Hi guys, wondering if you can help me.
My carb has both needles vertically orientated above each other, and I have no idea which is the high end and the low end.
cheers.

Mike,


On the body of your Walbro carburettor, next to each needle, there is a letter.
'H' signifies 'high'.
'L' signifies 'low'.

The upper needle is the 'high' and the lower needle (nearer to the base of the carburettor) is the 'low'.

If that were so Dar, I wouldnt need to know which one was which!
But thanks for the info Dar.

Look at this drawing:

Log into http://www.mvvs.nl
Go to 'Petrol' on the left and scroll down to the carburettor adjustment instructions hyperlink.

Click and look.

PS,
That is the very sparse MVVS leaflet. Better visit my forum, where I explain the carb in detail using the original Walbro documentation.
The needle closest to the engine is the idle, the upstream needle is the high speed.

thanks Pe. I had found that thread and read it thoroughly. The needle identification eluded me throughout though!
Thanks for clearing that up guys.

I updated the forum publication. Oftentimes you tend to forget how difficult all beginnings were.
