". probably a Walbro knock-off? Yes the spark plug is RCJ8Y, I will buy a good quality 3/4 inch wrench. I did some diagnosis today. I noticed that the primer bulb fills up around 3/4 to 7/8 when pumped 10times, but it...

I was given a 128LD with LE720 Edger attatachment. Previous owner was frustrated with it but I don't know how/if they trie to fix it--i.e. no Repair History given to me. First thing I did was to dump the fuel tank into a glass jar (yep, small amount of water was found) then refill the fuel tank...

I always use an Adjustable Gap Spark Tester. This is better than testing using another sparkplug because it yields quantitative measure (I learned this the hard way working on outboard motors). I will look for pinched wire. Thanks for the input.

My Husqvarna 125B won't start, has No Spark. I haven't yet disassembled to look at Kill Switch but while I am in there I will check the Flywheel-to-Coil gap, Coil Resistance and possible Sheared Flywheel Key. 4 Questions: 1) Should Flywheel/Coil Gap be the usual Business Card dimension? 2)...

I removed the clip and reassembled just enough (skipping Chinese jigsaw puzzle throttle) to check spark. Good news--we got fire! Tomorrow I will reassemble with throttle but without clip, just enough fuel in tank to cut some small limbs. This will test my buddy's original failure symptom--saw...

This saw is driving me crazy! The clip is definitely touching ground metal "by design", or is this are assembled incorrectly? See attached 1st photo--with the points fully open (I stuck a bit of paper in the points gap) I get zero resistance across the meter probes. It seems like everywhere I...

I believe I am getting closer to finding the smoking gun on this. The points seem fine--they are clean and seem to have the right gap/closure when I rotate the crankshaft. However, with Ohmmeter I determined that the Clip is connected to cylinder head, muffler etc. Whereas I would think the...

Today I removed the flywheel, but this design still has me "stumped". Can anybody shed light on this? This metal (aluminum?) Split clip seems to be always connected to the coil. And i don't see that sliding the Stop Switch will move thus Split Clip. Any help will be greatly appreciated.

HarleyT, thanks very much for the photos, this helps a lot. Tomorrow I will try to remove the flywheel to debug further.
