Asthmatic PX

[RWS74]

Px150 2014
Sip 2

ZEUS CDI
Oil change Saturday & new .6 gap plug two weeks ago.

Evening all, my PX150 started making a strange sound when starting from cold the last few days.

It sounds like an asthmatic cough on the last compression if it fails to start straight away.

After that it starts fine and runs tip top.... I also noticed the kick start has been harder to start engine from cold too which is unusual as usually 1st time, the only thing of note is I tightened the clutch cable to spec 2mm or so on Saturday but I can't see how that could effect it?

Any ideas folks or have my hearing Aids suddenly improved and I now hear a normal failed start?

Ta Muchly,

1st check , make sure your plug is in right ,the sealing washers can settle on new plugs ,undo, clean the part of head it seals on ,in finger tight then 1/8th to 1/4 turn to tight . H

Apologies for delay replying Henri, I checked plug and refitted and asthma continued... I thus replaced plug and no more asthma...
