86 150 will start with just a bit of starter fluid help; doesn't take much. Engine running good after starting. Looking to track down start issue. Upon running, I can key the primer solenoid, hear the click, but no change occurs in engine performance. I would have thought the engine would bog a bit anytime I pushed in the key. Is this a potential sign of a primer solenoid that needs rebuilt/replaced? Thanks

Test it:
1 - Find one of the small hoses that leads from the primer solenoid to the carburetors or intake manifold and unplug it.
2 - Pump the fuel primer bulb up hard.
3 - With the key turned to ON (engine not running), push the key in. When you hear that click, you should see fuel shoot out the end of that hose.
With the engine running, pushing the key in and holding it there... that should have flooded the engine out. -
I checked the line going from primer to top of the top carb and fuel is flowing. Is it worth it to pull the carbs off to get to the other lines for the bottom two carbs? It doesn't seem the primer is the start issue.
I am into the 2nd hour of the break in procedures and all other indications seem ok, with the exception of the cold start issue.Comment

I feel sure that you are well aware of the proper starting procedure... fuel bulb hard, slight bit of throttle applied, key turned to START and key pushed in and held until engine fires/starts, then release key.
The fuel primer solenoid is functioning properly.
The fact that you state that when running, you push the key in and the engine doesn't change rpms leads me to believe that...........
The gaskets between the carburetors and the intake manifold are the old type gaskets designed for the older electric choke models and do not have the necessary hole in them to allow the primer solenoid fuel to flow through the gasket into the reed plate/leaf valve areas.Comment

Joe, you've been very helpful. I appreciate it greatly. In terms of checking the gaskets between carbs and intake; if that is the cause, can holes be punched into the gasket material, or would I need to source a gasket with the right holes?
ThanksComment

The only difference between the gaskets is that access hole. I strongly suspect that you are well capable of doing that modification... it doesn't have to be perfect.Originally posted by 86Dynatrak View PostComment

So........ Did that cure your problem?Comment

Joe - finally got around to working on it again. Sure enough, the gaskets did not have the primer fuel hole punched out. Unbelievable. Once I replaced, she fired right up and has been running excellent thru the break in process. You're the man Joe!Comment

Thank you my friend, I really do appreciate that compliment. Glad to hear that your problem was a small one... happy boating. (Joe)Originally posted by 86Dynatrak View PostComment
