Hi all,
I'm hoping for some help. I've viewed this forum for a half year or so and tried some to the things I've seen posted here on my motor. So I have a 1991 evinrude spl 40 on a Lowe 1700 deep V. I got the boat last year from a guy who was getting rid of it because he couldn't get the motor running. He said the guy he got it from had it running the previous year. Anyhow since I've had it I had trouble getting it to start, idle, run! I have rebuilt the carbs, installed a new fuel pump/filter, checked compression, replaced ALL fuel lines from the tank back. The fuel tank did have a good bit of water in it so I have pumped that out and I've hooked up a transportable 3 gallon tank that i use on my jon boat.
My problem is completely inconsistant. Sometimes i can get it to run for a few mins but when i turn it off it wont start back up, typically it will not idle, i think i was getting some back fire when i had it at higher RPMs (assuming a timing issue). I haven't touched it since this past fall (2013). As soon as the weather in Maryland breaks im going to get it out of the barn and give it a go again. I'm looking for some tips if you guys can help me.
I'm planning on replacing the impeller pump first thing because it seems to take longer than expected to start pumping water out (roughly 60 second?) I'm also going to soak the carbs overnight and use wires on the jets to clear them just to be sure. I'll report back as soon as i try these things. Any other help would be greatly appreciated.
What else should I try???
