I have a 1987 90 HP Merc. I have new carb kits and am getting ready to pull the carbs for cleaning and rebuild. I was looking at the linkage that connects the 3 carbs together, it's a square plastic bar with plastic clips.

How do I get the linkage off the throttle arms without breaking the plastic clips and disturbing the adjustments on the linkage? I have a Seloc repair manual and can't find where it covers this part of removing the carbs. I want to do this right without messing something up.

The engine was tuned up by a Merc Mechanic and timed and linked and synced the last season the previous owner ran it, about 2 years ago. I don't think the carbs have ever been off the engine, if they have it's been a long time. Is it possible to rebuild the carbs and just get by with adjusting the idle screws and not doing a link & sync again?

The reason I want to clean the carburetors is because it's been 2 years since it was last ran and they have been using gasohol.

I'm also planning on replacing all the fuel and oil lines while I'm in the process. The oil lines look like they might be a clear plastic tubing. Where can I purchase the correct tubing for the oil lines?

Re: Rebuilding Carbs-Need Linkage Advice

Noticed you are looking for new oil/fuel lines. you need to pay attention to the inside diameter. I bought new fuel lines at the auto parts store, maybe you can get oil lines there to, is it nesseccary to have clear lines? If not maybe an auto parts store can help. Dont know about disconnecting the linkage though. Might want to think about taking several photos before you disconnect everything, if you have a digital camera. would help in putting it back together.

The linkage should just pop off the carbs with a little care, sometimes a screwdriver or small needle nose pliers may help pop in them off the balls on the carb levers.
