    I have a husqvarna 225b handheld blower. This weekend i was replacing the fuel lines and noticed that the muffler screen was carboned up so i decided to remove it . Since then i have noticed that the blower is more responsive. Of course the exhaust is a bit louder and i noticed that the blower 4 cycles at w.o.t. like it should.

    It did not run this well even new. Are there any ill effects from removing the screen that i am unaware of ?:confused:

    I think they are called spark arrestors, someone correct me if I am wrong. We take ours off and throw them away as soon as we sign the ticket.

    the only possible damage that can result is a fire.

    The only concern i have is over-reving the engine

    The rpm's seem fine. I have a hobbs digital tach. I am going to check them tommorrow.

    I really do not see how the screen would effect rpms that much.

    The screen shouldn't affect the R's... But the lack of it will sure help start a fire on Property.. I clean mine pretty regularly.... I will say that keeping it clean/removing it seems to kepp the port cleaning ritual to a minimum...

    Serriously though, the number one cause of carbon/funk build up in a 2 stroke engine is prolonged part throttle/idling... It'll carbon them up in no time.... I had an interesting discussion with a Stihl factory guy at a Stihl school a few years back. He told me what their number 1 warranty problem was caused by...prolonged opperation at low speed/excessive idleing.... The guy was German and said that the problem seemed more prevalent here in the US, because ( he believed ) that consumers " Felt if they ran the machine at full throttle it would reduce it's life span " I tend to agree with him.

    BTW, sorry for the long story.. I can't get to sleep....
