Nikki twin barrel carb jets

[bertsmobile1]

Doing a 2008 Sentinel with a 406777 B & S that I have never touched before
Spasmodically drops one cylinder .
Could not find any obvious problem.
Ran the tiny tach on each side got close enough to the same RPM to rule out a maggy problem
Cleaned the carb so that should be fine & it was too clean not to have had some one else in there before .
Did the valve lashes , were pretty good in the first case
However still drops one side.
Now one plug is rich & the other is quite lean
Would I be right in suspecting some clutz has transposed the jets L to R.
I did try to read the jet numbers but they had been damaged and the old eyes + the biggest coke bottle can't get the stampings big enough for me to read.
Plug photo below.
L is left plug lean burn & right is right plug rich burn.
Checked around and no one has jets in stock at the moment & I really don't want it here for a month while I wait for jets from the USA.

I am pretty sure the bigger jet goes on the left cylinder. The ones i have worked on were 114 and 111 jets.

Thanks
That bit is in the manual
I will bit the bullet and try swapping them when I finish doing the Z225 I just started.
Penny should have dropped before put the moungrel thing back together
Hate pulling these carbs off
BTW looked like 118 stamped into the justs but they were scratched up really badly so very hard to read
