Efi Vanguard poor starting.

Could this be the fuel pump again?

I changed the fuel filter, the air filter is clean and the fuel pump was replaced under warranty a few months back.

If I throttle up however slowly, sometimes it does not respond and I must let it chatter away a while before throttling up again.

Not looking forward to leaving it with a French dealer for warranty work.

Last time it was away a month which cost me €2400 in hire, 900kms travel all for a €150 part which takes 20min to fit.

 Looks like a call to Briggs Bits...

I’ve got the same engine but in a forst and it just started to do something similar but when I rev it up will splutter like a chockage but everything has been changed even the spark plugs twice. Can’t understand it

Ring the factory for advice. You do have the numbers.....

That sounds like a skeleton having a wank in a biscuit tin! ?

 

if It is only doing it cold it could be worth a compression test to rule out wear in the rings/valves.

This evening I've emailed the sales director asking for GM to send a transport to come and collect it and attached a few videos.
