I’ve got a Makita 4 stroke handheld blower that’s been bogging down really badly when I throttle it. I always run non-ethanol, but I figured maybe the carb had some junk in it so I ran some seafoam through it. That didn’t help any, so I replaced the carb. No help there either. I pulled the spark plug and it was clean, but I scuffed it up anyway. Still bogging down.

Any ideas? Thanks in advance.

Pin hole in your fuel line or primer bulb?

Makita 4-stroke equipment seems to have issues. I came across a Makita 14" power cutter for what seemed like a great deal but after reading reviews and looking at comparison videos it was clear that they can have serious issues even with perfect maintenance. Their chainsaws (rebadged Jonesereds before they bought the company) are excellent though.

Whenever I have trouble with my equipment the first thing I check are the filters..air and fuel. Then I check the muffler..it could be clogged and causing backup. Fuel lines are good shape and the grommet is not cracked. You looked or changed out the rest of what I was going to suggest to look at.

Fuel line, filter, and bulb were changed with the carb. I’ve also tried running it without the air filter to see if that was the issue. No dice.

check GAS CAP TO SEE IF IT HAS VACUUM, IF SO YOUR VENT IS CLOGGED

Have you checked the coil wiring? TCI setup so you should only have the high-voltage wire. Weak or incorrectly timed spark would cause running issues.

I’ve run it without the gas cap and same deal.

Could you explain the coil wiring in more detail? Can I change the timing?

Timing is fixed but a TCI-based ignition setup generally only has one wire that goes to the spark plug. If something has damaged that wire, there is an internal break, or it isn't making good contact with the plug then you will have running issues. Can also have problems if the coil has moved in relation to the flywheel due to loosened hardware or there is enough corrosion between the magnets and coil.

So basically I should just throw this thing away and buy a Stihl.

That's exactly what I did.

I thought... 4 stroke. Cool. No mixing. Of course, it's underpowered, weak and generally an all around not good blower.

Unpacked my Stihl and when I took the box to the curb on garbage day, I put the Makita beside it. Somebody got it before the garbage folks came. Lucky them.

Literally my thought process exactly. I could even deal with the underpowered part just because it's general residential stuff, and I don't have to mix gas. I'll be doing the same here over the next couple days. I've got a Stihl dealer right by my house. You got the BG50 or the BG56?

BG56. I run either TruFuel or Stihl MotoMix in it. I got a small can of Trufuel, when it ran out, I got a big can of Stihl Motomix from the hardware store. Haven't had one single issue.

I called my Stihl shop this morning and the guy told me I'm the second one this month calling with an issue about a Makita 4 stroke ha.

Any regrets with the 56 instead of the 86? I will run the Stihl mix in it probably. The guy said if I do that, it doubles the warranty.

No, not terribly hard to check out. Use a business card to check/set the clearance between coil and flywheel magnets. Maybe some fine sandpaper if there is any rust to clean off. Make sure the spark plug wire doesn't have a worn spot and it making good contact with plug inside the boot. Remove the plug, keep it attached to the coil, ground the threaded part of the plug and pull the starter to see if you can see it spark.

Roger. I'll give that a shot before I pull the trigger on a new one.

why are you guys running handheld blowers? Strap on a backpack one and you'll wonder why you haven't this whole time.

I have an Echo residential model. They're not expensive at all LINK

Because it would literally take me longer to strap the backpack on than it would to blow off my very small driveway/patio.

Because man....every now and again I just want to feel some power in my hands and blow some shite around. It's a delicate balance.
