Hard to start Evinrude

[dfrants]

don't you need different carbs to use a primer?

Sure sounds like the choke isn't closing all the way or staying closed when you crank it.

You can mod the old ones. I did.

Should be an easy retrofit.----Installed these units on inline 6 Mercury motor .----Then no more hard to start problems.

I'm not going to be much help here but I had an 85 HP motor just like yours that acted the same way. I tried about everything from carb rebuilds, spark plugs, fuel pump etc. and never got it off of the starting fluid. I'm pretty sure I tried the manual choke also. It would start the rest of the day after I used starting fluid the first time. The lower unit finally went out on it so I replaced it with a 140 of the same vintage. If I ever try to do anything with this motor I'm going to look into the electric primers as mentioned. How do you install these primers? Where are they wired into?

Step # 1 would be to learn how the primer works.----And instead of the single wire going to a mechanical linkage choke solenoid , the wire goes to the electric primer valve.----No wiring modification needed.---The fuel line from pump to carburetors needs a T to supply fuel pressure to the solenoid.--And the wee fuel lines from the primer need to have a place to spray fuel into the engine.----Originally done at the bypass covers and later at a nipple installed on the carburetors.----Fairly simple in my opinion.

Have to note that whatever you do, the primer nipples have tiny tiny holes. About 0.020".

 

[racerone]

Actually they are smaller than that.

Special "thanks" to all you guys for your input!!! It did turn out to be a choke plates not staying completely closed with the key pushed in. From the steering wheel it looked good, but when I went back to the motor and physically touched the plates I could feel a slight gap. And that's all it took. Thanks again guys!!!

As per post # 3 on this saga I suppose ?
