Series engine turns but doesn't fire

lloydiee123 · May 27, 2012

My landy has stopped firing my spark plugs fire and there's fuel going into the carburettor, I brought new sparks plugs which are set at the right distance the fuel is fairly old but I'm not sure what's quite wrong please help thanks Lloydiee123

Are you sure that the fuel in the carb is getting to the cylinders, I.e. do the plugs smell petroly after turning over for a while?

If they do, then the plugs may firing at the wrong time so check points and dizzy. Have you put anything new on recently or did it just stop working?

lloydiee123 · May 27, 2012

Haven't done anything recently just stopped

I swapped the fuel earlier and it still doesn't start

lloydiee123 · May 27, 2012

I just checked the cylinders and it does smell of petrol So what do I need to do to ensure they fire at the correct time? Thanks again

How good is the spark? Fat and blue or thin and yellow? Poor spark can be caused by points gap changing with wear, the condensor starting to fail or the coil failing.

The spark is very bad and its thin and yellow/white so im going to purchase a whole new distributor unit

points, condenser(if it isn't electronic ignition converted
cap and rotor

where are you?

Ok thanks, I'm in Gloucestershire

If it failed to fire suddenly (rather than getting worse over a period of time) then try just replacing the condensers. Easy and cheap enough to do and even you end up replacing the dizzy they should be replaced anyway.

Have you an amp meter fitted? I have had a few that give your prob , try a wire straight to the coil,

lloydiee123 · May 31, 2012

I have now fitted a new coil and the spark is good but the problem know is for reasons beyond my the fuel seems to be set a light in the carburetor instead of the cylinders?

sounds like timing is out...

spark firing when induction valves open...

lloydiee123 · May 31, 2012

so how can I adjust the timing to get it correct? thanks

nick2303 · May 31, 2012

dizzy could be loose, if its turned it will throw out the timing, could be the reason it stopped running b4..

ya need a strobe...

ujnless someone on ere can tel ya how to do it without one...
