Bought a vw t2

Hi there bought a t2 and we’ll think I have broken it it was running grand then the monkey (me) changed oil spark plugs sorted fuel leak and air leak now will idle after heated up but if you touch excellerator then won’t idle have to constantly feather throttle, any ideas welcome

I see no one has has come up with any ideas as to your problem. without actually seeing whats going on , I can only suggest that when you sorted fuel leak you may have let in crap in the system and blocked a jet. assuming that you did sort out the air leak. As your post was 3 weeks ago you may have it sorted by now. give us an update.
