Okay I have an update, I really need help now. :bash:
I checked spark on the non firing cylinder by putting a new plug in the wire and leaving the old one in while it was running, great spark. I then replaced the spark plug in the machine with the new one that was just sparking. Started the sled and still no fire on this cylinder, unless I took the sled out a ran it hard, then the cylinder kicked in, but only till back at an idle. I then pulled the wire off this plug while at idle, no difference in idle, tried the other two that where firing and witnessed a certain diff. in idle. I conlcuded the spark is there and no problems with electircal.
Second I switched carbs with on of the working cylinders (belt side cylinder is the one not firing, middle and chaincase side are working) the one I swapped it with was the middle cylinder, guess what...no change the middle cylinder still fired fine and no fire on the belt side cylinder. I am at a loss for things that could be wrong, can anyone help?? :bash:
I should also note that the when I raised the belt cover there was oily sludge on the bottom suface, inner (motor side) off the cover. Could this have anything to do with the cylider not firing? Maybe a bad crank seal or something??? There was also a light residue of gas on the floor beneath the none firing cylinder muffler outlet.
Any help or suggestions at this point would be GREATLY appreciated!!!!
