how do you clear a flooded engine?

Hi all,

Whats the best method for clearing out a flooded engine?

The bike is a husqvarna wr 125 2 stroke.

Left the fuel tap on accidently when bringing it home in the back of the van, and now wont start.

I took the spark plug out last night and kicked it over a good few times, started but died after 5 secs or so, still sounding flooded.

Should i lay my bike down on its side to try clear out the carb? or do i need to fully remove my carb and check to see if the float is operating correctly?

Re: how do you clear a flooded engine?

Try Turning the fuel tap off mate and kicking it with the spark plug in untill it starts up let it run out of fuel and stop then turn the fuel tap on and go from there hope this helps

Re: how do you clear a flooded engine?

It doesnt start up at all mate, the only way i could get it to start (briefly) was to take the spark plug out (it was wet and black), kick the bike over 15-20 times to attempt to clear out the head, dry the plug, replace and fire up.

There still seems to be fuel in the carb, and possibly some sitting in my exhaust?

Cool Re: how do you clear a flooded engine?

Take the plug out and kick it over a few times. Dry the plug off but don't put it back in straight away. Take the carb off give it a good clean out and screw the air fuel screw in all the way and turn it out 1 and a half times then put it all back together and kick it over a few times should be fine. Might need to slightly adjust air fuel mixture again afterwards to get it spot on but it should run after that

I would mate if its flooding its running far to rich. But also check Ur spark. plug and ht lead first as if its not sparking it won't burn the fuel which will also make it look like its flooding. Would check that first to be honest. Take plug out of the head and put it in the ht lead hold it against the engine or frame to earth it then kick it over see if it sparks. If it does the do the things i told u too in my last post.

Re: how do you clear a flooded engine?

I dont think the bike running rich caused the flooding, i believe its to do with transporting it in the van.

I think something has happened in the float bowl (float stuck or something similar) and i think the bowls brimmed over the top and into my engine.

Its recently had a piston rebuild and is running a higher 2 stroke oil mixture than usual to help the rings bed in. Whether this makes a difference or not im unsure.

Re: how do you clear a flooded engine?

Also, i checked the spark when the plug was out and it seems spot on.
