Looking for some advice on my 49 A. I bought the tractor last summer at which point it had filled the crankcase with gasoline. I went through the carburetor and put new points cap condenser rotor wire on the mag. She runs real nice about 95% of the time. However, theres 3 things she does that are odd to me that I am trying to troubleshoot:
1) Starts hard. She spins over fine and pops off but doesn't start right away. She'll sit there for maybe 5-10 seconds going pop-pop-pop-pop until she finally runs regular. I though it might be a air restriction so I pulled the oil cup off and tried to start her but she sounded the same.
2)Misfires occasionally under load, sometimes severely. I was plowing last night (2x16 in clay) and she pulled the plow very well in 2nd gear. Never lugs down but occasionally she misses and sometimes misses successively, on one occasion killing the engine. There seems no telling when she'll do it though and she might go 20 minutes between misfires.
3.)Hesitates and makes a load pop almost like a backfire but not so distinct when she comes to the bottom of a hill and is about to start climbing another. She does the same thing when you engage the clutch rapidly without easing it in.
I will be trying to post some videos shortly. Thanks,
Pete
