Thanks to the replies to my carb question earlier. Following on,my local machine shop had a new weber 34ICH on the shelf,though it's jetted for a 2litre vw LT van,but i took a chance and bought it. Vast improvement over the old carb but a little rich at the top end, so i dropped the 165main jet down to 150,now seems about right but wondered if anyone else is running a 34ICH and knows what size main jet and air corrector jet they are using? Thanks.
