So finally got the Doka out and taxed and took it for a run to get more fuel and it was terrible. Kept cutting out and I had to feather the clutch to keep the revs up and very little power on acceleration. At first I thought its bad fuel so filled up with 30L of E5 and I thought it would sort itself on the run home but its still terrible. Over winter I took it out from time to time and turned it over but didn't take it for a run.
I have checked the leads, plugs, timing, dizzy cap & arm, fuel coming from mechanical pump, fuel filter and carb witches hat filter and all are good.
So I had a bit of a look at the carb, this is the choke at cold with pedal pressed once...which looked quite open compared to what I have read on here.
I gave it a bit of a clean up with the airline and lubricated the choke mechanism and adjusted the choke gap. As you can see someone has made their own replacement part with yellow plastic, once I got to this stage I realised the carb needs a complete rebuild, the old girl is 37 years of age and I am sure many parts are worn. I popped it back on and it is running a little better but its not wonderful.
I had a long chat with John from BromyardVW and a recon unit will be in the post in a couple of weeks
