heres what we have done...
checked cylinders for compression with a good guage...
all have a fair amount of compression, except no#2
now... the engine turns over fine/smooth/ and cams operate fine/smooth
how ever when turning over checking compression, there is no fuel comming out of the cyclinders??????
maybe this is why it wont fire or run? even if the compression was down it should still fire and idle, but it wont at all, ignition has been checked and all are sparking fine.
I can only put it down to no fuel?
A mechanic I have been talking to has suggested that its more likely that the fuel is the issue and the compression in No#2 was probably always an issue, and could be caused by burnt valve/seats, which can be fixed by taking the head off and grind/polish/shining the valves and seats.
Given that I was not giving it much and the main reason it stopped was the throttle comming off, it would be very wierd for the piston to ping (run lean), how ever there is a fuel issue here but I susspect at this point that it is why the engine wont fire or run at all, I dont want to pull the engine out replace the pistons and find it still wont run..
