Cold petrol??

[st3v3]

Odd one here, I haven't had the bike running for a couple months and it used to start normally after 30 kicks or so...

But now its different.

There is a very good spark from plug.
Battery is healthy and not an issue anyway.
Coil is connected (hence spark).
Petrol is flowing and adequate - but nothing.

Now, when i sit the plug on the cylinder head it sparks and the compression is very good but nothing, is the petrol too cold to 'make boom'? it's not flooded either, well not really.

Are you sure petrol is getting through.

Petrol will be ok.

Yep, had fuel system apart, carb off and checked bore/reeds.

There is traces of petrol about and all the ingredients of a running engine are there; it's just not running.

Take the plug out, clean it, warm it up, put a little petrol in the plug hole, put the plug in and see if it fires up.

take out the air filter and spray easystart, or similar*, in there while cranking it over, it may take two people.

If it fires then you know its likely to be fuel related. If it doesn't fire then its something else.





*I've heard of people using wd40, hairspray, and even lighter fuel to similar effect, it may work but I'm not going to try it

Iv tried deodorant; not much joy but im gonna buy some easy start today, might help with the car later too....

I'll add that to the list

Did you try lighting the spray before you sprayed it in the carb?

[reckless_b]

your petrol may have "gone off" these days petrol seems to go off rapidly if left, I had a kawa gt550 and if stood for about 2 weeks it would run like a pig untill it had some fresh, only today I've pulled my 600 yam radian out of the garage to have a de-stessing ride,back to work tomorrow, and this too ran poor, its been stood a few months, it would only run if it had at least half choke, it felt as if it was only running on 2 or 3,I too checked all the usuals spark etc, finished off by draining the tank, I'll give it a gallon of fresh tomorrow and see if it clears. By the way, I'd suggest draining the carbs as well, usually a drain screw on the float bowl.

If normal is 30 kicks I would say there is something else amiss there

I've found a good trick is putting your spark plugs in the oven, getting em good and hot, will almost always revive a non starter provided there are no drastic faults.

thats why you use a long reach socket with some bog paper stuffed in it not a plug socket.

You could try firing up a blow torch and aiming the flame through though hole in the open tank lid?

Should warm it up.

That's a possibility, but my mummy doesn't let me play with lighters

Yes, the petrol is too cold that's why the engine isn't starting

Easystart is good stuff though some say that it's bad for the engine over time.

As it's VERY highly combustable the engine will run on the stuff alone for a few seconds. This means you get some initial heat, but more importantly as the engine is "running" it'll burn any excess fuel and draw more fuel through to continue.
It's also good for testing a block as you can spray it into the cylinders without a carb even being fitted and the engine will run breifly.

I used to have a MK2 Golf diesel that I used to start up by spraying cheapo deoderant into the air intake - Worked there, but that was an engine with high compression so I guess anything that burns would get it going!
I'm not sure how that'd go on a 2 stroke but if in doubt Easystart is king* (*But it may kill your bike in time and is no sustitute for sorting the problem out properly later).

The stale fuel story rings true too, as does the fact that machines don't like resting for too long.
When I get my Lawnmower out for the first time every year I have to clean it out and use a little easystart to get it going, but after this it's good for the season.
