Hello all! I am new to this site, and really hoping for some assistance. I will hit you with the basics. 18cc, with Chinese carb. At most would start & immediately die. Checked and cleaned fuel filter & lines. Purchased carb kit. Disassembled and thoroughly cleaned carb. Reassembled. Same problem. Took back apart. Removed welch plug to get to idle ports. Installed new welch plug. No better. Obtained plastic caps to be able to remove mixture screws. Removed (dropped) one is slightly longer than the other. Tried in both location, and with multiple adjustments. "Now" immediately floods and no start. I obviously "bothered" something. Removed and cleaned & gapped plug. Started to think maybe the fuel was too diluted. Drained and added 2-cycle oil to fresh gas. I even added a dew drops into the cylinder due to being previously flooded now. Pulled like it was going to start, first couple pulls. Flooded. You just got the short story. Carb has been apart several times. Cylinder oiled several times. No longer remember which mixture screw I last put where (for the high and low/longer/shorter). The worst part? I have rebuilt thousands of carbs in the automotive industry for years as that is one of my trades. I am beginning to think this weedwhacker is 2 stokes short of me understanding!

I have a John Deere LX176 with a Kawasaki FC420V-ES10. My engine manual, and the posts in the forum, indicate a separate coil and igniter. My Deere only has the coil, which I understand has the igniter built into it. Question is, do I set the air gap the same (.012), and is there a test procedure (ohms) for this coil?
