You need the Service Manual, James.

There isn't any timing to set. If you have spark, and the flywheel is on correctly, it is timed correctly.

The motor needs good compression, spark, and fuel.
Is gas actually getting to the carb? Pull the fuel line and see of gas runs out with the fuel shut-off and tank vent open

The 1958 model was designed for a gasil ratio of 16:1, but BRP now suggests 20:1

Thanks for the link JB i will get 1

tx1961whaler: fuel is getting in i have tried putting petrol direct in carb and in cylinders and it still ent working there is adjusment screws for the points

i know its got good spark just dont know if it is sparking at the right time could this b possible

Thanks

Re: 1958 evinrude lightwin 3hp how to test timing

Unless you have the spark plug wires swapped, it is impossible for the timing to be off. Putting the lever on the "start" position automatically sets the timing.

OK, you know it has fuel. Does it have enough compression?

Re: 1958 evinrude lightwin 3hp how to test timing

i havent tested the compression with tester i will do that in the morning.
with the spark plugs out it seems to have quite a bit of compression

wot should the compression b?

thanks for your help

Re: 1958 evinrude lightwin 3hp how to test timing

hi i have tested the compression and its ok
still wont start

are you 100% sure that it dosent need timing because if i was to put new points on how would i set them up and there is timing marks on flywheel 1 big notch and 1 small notch on oppsit sides and two lines on base

When you install new points, you set them for a 0.020" opening when the cam lobe is at the highest point under each point's rub block. The flywheel is keyed to the crankshaft with a woodruff key and is not moveable.

Re: 1958 evinrude lightwin 3hp how to test timing

ok then i will check the gaps

when im trying to start it after loads of pulls it will just pop and smoke will come out of hole were water should come out for water pump

thanks

Re: 1958 evinrude lightwin 3hp how to test timing

Those holes are the exhaust relief. Some exhaust is supposed to come out there. So that is not a symptom.

You say you have spark. But how much spark?? Will it jump a 1/4" gap? And what were the compression readings?

Obviously, there is something that you are passing off as OK, that is not OK. There is no excuse for doing "loads of pulls". That motor should start easy. All we can do from a distance is use the clues that you supply and then make an educated guess.

Re: 1958 evinrude lightwin 3hp how to test timing

hi the test shown 50 i used a car tester dont know if that is ok

i messed about with the points last nite and now i have lost the spark

but when i did have the spark i dont think it jump a 1/4" gap

can you tell me wot i need to do if i was to put new points in then that might get the spark back

thank you for all your help

Re: 1958 evinrude lightwin 3hp how to test timing

Clean and reset/regap the points to .020, a business or note card saturated with carb cleaner makes a good final points cleaner. Insert it when the gap is open, close the gap and gently pull it out. What kind of replacement plug wires did you use? It needs solid wire core plug wires, not wires from an auto parts store. Sounds like you don't enough spark to fire it off.

Re: 1958 evinrude lightwin 3hp how to test timing

50 psi compression is not enough. It should have 75-80. You may have a blown head gasket. And obviously, you need to get the spark back.

Re: 1958 evinrude lightwin 3hp how to test timing

on the cam lobe it has TOP stamped on with a line either side do i need to be on 1 of the line or in middle of the two?

my plug wires are not solid wire core would that make a big difference?


the gasket looks ok (clean) i will get a new one to be sure

were is the best place to get the parts?

and how much touque do i use on head bolts?

many thanks

Yes, the spark plug wire MUST be the the solid (wire) core.

Re: 1958 evinrude lightwin 3hp how to test timing

i think we r nearly there

i have a good spark now and the compression is 77psi
my tester is old so i used a mates and its ok
but it still wont start
when im trying to start it petrol is coming out were the choke lever is could that be the reeds or something making it flood itself

The carb float is stuck open.

Did you replace your plug wires with solid core? As noted above, you MUST have solid core wires. Automotive wire will NOT work. Absolutely, positively will not work.

i have now fited solid core wires and still wont start i havent put new points or condencers could that cause a week spark

thanks for all your help

try swapping the plugs wires...

happened to me on a 30hp bigtwin, arms still hurt...
