Hello,

just thought id drop in a quick note too say i had exactly the same problem with my S1 after a rebuild and it drove me nuts !

In the end it fired up for me ..from memory i spent alot of time loosing banjos ( to try and bleed out any air ) and getting a mate to press the flap down etc. Don't give up ..although it is annoying.

Few things to consider that MAY help..

- Make sure all the vacuum pipes are on and tight..i've learnt that the MFI system HATES leaks

- Take the plugs out and spin it over just in case the engine is flooded

Good news is once it starts it should be fine ive left mine for a while now so im hoping itll be ok lol

let me us know how you get on ?

Good luck , pete
