iv just put a new engine in a 3ddi 951 model conected everything up but broke a nipple off the rave valve solenoid fitted new battery plug lanyard on normal 2 beebs but when cranking i get one long beep it is trying to start would that air line be the problem or should it still start as its only meant to open raves at higher rpms ive got fuel and spark im just wondering if that lack of air pressure is the problem
