Stihl MS 500i Cutting after troubleshooting

[@DeliveryBryan]

I own a 500i myself . And when I start my day of firewood cutting I let it idle for a little bit while I'm grabbing my stuff out of my truck . Once I get PPE on , my wedge banger , wedges . Then I shut the saw off . Then I go back and start it up again . Got it ported and runs a 28 up to a 32 inch bar !

We run the snot out of 500i on the fire line. So far not impressed with em. Trouble starting when hot anything above 95° out and our two 500i saws were overheating. Struggled to start up after fueling. And at one point my saw seemed like it was in limp mode, limiting itself in the cut while dropping a snag. The 461s we had out that day, didn't have any trouble overheating or starting while hot. They ran well for one season and now this season I'm hesitant to take em out on the fire line.

Own one of these and I like it for ease of starting. Still love my old Macs. They will out cut this saw but temperamental.

Sweet runner sir!!

I have a new 500i. It cuts great but is a bitch to restart after being shut off for a few minutes. What is the problem? Any ideas?

[@northwestperformancesaws6212]

Sounds like the injector is partially sticking open after you shut it off. How long are you waiting between shutting off and restarting? A pressure/vacuum tester can test for this without too much effort. If you don't have a tester like this then I would take it to the hands of a decent tech to run the test.

Was the replacement of injector module a simple remove and replace? Or was there some calibration required to get the module to work properly?

[@northwestperformancesaws6212]

It actually was a pretty simple swap. After swapping modules the system adjusted and ran without skipping a beat. There are 4 screws that bolt the entire injector housing to the cylinder and two really small metric size 3 screws that secure the injector itself to the housing. Just have to go slow and easy when dealing with the wiring harness and the plastic shroud that goes around the top of the housing and spark plug. I went slowly when getting that plastic shroud off, constantly felt like I was going to break it.

@@northwestperformancesaws6212 Thanks. It is pretty much what I thought, that the Stihl was a solid machine and wouldn't require specialized equipment to fix something like a faulty injector module.

@@canamrider7195 Yes indeed a lot simpler than one would think.

[@northwestperformancesaws6212]

@@canamrider7195 I should actually backtrack a little. In certain cases you are supposed to hookup the saw to the MDG1 analyzer and SDS to re-calibrate the saw. Stihl says that you're suppose to do it when replacing major engine components, fuel system parts or ignition components. This being said I would probably do the re-calibration if I had to replace major engine components or the ignition parts under the flywheel but otherwise I don't feel that its absolutely necessary to make it run right. Others may chime in that feel differently and that's ok. Personally i'd rather share all knowledge possible when it comes to the new 500i's.
