primer ball
 

1980's vintage 60 hp merc outboard 3 cyld all at 125 psi
dual cars clean no leaks an fully synched.
primer ball won;t go hard,new primer ball won't go hard ,changed fittings
at both ends of gas line still won't go hard. motor is a little hard to star
but does star and run very well most of the time except for the odd time
when at full speed it will stumble as if fuel starved for about 2 sec.
might be in my mind but seems like perhaps top end is down just a little .
Any ideas ?
thanks

In Canada, they might say that your primer ball is "full of
shi..",wait, sorry, that was another thread. Joe probably won't be
responding, though.

Look for an air leak at the fuel line/engine connection.

3 possibles......
Fuel Leak outside - you'd smell it. Not likely.

Fuel Leak Inside - ripped diaphram in pulse fuel pump. You're pumping
fuel into one cylinder's crankcase raw with the bulb. As the rip is
open, it'll never get hard.

Stuck float valve....pumping gas up into the carb and into the gullet
of it.....never closes.

As it acts fuel starved, I'm for #2, fuel pump diaphram blew a hole in
it that time it backfired, remember?

My 7.5hp merc acted like that and it ended up being a airleak where the
fuel line connected to,the engine. You might try when it is acting up
pumping the primer bulb to see if stops the "starved symdrome" could be
anywhere in the line. (or I could be wrong)
