Ok, I'm gonna try and get it all in without forgetting.
I've been plagued with carb issues. So, float had a hole, thought I had it beat with a new float. Put it in the carb. I sand blasted my plugs and adjusted my valves prior to the new float. The plugs where extremely carbon filled due to running really rich. The engine ran about the same as it did prior to new float. So I started getting extreme on the needles to see a difference in tune. When I would take the idle mix screw all the way out, the idle would get much smoother. At any rate, I hooked the brush hog up, went out and engaged the pto. Pretty much that is when the miss showed its ugly head and from then on it ran so poor. No power, lots of black smoke and a horrible miss. Would cut anything.
So, I took it to the shop, started trouble shooting, mind you that I have been fighting a fuel leakage from the carb. Since the beginning. Cant get rid of it. It is not the high speed port. It is dropping from up inside the ventury . I think out of the idle port?! Maybe residual fuel from a rich condition, not sure. Has me confused. Gonna purchase a new carb I guess.
So, I pulled the plugs. Major carbon build up again. I think they are fouled. I cleaned the, but it didn't change. I started pulling plug wires off to find a culprit. Number 3 cylinder plug wire made no difference in running. I checked the wire and pulled the plug and fired the engine. The plug made spark, but that's not under compression. I moved that plug to number four cylinder(swapped). Now number four cylinder plug wire off makes no difference in running. So I believe I have fouled plugs.
Can a fouled plug be cleaned and reused? I thought so, but it doesn't seem so. I've ran a lot of gas engines, never a tractor and I've never had a fouled plug so believe it or not, I have no idea what to expect. Will get a new set of plugs tomorrow when I go get my hydraulic hoses made up.
I'm hoping a new carb and set of plugs fixes this. It feels electrical as much as it does fuel related. I suppose the fouled plugs would give me this conclusion. I'm using the Petronix electronic ignition. Could there be an issue with that? Would running to much resistance to my coil be a prob? I don't know if my coill is a 1.5 or 3 ohm unit. I've got a 1.5 ohm resistor in line. So if my coil is a 3 ohm, would another 1.5 make a problem? Gonna buy a multi meter tomorrow as well to check things.
I've put so much time and great effort in restoring this tractor and can't even use it. I'm very heart broke at the moment because of these troubles. I am at wits end with the carb. The float is adjusted properly, the ports and jets cleaned countless times. If I've had the carb apart 20 times I imagine, trying to clean clean clean, adjust this or that. See what or if something was a problem. New is all I know to do now.
So yeah, it started the morning running pretty fair...no load though, To missing and running horrible, now cant rectify with cleaned(but the same) plugs, cleaned carb....nothing changes it now.
I even checked the radiator to see if I could have a blown head gasket. No water in oil.
I'm just gonna start throwing money at it now cuz I have no other ideas at this point.
Could plug wires be and issue. I bought some stuff off eBay. They are the hard wire type( stranded wire inside). Should I get a good quality set at the auto parts store? Like maybe I'm getting a weak sparked is why I'm getting this rich condition no matter what the carb does. Any thoughts at all, plz share.
Thanks,
