trouble cold starting

[MakO17 90 EvinrudE]

i have a 1997 evinrude 60 degree looper v4 90 hp. when its time to start my engine and it hasnt been ran in a few days, i have trouble starting her.. the only trick i have learned for dealing with this issue, is i take the engine cover off and locate the linkage that connects both sides of the carb butterflys. I manualy give that some play while my buddy starts the key at my command. it takes a few goes of playing with that lever and also the timing lever at the same timewhile the engine is bein started. after a few goes she starts right up, while i am manually slightly holding the butterflys open keeping the motor running i tell my buddy to put the motor into neutral with a bit of gas so she stays running, at this point the engine will warm up and i can slowly bring her back down to neutral. this has seemed to help me however, i would love to figure out the root of the problem becasue my engine never did this before. after a bit of running up and down the intercoastal i can leave the motor off for a bit and then start it up with one turn of the key. i replaced the o rings and gaskets in my primer solenoid but still nothing.. if anyone could please let me know how to adjust whatever needs to be adjusted... please. thanks alot in advance

Re: trouble cold starting

Have you cleaned the carbs and also made sure the primer is working?

yes carbs are cleaned out completely as well asjets.. and i did not take out floats so im pretty sure that its not a ailing float. i can here the primer solenoid sounds like its engaging when i push in the key, it clicks.

Re: trouble cold starting

Your motor has a quick start system, it aids in cold starts and it may not be working correctly. I don't know how to trouble shoot quick start though, so if someone else doesn't check this thread and give you the procedure, do a search on it here, there should be some good reading on the subject.

Re: trouble cold starting

I don't see how you can clean carbs without removing the float and installing the new hi-speed jet needle that comes with the carb kit. The tip of the needle takes a set when its worn.

It sounds like a link and sync is needed if you have to manually play with the butterfly's.

Take a look on ebay for the factory service book, not seloc or clymer.
Searayman usually has them in stock(Ebay).

Re: trouble cold starting

One other thing to check on the fuel primer side is the primer ports that actually deliver the fuel. I had to replace one of mine and that made all the diference. everything can be working fine, keyswitch, primer solenoid, hoses but if fuel cannot pass to the cylinder it's not doing the job.

I also think if you're playing with the butterfies and timer arm it's time for a link sync. There's a special tool required to set the timing on that engine, though there are other ways to do so I found the tool very simple to build and use. I don't have the instruction file handy but can dig it up if it will help you, just pm me.

yes when i opened my carbs to investigate i did not find a any signs of gunk what so ever i took out the orphices and they were all clean i sprayed the float seat with carb cleaner just to be safe. all floats seemed to be working fine. but thank you for the advice i will look into the manual and link and sync.

Re: trouble cold starting

so yesterday i went to start my boat on the side of the house with the ear muffs on, only this time i took a different approach and it started up extremely fast. maybe this information can help some one help me. instead of first priming he ball until it became hard hard, i gave the motor a couple of turns prior to pumping the fuel ball hard, after about 3 small turns of no starting i then pumped the ball until just before becoming firm and gave the key a push foward to engage the primer solenoid and then i turned the key, it started surprisingly on one turn. so in other words i first dry-carb turned her over a few times kind of letting it know im going to be starting it.. then i just pump the primer bulb a bit without letting it get too hard and then i start it. im confused.. why is it happenening like this... thanks for the help guys
