Before the great crash of 2011 I was posting about some issues with my engine, backfiring and popping on deceleration as well as poor tickover and a slight oil leak. Well it got a lot worse on the way back from Whitenoise with a load of smoke coming out of the right hand side on acceleration and a much worse loss of oil. Well thanks to some help from you guys I was able to determine that it was as you suggested a leak in the vacuum from the carb to the brake servo. Now this was a real pig to find as the rubber had spilt behind the canvas cover so now that it is replaced it runs like a top. The leak was coming from the dipstick tube and I have sourced a silicone high temp replacement for the small rubber tube that was there so that should be me all cured. I know Zed replied to my original tale of woe as well as somebody else so if you let me know who you were I will send some Karma your way.
