ISV or dodgy fuel...

Cleaning them is not a great solution. And usually only last for a bit as they are still full of gunk and crap.

Get yourself a new one mate...

I just sold the last one other wise i'd offer you one

Cheers.

looks like I may have to....
is it a standard item?...or is there an upgraded version..
as I plan a power increase over the next few months....

cleaned once a year with carb cleaner for the last 8yrs and its the original and still going strong.....struggling to see any issue so far

no doubt just jinxed that then

The only reason I said that is there are so many different ones on the market some more aggressive than others WD40 is just a safe option.

Whatever works works

No problem cleaning them out rather than buying one new, with all the PCV gunk that goes through the system it's no surprise really.
