when you find a dead cylinder by pulling the spark plug wire, you can determine if its dead from lack of fire, or some other issue. If you find you have two cylinders that have no fire, you look at the trigger, three on one side, look at the switch box. If you have two side by side that have fire but are dead, you may have a flooding carb( or no fule to the carb). You can fine tune your diagnosis by using a spray bottle with soem gas in it. Once you find the offending cylinders, spray a little gas down the carb throat, if the cylinder picks up, you know its not getting fuel. You get the idea?

I started it up today in my driveway and there was massive grey/blue smoke for the first few seconds. Would this indicate a carb being flooded? I just rebuilt them a few weeks ago but this problem was happening before the rebuild. The only thing I did before that was rebuild the fuel pump. Is it possible to screw that up and cause the problems I'm having. I hate second guessing myself but everything ive done has been a first for me.

Fuel pump is a definate possibility. Does this engine have oil injection on it?

Have you checked to make sure your not pumping oil back into the crankcase from your oil tank? I had the real bad smoky starts on mine and found that I was overfilling my oil tank and it was pumping oil back into the crankcase when I shut it off.

My tank is only half full and the color of the smoke leads me to believe its burning excess gas. I did have the fast idle lever up pretty high so it kind of roared to life. POssibly that had something to do with all the smoke. I guess I'll look at the carbs and fuel pump one more time before taking it out again.

I didn't take it out today but did run it in my driveway and pulled the plug wires. Here's what I found. All had spark. Cylinders 4, 5, and 6 caused the engine to noticeably bog down when I pulled the wires. 1,2,and 3 did not cause the same change in engine speed. They did however have spark and when I put the wire close enough to the plug the spark jumped and caused a slight pick up in rpm's. Can anyone tell me what this means???
