Exhaust leaking a little

Metallica19991 · Post by **Metallica19991** » Sun Nov 18, 2007 11:27 pm

i have a kec 340 ccw 1973 engine.. and when it starts little gas droplets come out of the exhaust. and it get worse once the engine is starter.. is this a sign of a flooded engine? but the engine starts so does that mean its not flooded?

It is gas right? Not antifreeze?

I'd guess it to be gas, Nick.......there shouldn't be any antifreeze in a fan cooled engine....lol

Yea Its more than Likely Gas, I wanted to cover as many bases. so he/she could double check.. I reread the post. Yea. I guess 1973 was probably Fan cooled.

In my experience,. if you've got an engine throwing black goo out of the exhaust, you probably a cylinder not firing, or not firing properly. Usually you can see which one the goo is coming from.

Ok yeah it is shooting out black goo... so you guys think the engine is only running on one cylinder?

also i have another engine and its a kec 340/5 engine.. but it doesn't have the clutch. and the shaft is 25mm.. does anybody have a clutch that will work for this engine that i can buy off them? if not then could somebody find me a clutch that will work? i needs to be a belt clutch like the original.. because i dont know what clutches will work and will not work for this.. so if somebody has one that will work i will gladly buy it off you. or if somebody could find me a clutch that would work that would be great! the engine is a kec 340/5 and a 25mm shaft.. i now have 2 of these kec engines. i think im just going to give up on the 1973 engine and work on the kec 340/5 engine.. so does anybody have a clutch? Thanks for your guys time..

Mettalica,
The engine you have with the 25 mm clutch is a '72 KEC 340/3.

Metallica,

The Walbro carbs have the number on the top flange where they bolt to the intake. They will have a Walbro part number on the left side of the flange like WDA-32, WRA-31 you get the idea. Looking at the carb from the recoil side it will have stamped in it Walbro Cass City, MI. Not sure because I've never had a Bendix before, but photos I've seen show a metal tab on top of the carb under the adjustment screw that show which direction to adjust the screw for richer or leaner.
