Tuning a 400cc Hisun 2012 model

Recommended Posts

I recently (like yesterday) bought a secondhand  hisun  400cc 4x4 SxS. It’s a one owner 2012 model only done 125 kms. It runs rough and won’t idle  for long without cutting out., even when it’s warm.  Here’s what I’ve done to try to sort it without success: cleaned air filters, cleaned spark plug, emptied old fuel and replaced, replaced fuel filters. I notice that there is a hose coming from the carburettor (on drivers side). It goes to a T piece but  neither branch connects to anything and I can’t seem to find any places where they would naturally attach.  Any suggestions appreciated.

In the end I bought a cheap Chinese carbi on eBay for $78. Now it runs  perfectly.
