Hey folks, My bus has started playing up a bit lately so just looking for some advice on what it might be. It is idling very fast, has terrible run on and the plugs hot which has led me to assume it is an air leak somewhere. It first started around when I did the timing a week or so ago, so I re did the timing a few days later which made it a bit better but then it came back after a few days of driving. Today is the first day I have had the chance to have a decent look at it. The vacuum lines dont seem too bad from what I have checked. So far I have checked the elbows inside the engine bay, the brake booster line going out & dizzy vac line. I havnt gone as far as the brake booster, although had a look at it and couldnt see any obvious places where it might be leaking + the booster is working fine. I am now thinking it might be the carbies leaking. One of my carbies seemed pretty flooded when i had a look inside aswell whether it be related or not. I am yet to hit the carbies with wd40 to check for leaks as i ran out of light tonight. Can anyone else shed some light on what it might be or what i should check?
