MK2 wont tick over

[Cadiddy]

Update time, i've tried the wd40 to no avail and have renewed both clamps for the inlet rubbers, neither the mixture screw or the idle screw make any difference at all but the choke makes some difference but the revs eventually run away. Really quite stuck here now

WHere are you in the country .

Hayle in Cornwall

[knackeredMk1]

Too far .

Are you running premix or autolube . What pilot jet do you have

Running out of options ................ next is crank seals ................. then crank cases......

[Cadiddy]

it's running auto lube atm, the pilot jet is standard as far as i know

[Cadiddy]

Will the breathers and overflow pipes have anything to do with it? for example the bore on the replacement hose i've used is small than the original and not exactly the same length

[knackeredMk1]

No. The pipes won't effect this ............ unless they are blocked .

[Cadiddy]

The new one's i fitted definetly werent blocked, would it be worth removing the rubbers and checking they're not punctured or holed?

You're going to have to strip the carb again, and use the manual of this forum to reassemble, from the info given, something has been put back in the wrong place or order.
Float height springs to mind as the principle culprit.

Ok, would the float be too low to be causing this running issue, is the manual in the FAQ section?

[knackeredMk1]

Could be low float height . So the level is falling low enough for the jet to suck air.

[Cadiddy]

I have tried adjusting the height because it was overflowing so maybe it is that i'll try tomorrow

That sounds like the problem, If the bike has been stood then the inlet valve will be gummed up, this was the cause of the excess fuel.IMO, replace the valve, reset the float height.
Generally, a sharp RAP on the side of the float bowl will cure a sticking valve.

[Cadiddy]

ok that sounds a bit promising, would compressed air clear out the valve? I have tried the sharp tap but it was no different

[fallenmikethebike]

Check it when you have the carb apart, but budget for a new one.
Some carb cleaner might clean of old emulsion deposits.
