Hi all.
Have got an LPG system in my Doka. Was already fitted when I got it so know very little about it really.
Used to work fine. I had to remove engine but now its all back together the LPG has a cliche.
Keeps switching back to petrol when the revs drop. It stays on LPG while revs are up but when I change gear it switches back to petrol. If I rev it, it goes back to gas until revs drop again.
Tank is full.
Where should I start looking?
