View Full Version : Kawasaki FH430V Loping Problem

05-24-2009, 09:29 PM
I recently purchased a 2004 eXmark 36 inch Turf Tracer HP that had a Kawasaki FH430V 15HP engine. At low rpms the engine sounds like it is going to die at higher rpms the engine runs fine. The mecahnics at a local dealership called this "loping." They first suggested that I take off the carborator bowl and clean out any debries. I did that but the problem continued. The dealer mechanic then said that there is a jet on the top of the carborator that needed cleaned. I took the carborator off but could not find and jet to clean.

Can anyone advise where to find this jet to clean?

There is no removable idle speed jet on this carb, Remove the limit cap #1 carefully then close the adjuster #2 until lightly seated counting the number of turns it takes. Now remove it completely and shoot carb & choke cleaner with the little straw through this port, Spray it good then re-install the adjuster until lightly seated then open back up the number of turns counted before.

The engine should idle as normal now, If not open (screw out) this adjuster a little at a time and see if it doesn't idle properly.


Good Luck

RestroRob you are the man. I was going to tell him to really tear the carb apart but you beat me to it with better info, pics and all.

Where do you get those breakdowns, I would like to have them available when I tear things apart

Oh....Those pretty pics ?

I get them from all over the net, I've got two computers and two host sites full.

Thanks for the diagram of the carb.

How do I "carefully" remove the limit cap?

Do I pull up on it with a pair of pliers?

Thanks for your help.

I usually pull them off with a pair of needle nose pliars, sometimes a flat blade screwdriver will work too. I don't put them back on though. Just me though.

Mudder has the right idea, But be very careful so you don't snap the end off of it.
