Happy New Year. If anyone can help me I'd appreciate it. I have a Husqvarna 435 and its been running great for about a year now. Just recently though it bogs down and stalls whenever I try to make a horizontal cut. Like when I'm notching a tree. Vertical bar will run all day with no issues. Turn the bar to the horizontal and after about 20 seconds it bogs down and stalls. Changed fuel filter and inspected fuel line but still does the same thing. Any Ideas?
