73 88hsp Evinrude

It will not start without starting spray. Once its warmed up it runs fine and will restart with a touch of the key, will idle fine. If it sits for a a while its really difficult to start.

Is the choke system working properly?

Re: 73 88hsp Evinrude

Great question. That engine's a bear to start (when cold) if the choke is not functioning properly.

Re: 73 88hsp Evinrude

Yes this model has an electric choke which is disconnected. But does have a manual choke on the front of the motor and I use it. I had a 140 that was a 76 and was a pain when cold also. But this one is really hard. Like its not getting any fuel when it sits for a while.

Does the primer bulb pump up firm?
Are you lifting up on the warm up lever when cold starting the engine?
Can you post a model number?

Re: 73 88hsp Evinrude

Any reason why it's disconnected? Does he choke solenoid work? If not, why not get a new one and connect it up? That engine should have a dual stage choke which stays partially closed till the engine warms up, based on the special sensor in the top of the block.

Re: 73 88hsp Evinrude

I was given the motor so I don't have much history on it. The electric choke is discoed but this is Florida. The water right now is still 80. I understand the advantage of a partial choke till it warms up be we have to get it started first. The manual is working and the bulb is tight. This motor just might be tired.

It's always good for a new owner to get an idea of what the compression is on a new engine. Have you tried to check the compression while cranking it over? I would think this engine would normally be in the 120 range.

Re: 73 88hsp Evinrude

Actually, the water temp doesn't mater much for a cold start. The reason for a choke is to supply extra fuel to get the engine started, if the engine temp is not up to normal temp, the low speed circuts in the carb doesn't supply enough fuel to start the engine.

Re: 73 88hsp Evinrude

I understand that the water temp doesn't matter. Responding to the gentleman that let me know that the electric choke would stay partially closed until warmed up. Down here that doesn't mean much. Also I understand how a choke works and that under cold conditions the idle "fuel circuit" in the carbs won't give enough fuel. I understand it may need a compression check. What I was asking if there is some PARTICULAR quirk to this model what would cause what is happening.

Re: 73 88hsp Evinrude

Probably a redundant question, but I'll ask anyway. You said you use the manual choke on the front of the engine. So you've visually (remove the airbox cover) checked to see that the linkage on the choke actually closes the choke butterflys on the front of the carbs?

i like seafoam for all 2 strokes.

Kahuna, You've replied numerous times(530 to be exact) in these forums. I'm sure that you know your way around an outboard. What are your compression #'S? Have you been thru the carbs yet? Couldn't hurt. At least that way you know the carbs are spotless.

Re: 73 88hsp Evinrude

Yes and no. I owned a marine electronics and electrician business for years. Mostly I worked on larger boats. Rewired a few from scratch. One is still making money in Jamaica after 20 years. But to the point, down here we don't have older outboards, salts too much on them. You guys in fresh cold water get more "acquainted" with older models so I turn to you guys for help. Same reason you don't see I/O's down here for very long. I am learned quite a bit from this forum.

Sea foam has really helped this thing out. It will now idle much better and seems almost trustworthy for a ride. It just won't start cold without help.
