Hi,<br /> im not as dumb as i make my self out to be but once again im here to ask u people about advice. as u prolly know i have a 85 evinrude 115 vro v-4 , and it will not start. i took the plugs out 1 at a time and laid the on the block and used jumper wire and turned it over to see if there were getting spark and all 4 were, i also sprayed a squirt of gas in the plug hole and tryed to fire and it started to seems to me like back fire but it would never start, is that a bad thing or a good thing. i am going to buy a compression tester and i already replaced to key switch and all i can think it is ,is a faulty wire some where on the motor. yes i have tryed choking it and its a no go.............than....tex :cool:

Re: The saga continues of the non-starting evinrude

If its getting a spark on all 4.. its unlikely to be wiring problems..<br /><br />have you had the flywheel off lately?<br />If so, why? <br /><br />I'd check your carbs if I were you.. take the drains out of the float bowls on each carb.. (a bolt on the lowest point of each carb) and see if what comes out.. if its nothing, then you have a stuck needle or something.. strip and clean the carbs..<br /><br />if its full of dirt and dirty fuel, ,same thing, strip and clean..<br /><br />Check that the butterflyes in the carb are opening and closing the same on all carbs.. (mostly make sure they open and close with the throttle..)<br /><br />Without being there and seeing what you have, we can only make blind suggestions.<br /><br />get an oil can, put 2stroke mix in it, and while you are trying to start it, squirt alittle into the carbs, see if it fires..<br /><br /><br />rgds<br /><br />Frank<br /><br /><br />PS, how old is the fuel you are using?

Instead of spraying fuel into the plug holes, replace the plugs and wires. Then, spray a 3 second burst of WD40 into the carb throat, and try it. If it sputters at all, your problem is fuel delivery.(plugged carb or fuel pump.

Make sure the Wd40 is over 5 years old or it will not work.( it's now nonflammable) What part of Texas do you hail from??

I run up and down east Texas, don't get to Dallas to much. If I did, would take a look at it for you. <br /> Spark + fuel + air = run<br /><br /> fouled plugs don't spark

Yexas,<br /><br />You need four things to make it run.<br /><br />1. Fuel.<br /><br />2. Air.<br /><br />3. Spark at the right time.<br /><br />4. Compression.<br /><br />I think you have #2. Numbers 1 and 3 are debateable. Don't know about #4. I would put my money on #1 as being the "missing link".

Re: The saga continues of the non-starting evinrude

The reason one person asked about the flywheel removal bit (in my opinion) is that the only thing that will make that engine backfire (really backfire) is if the flywheel key is sheared (even slightly). The flywheel nut should be torqued to 105 foot pounds.<br /><br />To check the spark properly, remove all of the spark plugs and set up a spark tester of some kind whereas a gap of 7/16" can be set. The spark should jump that gap with a strong blue flame on all cyls.

Re: The saga continues of the non-starting evinrude

Referring to the 105 ft lbs on a flywheel nut I wonder if most peeps just hammer em on with a 1/2 inch Ingersoll impact like I do. lol. I think the carbs are dirty or fuel aint getting to them. If the flywheel sheared the nut would be real loose or the prop would be chewed or new.

Re: The saga continues of the non-starting evinrude

yeah, that was why I asked... I didn't think that there was much chance he'd know if I asked him if he had checked his keyway...<br /><br />Incidently, even if it has lowish compression, it should still sound like it wants to start,, even if it doesn't. unless the rings are gone entirely or something.<br /><br />My guess is fuel also.<br /><br />So get that can of two stroke mix.. (even with vro I'd use two stroke mix for this..)<br />put it in the oilcan and squirt a shot down the carbies...<br /><br />one of the things I used to do.. is take all the plugs out.. squirt a heap of two stroke into the plug holes.. (I mean lots of it.)<br /><br />then turn the motor over for 30 seconds with the plugs out.. (put it in the water muffs so you don't clag your watar pump impeller)<br /><br />after the 30 seconds.. leave it sittin there for a couple of hours so the fuel can evaporate.. (some oil should stay there though..) then give it another 20 seconds with the plugs out.. <br /><br />then put them back in, give it a little shot of mix down the carbs and try again..<br /><br />don't know why, but that worked for me a few times in the past..<br /><br />It must be like a poor mans partial decarb. :)<br /><br /><br />rgds<br /><br />Frank

Re: The saga continues of the non-starting evinrude

Hi Tex just a thought before you strip down the carbs [ suspect not working ]can you smell excess fuel comming from the exhaust, if so i doubt any sort of big fuel delivery problems, i too have a v4 evinrude and the only problems i ever had were spark, try leaving all 4 spark plugs in the head pull off the leads and check for spark with a spare plug, as cranking speed is slower with them in, the fault could as simple as cranking speed eg. flat battery <br />let me know how you go.

Cut n' Jump.... You said "If the flywheel sheared the nut would be real loose".<br /><br />No my friend, the nut would still be tight. I've seen boaters that have torqued that (105) nut to a lesser 90lbs or so, and of course the flywheel key would shear, and did. The nut was always still tight.

Re: The saga continues of the non-starting evinrude

texas_fisherman <br />Before wasting time and money, pull #1 spark plug. Rotate the flywheel in a clockwise direction until TDC on the flywheel and the pointer line up. Insert a pencil in the plug hole and hold it in contact with piston. With the other hand, gently rock the flywheel back and forth slightly to position the piston at exactly top dead center.(furthest out position) Then observe the TDC mark and pointer again. If they line up, key is not stripped. This can save you lots of unneeded work if it check good. If they don't line up, pull the flywheel and have a look.......<br /><br />(wires don't all fail at one time)
