Fuel Dripping Out Of Exhaust

riverracer · Dec 4, 2003

I have a 96 zrt600. Started it for the first time this season last night. Had a bit of trouble getting it started and found the floats on 2 of the carbs stuck closed so no fuel to the cylinders. Fixed that and ran great. This morning, I went to start it again and as I turned it over, I noticed fluid dripping out of the pto side exhaust. Not just a little, but enough to fill up the engine mount. My first thought was coolant, but I tasted it and it appears to be fuel. Could this be a choke stuck open? Any help would be appreciated.

Take your Carbs off and go through them good, something is not doing what it is supposed to!

CHOKE CABLE!! AS CAT 2000 SAID, GO THRU THE CARBS AND CLEAN/SYNC THEM UP. I WOULD BET THE CABLE NEEDS TO BE ADJUSTED(NOT ENOUGH THROW). I HAD THE SAME PROBLEM WITH MINE. WHILE THE CARBS ARE OFF, PULL THE REEDS, MAKE SURE THEY LOOK GOOD. AFTER ALL COMPLETED YOU MAY WANT TO CHECK COMPRESSION

Leaking Needle & Seat ,or Float set too high.

I tore all 3 carbs down tonight and cleaned and rebuilt them. Couldn't find anything obvious as I had cleaned and rebuilt them 2 months ago. I'll install and resync them tomorrow. Could any one of the three carbs cause fuel to leak out of the pto exhaust or just that one?

Just that one.

I put the carbs back on and it seems to have fixed the problem. One heck of a big backfire when I went to start it though. Must have been from all that fuel vapor in the bottom of the crankcase. Blew the exhaust pipe out of the header flange. Hopefully I didn't cause any damage. Seems to run O.K. now, I'll do a compression check to see if everything is normal. Thanks for the help.
