Sorry, but we are not a trading company
Looking for a Kawasaki FH531V-ASO engine for Husqvarna riding lawnmower. Grateful for help in locating. Thank you
I’m looking for your engine spec sheet chart
I am trying to find a diagram or image for the correct choke linkage hookup between the carburetor and the cable transfer mechanism. It fell off during a carb replacement and for the life of me I can’t figure out how to make the proper connection. Looked everywhere online but no luck. The only place it actually fits appears to be the throttle lever. Any help would be appreciated.
Hi there David, just wondering why you replaced the carby? Was it because it was surging at idael cause mine is doing that now, when I’m mowing it does it a little but when I stop to empty the catchers the motor surge up and down. Today I’m replacing fuel filter, oil, oil filter also the two spark plugs. Not sure on what else I can do with out going inside of it. What do you think??? Any help would be appreciated cliff.
Fh531v. Compression left 145psi Compression right 130psi. New coils good spark. Only runs on left cyl. Flooded spark plug on right. Help please
I have a Kawasaki motor FH531V-DS06 dated 2007 in my mower. The odd thing is, that NOWHERE on the Web can I find reference to that SPEC for a FH531V engine. The sticker clearly states it. The Web shows “BS06”, but no “DS06”. What’s wrong?
I want to get the correct engine manual but cannot make a move until I am sure of the SPEC.
What a waste of time no one gets back to you or even replys
Thank you very much! You were a big help getting all the information I needed to get the right parts.
I do have a question, throttle isn’t attached to anything besides the cable to the control plate. Can’t idle down ? I have the governor on, but what connects the two?
