I have read many posts from you and always thought your input was accurate and based on sound judgement even to a total novice such as myself. I will check the 2 boots as you suggest-they are quite difficult to follow and access as well as being rock- hard. I have changed the ICV recently so it would make sense I have perhaps damaged the hoses/boots. I did seem to have a very lean mix before my no-start. Thanks for the advice!!
