The one thing you didn't check was the kill switch circuit. It might have had some little piece of crud partially grounding it out (as indicated by the inconsistent spark in the beginning) that eventually broke loose without you knowing while you were fooling around with it, allowing it to start later

4:18 the reason your gauge showed lower compression than expected is because you used the attachment for the compression tester for the smaller spark plug hole. You need the Schrader valve to be at the absolute end of the tester, or else the extra volume will reduce the compression, even if it was just a little bit. I've struggled with this in the past before I realized this

Good findings. Ebz8050 Takes 3 primer pumps, put on choke and then 3 good pulls and it always starts on the 3rd pull. You can take it off choke as soon as it starts. It’s been a great blower. Put on a eBay/China $12 carb on it last year after 6-7 years of ownership with no other issues. I’d buy one again.

I had something similar happen. Got a brand new ebz7500 at work. Was loving life, breaking it in and all that. Got low on gas 1st tank went to grab some and came back. Blower died but didn’t run out of fuel. The ignition coil failed within the 1st couple hours of use according to the shop. I didn’t get the chance finish breaking it in…. Boss gave me another new blower the next day and that one has been a champ for 3 seasons. Was super weird to say the least.

Neon spark testers are only a quick test, you really need a spark gap tester to see how far the spark will jump.

In the past I used to make such a distance "jump" tester with just a wooden block, an old sparkplug without internal resistor and two nails. One nail is fixed on the block and jammed between de electrodes of the sparkplug. The sparkplug boot is then easily connected to this sparkplug. The other nail can slide and is connected to a wire and simple clamp to ground. You cut away the wood surrounding the nailtips. You could set the distance between the tip of the nails. Indeed worked like a charm and I could test (mostly) questionable moped ignitions by using a drill and socket to spin the engine. This way you can test the induction strength of the coil on the actual setup and detect faulty coils. Most times if coils are bad the colour of the spark has an "orange" tone to it and or is hardly visible. I think that a distance of at least 8 to 9mm is ok

But still won't start even though the coil/flywheel gap is spot on. Next step: ground the plug; hmm, there is no spark. Thus, I have ordered a better gap-type tester ... and a new coil. I have used the HF tester for years and it always seemed to be a good ignition indicator. Because of this experience on the Echo, it is revealing to me that it can register some juice, yes, but it can also be misleading.

it's worth a shot.

Not for the issue you had, but as an FYI for later. These Redmax blowers, it’s very common for both the cylinder head and intake manifold bolts (4) to loosen or check as loose. When either the intake manifold or head gasket leak, if will cause various mysterious running issues. As a preventive measure when new, a good idea would be to put a white paint mark across the bolts and manifold and bolts and cylinder base, so with a quick visual inspection you can see if the bolts have loosened. However, the assemblies/gaskets may compress over time and thus the tension is released and although the bolt hasn’t turned, it would check loose when you tried tightening it. So, it still may be advisable to torque check these bolts periodically. Some other ideas would be blue thread locker, nordlock wedge lock washers (add 2mm to assembled height, may need longer bolt to maintain thread engagement), and lastly, safety wire bolt pairs to each other if you’re good with that sort of thing.

And I’ll add that if the cylinder bolts become loose, the gasket between the cylinder and crankcase will most likely fail. Once that happens, you won’t have the necessary vacuum to pull the air/fuel mixture from the intake side into the engine. If tightening these bolts gets you running, but the blower is still hard to start and then dies after running long enough to get fully warmed up, replace that gasket. It’s an easy job.

For a while, I was thinking that there was something wrong with the kill switch. I was thinking that the manufacturer had a faulty kill switch that was preventing the blower to start. Good detective work on your part. 🤔🤔🤔🤔👍🏿

I have a two copies of this machine or a rebranded version & i can tell you this much, mine won’t start with wide open throttle, to start i follow the manufacturer’s guide which i s to apply full choke no throttle, pull start until the engine starts & runs & when the engine starts to stumble, open the choke to fully open & the engine continues running, after a minute of warm up i can apply full throttle. I don’t own a single two stroke engine that requires any throttle to start & i own 8 different machines with various sized engines. Last year i had one of my Honda engined Toro Hoverpros that would run for a few minutes then die, it would restart each time but die again. Turned out it was the spark plug which was a resistance type plug, the resistor was failing & cutting out. A new plug immediately fixed the issue. A resistor plug usually has an R in the part number.

Once cold I start it up and it does the same thing. Only difference is it only takes 5 minutes to act up now. I have done the following. Cleaned the spark arrestor, replaced the spark plug, air filter, fuel filter, carburetor (OEM), ignition coil, and fuel lines. Compression is 127 (checked it right after it lost RPM). I also removed the filler cap thinking the vent was clogged. No change. Spark plug tip looks normal. Once RPM’s dropped I sprayed starter fluid into the intake and it still didn’t accelerate. It has me buffaloed. Any thoughts. I know I can buy a new one but the new ones like this are 2.5 lbs heavier and I’m like you, I want to find the problem. Sure would appreciate some help!

sure, have you checked the bolts that hold the cylinder to the block? have you checked the insulator between the carb and the engine? there might be a leak there. You given me a lot of information which I'm grateful for. That's why I'm leaning away from fuel, and spark, and towards an "air leak".

I have checked the cylinder bolts. I have made a visual inspection of the insulator but did not remove it. What could be wrong with it? What should I look for? Thanks for responding.

sure, I would start the engine and while idling, use a spray bottle of water, to spray water around the droplets, and see if the engine reacts to any water droplets that get sucked into a leak. I would normally recommend a different "spray" but I cannot because of liability. An air leak, after the carb, and before the engine would cause the engine to get more air, and not enough fuel, so the engine won't get to full speed.

What do you mean by "spray water around the droplets". Do you mean spray water around the insulator and see if the engine reacts to it? Have you ever heard of an insulator failure? If so, what happened? Are you saying an air leak can be different when the engine is cold and after the engine has warmed up? Thanks for your time?

@HomeGaragechannel

Жыл бұрын

sorry about that. spray around around the insulator or even the base of the engine where the gasket for the cylinder is. If the water droplets get sucked in, it will cause the engine to change speed, and you'll know there's an air leak there.

Have you tried putting a new spark plug? I have had some bad experience with those small thread spark plugs which can look good but still would foul and get wet pretty easy

I have a Poulan Pro blower. It was always running great. Then I ran out of gas. When I mixed a new batch of oil gas mixture it ran for a while then quite. Is my oil to gas ratio off. Or maybe the oil blend, brand (Pro select) was not good for my blower? Can you help?? It will start then quite.

even if you had too little Oil, say 60:1 or 80:1 it would take a couple of hours of running to really hurt it.

the leaf blower has a hard life since no one knows how to kick in the piston rings and stuff so they blast the hell out of it and when the piston and rings are gone they are like oh its toasted time to get a new one.

either a lack of fuel, or the exhaust is clogged.

It almost acts like a carb with a stuck open needle n just dumps fuel into the intake. Maybe that's what's happening when priming. Did you try starting it with the trigger pulled to give it max air flow n no choke after priming?

I've had coils still produce a spark but be bad. I had a saw push me to my limit of sanity and it turned out to be a factory new wire on the coil that was crimped to hard and was cut through but looked fine. The saw still ran but like it had an air leak. It's annoying because you have to check the gas,carb,spark,exhaust, gap, and timing several times before you can finally deduce the coil is shot has an issue or is shot. That blower is way to hard to start I'd be adjusting that carb and possibly even the airflow if that didn't work.
