Pulse line on Rotax 582 mod 99

in 2 Stroke Technical Questions 12 years ago
My Rotax 582 mod 99 has a fuel "pulse line" running from the fuel pump to the engine block.

Can anyone tell me what the pulse line does?

    This "pulse line" is what operates the fuel pump. As the vacuum "pulses" from piston movement, this vacuum variation pulls and releases a diaphram which "pumps" the fuel from the fuel inlet hose and to the carb.

    Alan, thanks got the clear explanation.

    I wish I could find a two stroke engine book that explained these things. Or even better, a book that explained these things as they relate to the Rotax.

    Mike I know how you feel...2 strokes can be a mystery if you just used to auto engines like I was,

    Have a read through some of the articals on the web page on this link,

    http://www.800-airwolf.com/articles.htm

    Lots of information to be learned there....was for me the first time I started reading them,

    Its good that you want to learn as 2 stroke need a curtain care and understanding to be reliable which should be no trouble as long as you have that knowledge,

    Another good web site with lots of very useful videos is this one,

    http://www.eaavideo.org/channel.aspx?ch=ch_hints_general

    Just have to go through all the categories to search them out.

    Like Nick says, go to the california power systems website and look for Tech Articles under the tech info tab. Just about anything you need to know is there. You can also buy from CPS the Rotax 2 cycle repair manual. For some strange reason, it is not among the manuals offered under the support tab on this site, and it is the official rotax manual.
