Ok so I pulled the AFM apart this afternoon to check it out and it seemed the gate was pretty well jammed shut! SO, I cleaned it out and hastily put it all back together thinking I've gone done solved it. Should've known better though not to rush putting things back together because you tend to forget things, like for example putting the electric harness back on lol. I started it up, and lo and behold it ran exactly the same with lots of smoke but then stalled due to starving the motor of oxygen. Realising my stupidity I put the harness back on... thinking it should be all good but now there's nothing... not even a little bit of kick :(
Guess I need to reset the computer, to stop it from thinking that something is still wrong?
Changed the fuel filter this morning, but now the fuel pump is making a few funny noises, don't recall it doing this before and there did seem to be plenty of fuel coming through but it might be low now and struggling to get a prime... However it did start before so has got me wondering. Oh well. Cleaned up the spark plugs now and guess will just have to hope for the best tomorrow with a fresh tank of fuel and reset computer.
God I'm an idiot lol.
Thanks guys for all your help, hopefully it'll be back on the road very soon!
