I have an A3 that ran great on the original Encarwi carb and factory intake. Started on the first kick. Bought the new intake from Treats that lets me run a Dellorto and now it won’t start. Bought the genuine Dellorto carb from them at the same time. The carb also included the correct bushing for the carb. Spark plug is almost new and sparks well when I ground it to the engine. Notice if I remove the carb and put my hand on the intake while kicking, air seems to be sucking in and blowing out. Compression shows just over 100 psi. Any ideas?
