Midway through the engine swap now and the 1.1 motor we have transplanted has the 28if carb so we thought we might swap the 32if off the original engine. Will we need a r5 manifold/rocker/waterpump or can we drop it on and use the hot air feed to reduce carb icing, will it even fit the manifold or do we need the r5 carb? Photos to follow.
