You may have a bigger problem - is it a legit Weber carb? If it's a 'licensed copy' (read as 'bad knock-off) you will never get this thing to run right. Tips on installing a Weber carb - used a high volume, low pressure electric pump (don't try to regulate the mechanical factory pump as it will eventually kill it) and ensure it's a genuine unit. Plug the coolant port under the carb to eliminate possible coolant bypass issues as well.
