Engine stalling

[Weeb]

I have a 2017 ar240 that both engines stall after the first cold start and then are fine. I have @Mainah push button start but it does it with the buttons or the keys. Today I tested it in my garage at 70 degrees and it did the same thing on a cold start so it’s not outside temps. The port engine stalled a second time then was fine. Any ideas before I talk to the dealer.

Spark plugs are a common issue with the MR-1 engines. I would start there. Also check the air filters for dirt or oil contamination.

To clarify- both engines will start but "stall" and will immediately restart and then remain running.

Is that correct?
Once they do start, and remain running, how well do they idle/run? Is it rough or smooth once started on that second attempt?

 

[Weeb]

Do I have mr-1’s in a 2017?

 

[Weeb]

They smooth out after a couple seconds. Yes they both start and stall. They idle normal after starting.

no M R 1 engines in a 2017 you have the 1800 engines

First step, Spark Plugs.

 

[Bennie]

How many hours do you have on your engines?

 

[Weeb]

I think there is around 60 hrs and on the original plugs.

 

[Weeb]

I have new plugs I’ll start with them.

 

[Weeb]

It’s just weird that it would be both engines starting this issue at the same time.

 

[Bennie]

I agree. What's the voltage on your batteries?

 

[Weeb]

12.4 on the start 12.3 house.

 

[Weeb]

They start and run fine for about 5 seconds before shutting down.

 

[Bennie]

Brother at 60hrs I would definitely start with the spark plugs.
It does seem weird that both engines are being effected at the same time with a wear item but either way its still something that should be addressed/replaced. Perhaps someone with more experience on engine problems like this will be able to chime in. (knock on wood)

 

[Mainah]

I am with everyone else in that both engines at the same time is wierd. No idea what would cause both at the same time.

 

[Weeb]

Since I only have one chance to test things a day I think I’m going to disconnect the push start first just to rule it out before I start replacing things.

 

[Bennie]

Do the engine's "sputter" out or just die, as if electrically killed. (Ie- faulty switch)

If its cold start only, could fuel be losing prime.
Do you wait till the connext comes up and the tachs finish their sweep?

 

[Weeb]

Yes the keys are always on for a bit before I start it and the connext is up. I went into the system check area but couldn’t see where to check codes.
