Top 20 Husqvarna 28cc Hand Held Blower HVH 125B Questions & Answers

Remove plug, leave plug wire on plug wrap a piece of conducting wire around the plug base and other end of wire wrap around metal part of engine pull starter and see if you have spark. You may have to darken area to see spark. If you have no spark probably bad coil or could be just switch has gone bad.

Just go from the fuel tank straight to the carb and the primer. The pipes are a set length so you don't have to worry about threading it all around the blower.. just take the most direct route from the tank to the carb..!

check primer bulb for cracks and leaks . check hose into the fuel tank for cracks and leaks pull the carby apart and replace stiff diaphragms.

unit is running lean. The lo is closest to the crankcase. Give the lo a half turn out.

Either the return line to the tank from the primer has a hole in it, is broke, disconnected; or the diaphragms in the carb are stiff and the unit is flooding

I use the back of a pack of matches an that worked but I don't know what the gap of that is but worked on my chain saw!

Is the gas fresh or old that you used. Since this brand new, it's under warranty. If you've had it for a few days, return to the store from which purchased it. It should run right out of the box without having to work on it.

look for bad safty switch

The fuel line should be replaced

Have you checked the Flame Arrester in the Muffler. They clog easy and engine can't push out exhaust.

how long will it run? 30 seconds 10 min.pour ot the gas & look inside the fuel tank is it dirty?is the filter still hooked up to the supply line. Mine had fallen off [worn out] I replaced with new fuel lines and still had a 20 sec run. It was flooding let me know

return hose from the carb goes there.comes from primer bulb on carb

1. Check the pipes to the primer bubble haven't been swapped round, as it sounds like its pressurising the fuel tank.2. Also sounds like the fuel tank vent could be damaged, this allows pressure to equalise in the fuel tank. Generally it allowa air in but not out the tank, If fuel is exiting the tank then this could have been damaged.

I know the video shows a chainsaw but its the same principle.

I have a Husqvarna 125B same problem. Turned out to be a bad gas cap. Doesn't vent properly and starves the engine. I took the gas cap off of my Huqvarna weed eater and put on blower and blower worked fine,

how does it run with out the air filter in place? maybe its plugged and need's replacement

Check throttle linkage is still connected to the carb

Will it start again after you let it cool off? Run it till it quits then immediately remove the air filter and cover and give a quick shot of carb cleaner into the carb and attempt to start. If it wont start on a prime but will start later after you have let it cool, then does the same thing ( dies after 10 or 15 minutes of use) then it is likely the ignition module going bad.I suggest you find a serviceing dealer to verify that the module is failing. Husqvarna warranties thier ignitions for life on most models.
