Husqvarna 150BT 50CC Gas Leaf Backpack Blower 180 MPH - Manufacturer - Page 4 Questions & Answers
Husqvarna (GTH2448T) only starts if brake pedal NOT pushed. Thoughts?
May have the brake switch wired backwards. It appears to have 4 pins. I did some troubleshooting on a Cub Cadet recently and the brake switch had two contacts for a NO switch and two for a NC contact. The switch seems to have a tab to prevent installing it other than the "correct" way. I would take a look at the brake switch and wiring. Maybe somebody accidentally swapped the wiring pins in the harness for that switch. It's just going to need some investigation to see where to go next.
Husqvarna yth20k46 brake pedal, cruise control struck
I had my cruise control removed to solve the problem. The park brake would not disengage due to malfunction with the cruise control. When you engage the park brake, the cruise control locks to prevent it from being engage. If it is stuck, the park brake will not release. How do I know this? Had to put mine in the repair shop. The shop called Husqvarna and the shop was told the cruise control was a poor design and the best thing to do is simply remove it to prevent the same issue in the future.
4 stroke ride on mower had 2 stroke fuel through it
The only basic difference between 2 stroke and 4 stroke fuel is that you add a measured amount of 2 Stroke oil the the fuel. What issues you get will depend on how much 2 stroke fuel you actually ran through the engine. A small amount like 2 or 3 minutes of running time won't do the engine any great harm. You said you replaced the fuel for fresh 4 stroke. Assuming you only ran the engine for a couple of minutes you can safely run the engine AT IDLE to burn off the 2 stroke fuel. It will blow grey/black exhaust for a while but this should thin out and disappear as the 4 stroke fuel gets into the system. Once the exhaust gas clears turn the mower off and give it a full service, Fuel filter, oil filter, air filter and spark plug then you should be good to go.
Loud pop when started in free wheel mode on accident
That is a good question. It could have been a spark plug. Have someone look at it for you. A fuse that goes bad will not make a noise or a give out a bright light. It could have been a backfire from the exhaust. Will it start? If so, then it was not the spark plug.
Why do my husqvarna chainsaw lose compression?
What model chainsaw is it? The most common reason is not enough oil in the engine. Oil lubricates but it also has a cooling effect as well. Is your chainsaw 2 stroke or 4 stroke. A 2 stroke engine needs a measured amount of two stroke oil added to the fuel to prevent problems like this.
A 2 stroke will run without the oil in the fuel but it damages the engine if only used that way.
