Mutu, we have a big problem here. First you have posted on a thread that is six years old. May get little action. Second we have no ideal which Husqvarna tractor you have and what engine is in it. If you really want help please do the following.
1. Start a new thread, it doesn’t matter on which forum, the moderators will move it to the proper one.
2. Include in that thread the following.
A. Model and serial numbers for your tractor.
B. Brand, and all numbers off the engine. Different manufacturers use different number sequences.
C. Describe to the best of your ability what your problem is.
D. Describe to the best of your ability what you have done to solve the problem.
You must paint us a picture of what you have and what is happening. Remember we are not standing next to you and our ESP is down since Trump took office. There are members from all over the world willing to help you, but you must help us first.
