Greenmech starting issue

[Shaunpaul]

Hi, anyone any ideas why chipper starts from cold but sometimes struggles once warm to start up again?  But then leave for 10 mins and starts first turn again 🤔. Changed plug and all filters but no joy. It’s a 150 petrol 2019 just over 450 hours.

thanks

Can you hear the high pressure fuel pump when you turn the ignition on ?

When was it last serviced  ?

Have the tappets ever been adjusted  ?

Jase.

[Jase hutch]

Sorry I can see its been serviced. 

Was the in line fuel filter changed  ?

[Shaunpaul]

Hi Jase, yes in-line filter changed

Is the fuel filter in the correct direction.

 

Probably not a bad thing to disconnect the output side of the filter and ensure that the electric fuel pump isn't blocked or getting a bit tired.

No expert but in these hot days, has anyone experienced something like a fuel evaporation symptoms? EFI should start pretty well straight away sois fuel evaporation in the system causing this? Unlikely as the high pressure fuel pump should be squirting at 32psi which should instantly bleed any dry sections....

Not familiar with that system, but one client's lawnmower has been known to actually stop in very hot weather, and is an absolute swine to restart if you've foolishly stopped it hot on a hot day.

You all forgotten my Efi saga then? 

It started the same way...
