Just finished about 2 hrs. of work in the foothills of Larkspur, CO, and my new PT425 (7 hrs.) is sputtering and stalling.
Before purchasing, I was told by a Kohler shop (as part of figuring out whether to buy a PT) that I would probably have to install a 'high-altitude' main jet. The reason I did NOT do this immediately, is that at 6800 feet, it seemed to run fine.
The engine is the Command Pro 25 HP.
Before I purchased the machine, I talked with the folks in Tazewell, and they assured me that they would make no change in the jetting.
This is not particularly a PT problem, as I've discovered that ALL brands of carbureted engines usually need rejetted above 5000 feet. I'm at 7500 feet.
Seems that ALL manufacturers say this is necessary, but it is NEVER a warranty item.
The really irritating thing is that I have limited options after spending $12K for a new tractor.
I have no way to easily move it, and no shop in the area will come out for any amount of $$$. If I remove the carb and take it to them, they will 'graciously' install the jet for about $40. /forums/images/graemlins/mad.gif /forums/images/graemlins/mad.gif
One mechanic said that changing the jet is really difficult, another said it's easy, but no one seems to know anything about the engine even after giving them the family #, serial no., spec. no., carb number, and my date of birth and checking account balance./forums/images/graemlins/grin.gif
Anyone else have similar issues with Kohler or other small engines? I'll probably end up pulling the carburetor or attempting to change the jet in place.
The new part is under $12, but this is a LOT of aggravation and time for new equipment. I suppose I could just buy a case of spark plugs to change every few days. /forums/images/graemlins/confused.gif
Thanks!
