i have a 85 merc 115 inline that loses spark to 1,3,5 off idle. It has spark on all 6 untill i touch the throttle then it bogs and drops the odd cylinders. I have been troubleshooting for about a week now with still no fix. Compression is 145-150 on all cylinders, changed switchboxes, tested all...
just bought a 1971 johnson 50, at least i think its a 71. Need to know the proper mixture. the former owner said he ran 35 to 1. the model # is 50esl71es. serial# e3477419.
