[rsfeller]

hi gang. new guy with a first post, if this site is 1/2 as good as my saab bulletin board, i'm sure i'll be learning quite a bit.<br /><br />new used boat 4 cyl volvo (i think 125A) that has started like a champ for the 2 weeks i've owned it. on a cool morning yesterday it was having issues holding an idle and on the 5th start it doesn't appear to be getting any spark?<br /><br />if volvo/penta is like my saab there should be tricks to look for, what are they?<br /><br />she turns over great and i'll be replacing the semi worn cap/rotor/plugs/wires tomorrow.<br /><br />failure model? coil? i've read of mercury's have neutral interupts? what's that and does it apply? fuses? <br /><br />help!<br /><br />thanks gain. email me shawn@carboncow.com if you like.<br />shawn

Shawn, those 125's are cranky,cold blooded little bi$%#es....fuel is too old, they dont start....temp gets down below 60* ambient and you dont pump them enough to flood them, they dont start.....its cold and you do light the fire, they snuff after a couple seconds....pump it enough to get it lit,play throttle jockey to keep the accelerator puump shooting enogh fuel in,and after you get a little heat in the motor, pull it back to as low an idle speed as you can, the idle circuits are the richest,and will feed enough to keep the motor running......oh, and swearing like a marine technitian wont help, but you'll feel better...

Re: volvo penta no spark

thanks ODD1. do you have any tech theories as i'm really really thinking i've got a spark issue. it was atleast "acting" like it wants to start on cold mornings. where can i check for 12V? or is there any type of netural interupt?<br /><br />thanks for your time.<br />shawn

No interupt on this unit.It is a friction based cone clutch so no interupt nessesary.Your on the right track with the tune up.After all it can't hurt.Take a fuel sample to test for water contamination.Calm down.This is supposed to be fun.Stay on the same thread and you will get more responses.

Here's another little suggestion.If this thing fires off in the crank position then quits when the switch goes back to run you are looking at a bad ballast resistor.That little ceramic looking thing near your distributor that gets hot if you leave the key on.

I am having trouble trying to post a new thread...so I am replying to this one.

I have a 96 Volvo Penta 5.7L GM block. During last run, the engine died flat...no rough idel or hint of a problem. Just simply shut down.

The boat cranks over fine. Fuel is getting to the carburator. I replaced the distributor car, rotor, and coil for good measure. Still no spark.

I removed the distributor cap and cranked the engine over to confirm the rotor was spining...check. With the cap off, I put a volt meter on the rotor contact and read 11.68 volts.

Inside the distributor, there were 2 broken springs that connected the input shaft to the advance points. I replaced those and still no spark.

HELP!!!

HELP!!!

Now that has to be close to the record for digging up an old thread.

No, you are not going to post your question on a 2002 thread, but I will tell you how to post a new thread.

First go to the main page of the IO forum Click Here
Then, in the upper left corner of the page, just above the list of threads there is a button that looks like this:
