1975 135HP ESL Won't open up

[jbailey07]

I have a 75 model 135 ESL that starts and runs but will not open all the way. Choke motor and no change. New plugs installed and fuel pump. Carbs have been cleaned out but not rebuilt. I've been told the stator is bad.....Where to begin and what to be looking for. Been a mechanic a long time just not familiar with boat motors. Anyone wise enough to help can email me

Mod EDIT: email address removed. Jbailey, although email addresses are now permitted to be used as user names or posted in the open forum, we dont recommend putting it on an open forum, where anyone trolling for data to mine, could find it. Instead, in this instance, I removed your email address because this forum is a resource, open for any and all to use. If all the help repairing all the various motors posted on iboats becomes an email discussion amongst just 2 or 3 members, the resource and those that follow us loose. Same for having private message dialogs in pursuit of a solution. So, lets keep the discussion in the open forum.
Thanks
Best of luck getting your OB running right​

Compression test? spark on all cylinders??

After you do, item #2 above: When you cleaned the carbs, you need to pull all the jets out for a visual inspection to be sure they are not clogged with debris. Can't really clean them without a teardown. Clean with an aerosol product like GUMOUT. Are the carb butterflys opening all the way at WOT? You need to pull the airbox cover to visually check. Are those butterflys in each carb in sync with each other? Timer base moving?-is the link arm connected between it and the spark advance lever. When you choke the engine, that provides extra fuel. Normally, the engine should slow down-as it is being overfueled. )(Or the choke is not functioning.) What is the max rpm the engine will currently run?
