Hello,
I am not familiar either with these more recent engines..however I have a feeling that the smaller spring may be ok.??....whilst the loose end of the larger spring..the elongated loop...may well go into the loop in the link that joins plastic vane to carb spindle. I think this larger spring looks to have been slightly stretched at one point...but whilst not good will not stop a run...
Lets see if this tallies with what gwiz finds on his stock engine.?
The white plastic vane is all part of the constant speed governing of the engine....quite difficult to describe...but basically the 2 springs open up the carb spindle to full revs...the plastic vane is then blown by air from the flywheel fins which closes down the carb spindle to a position where it settles so the revs are constant.
...... but then as the mower is put to work the effort of mowing starts to slow the engine..thus the blow from the flywheel fins decreases and the springs pull open the carb throttle a bit more to maintain engine revs and thus provide the power to mow...
A car engine does not have this constant speed governing...in effect it is provided by your right foot...as if the car engine needs a bit more umpf you press the accelerator a minute fraction more to keep the car moving at the same speed...
I hope you can get the jist of my explanation..... :?
What does concern me slightly is what looks to be some green tape?? that is around the tube where carb meets the inlet pipe...again I'm not familiar with these so lets see again gwiz thoughts on this ref his engine.?..in case I'm mithering for no reason :oops:
I suspect the carb will be fitted to the intake pipe in a similar way to earlier models by means of a push fit over the pipe with an "o" ring within the carb mounting being the seal...If there is a poor fit at this point air will be drawn and operation will be poor/no go.
I second gwiz thoughts ref trying to start minus the blade....most small rotary mower engines with direct drive to blade will not start without a blade..or with a loose blade...this can cause the rope to snatch back as the engine tries to fire back rather than being helped forward by the weight of the blade...and of course any attempts to run with a poorly fitted blade are a definite Bad move.!!
I hope you can get it beat and running again....
take care,
