Hey JD lovers. I just picked up a flat fender 110 this week at an estate sale. (Type:0643 S/N:251946...1972...year I graduated high school) The guy said it was running within the last year. But, I can't get it to fire up. I'm not a small engine expert, but I do rebuild small engine carbs all the time and am dangerous trouble shooting electrical stuff...and I don't think this is rocket science. If I have fuel and spark it should at least fire up, right? I have both. I'm sure I'll need to go thru the fuel system, rebuild the carb and put a tune up kit on it, but I wanted to at least get it to fire up before I did all that. I pulled off the air breather and gave it a very little shot of ether and it did not fire up...even though I know I have spark. Any suggestions? An interlock issue somewhere would kill the spark, right? (I've been running my LX176 that my sister bought new in 1992 for over 15 years. And babying that high dollar plastic hood.) Thanks for any help.
