TerryF Posted February 2, 2002 Share Posted February 2, 2002 Last week I reported that my crossflow was revving at about 4000rpm on ‘idle’ following a routine service and oil change. The revs dropped of their own accord but the idling was very lumpy. The electrics were all good so I checked the carbs (DCOE 40’s), I took off the K&N filters and removed the stainless steel venturi. I then removed the inner alloy liners from within the inlet passage to find that the centre tube within the liners had completely melted! This was on 3 & 4 cylinders, 1& 2 being OK. There is no other apparent damage to the carb, but there has clearly been some form of blow back or other local overheating. The liners can be replaced, but does anyone know what would cause this problem and why? TerryF TerryF Link to comment Share on other sites More sharing options...
Paul McKenzie Posted February 2, 2002 Share Posted February 2, 2002 You've had a fire (I guess that's obvious) inside the chokes - I've seen the same thing twice before on crossflows, although I don't know if it's engine specific. Some cross-flow and Weber experts will be along in aminute to tell you why it happened. Paul Link to comment Share on other sites More sharing options...
