i have a 84 invader with the aq 125 b 4cyl volvo /270 out drive. i have an intermittent starting problem i need advise on. i originally thought it was the neutral safety switch as it would not turn over. i would have to put the gear selector in neutral and pull the lever all the way towards reverse then the starter would engage. before that no click no anything. i then bypassed the neutral safety switch and had the same thing happen again. again, put the lever in neutral and pulled it all the way back and it starts at full throttle though. is there a switch on the trans linkage or some other lock out mech? thanks kc
