Question about Husqvarna Garden

1 Answer

I purchased a new Husqvarna 580bts blower. I am unable to run it with the choke closed. I have to run it with the choke open all the time. I have run it for 2 hours so far. What might cause this to happen?

Choke open is the run correct position. If you close the choke, you cut of the air flow to carburetor.

SOURCE: Leaf blower will not run good. Only runs at full chike or half ch

If the trimmer is more than 3 to 4 years old, you may want to replace the carburetor parts, (new carb. kit). It also depend on the amount of use.
If it is newer than that, then you will need to disassemble the carb. and spray with carb. cleaner. Make sure that the small screen in the carb. is free of debris. Use a Den tek Brush,
(, to clean the small portals in carb. Reassemble and start.
If you need further assistance, just let me know.

SOURCE: My leaf blower starts up fine but when I advance

Sounds like a carb issue. Try spraying carb and choke cleaner while it is running. If that does not help may be remove carb and clean and rebuild it. My weed eater does same thing and I get it running and then spray it down. It takes a couple of sprayings but it helps.

Good luck

SOURCE: mb 3200 gas leaf blower will start when choke

The carburetor could need rebuilding or you have some bad gas. I would mix up some 2 cycle oil and fresh gas from the station. I would try the new fuel mixture first.
Good Day.

Sounds like you will need to clean your carburetor, or rebuild it. Could be some debris in the jets of the carburetor. If the blower is over a couple years old, then I also recommend that you buy and install a new carburetor repair kit, because the diaphragm will get hard and that will cause it to be hard to crank and not run at full speed. Hint: When you clean your carburetor and remove the jet screws, count the number of turns it takes to seat the jets from their original position. That way when you go to put the jets back in, you know how many turns they were in/out. Please rate me, Thanks Good Luck, I hope this helped

Motor will start but I have to manually hold the choke open until it warms up otherwise choke closes on its own

Yes this is the semi automated startup process. If the fuel is bad(old) or the carburetor has residue restricting the fuel passages the engine will run lean requiring some enrichment.(choke) I suspect that the engine may be hunting when warm. Use carburetor cleaner along with a fuel stabilizer.

Check/replace the fuel filter.

Empty fuel tank and purchase some no ethanol from home supply running the engine will assist in cleaning the passages. When engine is running close the choke a fuel times to give the engine a poor mans clean out, Avoid disassemble of the carb with out having technical compliance.(these are delicate and susceptible to contamination).

Never leave fuel in the engine when in storage. Ethanol gums up the fuel passages.

Hope this helps?

I just bought a Husqvarna 150 BT blower today. It will not run when I open the choke back up (open / off choke). It only runs in full choke (choke close position). I let it warm up for ten minutes or...

I'm assuming this is a new purchase. You may want to take it to a dealer and have the carb. fine tuned. Sometimes they can be a little off right out of the box. Hope this helps.

Will not operate with choke full open

It sounds more like the high speed jet needs to be opened. No engine will run with the choke on. Open it up, find the little screw labeled high or fast, you have 2, one low or slow, If opening it up doesn't work, try closing it, turn it a very little bit at a time to see what it does. Hope this helps.

New honda hrr auto choke hard to start

sounds like it may need the carb clening out, but it could be the auto choke not closing when cold. there was an issue with some of the early auto chokes on the gcv135/160 engines so check to see if the choke flap is in the closed position when starting from cold, run the engine for approx 10-15 minutes and see if the choke flap has opened fully.leave it to go cold and see if the choke flap has returned to the closed position

Can't restart my new husqvarna 450 chain saw after a little bit of time using it. i followed the instruction manual both times.

The manual may not be clear, read warm line 3 below, read it again. The 450 manual I read says something similar under warm start. Are you opening the choke after turning on the ignition? Before pulling the starter rope? Flooding is the most common hard start problem with 2-cycle engines. If you are opening the choke I recommend you contact Husqvarna for guidance. They will likely send you to a neighborhood dealer, gratis.
Start Procedure

  1. Ignition on/off to on.
  2. Set compression release – optional step even if saw is equipped with a compression release.
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4).
  4. Set compression release – optional step even if saw is equipped with a compression release.
  5. Push (open) choke pull starter until it starts. (usually first pull).
  1. Ignition on/off to on.
  2. Set compression release – optional step even if saw is equipped with a compression release.
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull).
