At my wits end. My MTD Yardman 42" tractor, cranks, won't start.
It has a new battery that charges well, new air filters, new spark plug, cleaned and rebuilt the carburetor. The solenoid was bypassed when I bought it, and it worked fine without it one season. This is the second season I have tried to use this tractor, and it has been nothing but one problem after another. The (Walbro, LMK) carburetor was leaking fuel, so that definitely was a problem.
I have also recently replaced the belt for the blades.
The 20 amp fuse was blown and I replaced that.
I read this:
Cranks - Will Not Start
x Fuel tank empty
x Fuel hose kinked, pinched
Fuel filter clogged
x Fuel valve shut off
x Fuel solenoid inoperative
LPG regulator not opening (?)
Water in fuel, stale fuel (?) maybe stale but the tank is full?
x Wrong type fuel (diesel)
x Throttle control in stop position
Choke not fully closed (?)
x Choke on, flooding hot engine (not hot.)
Power take-off (PTO) clutch on (?)
Safety interlocks inoperative (?)
x Spark plug wire disconnected
Spark plug improperly gapped (?)
x Wrong type of spark plug
x Wiring harness not connected
Wiring broken, loose or wrong (?)
Transmission not in neutral (?)
Electrical clutch not adjusted (?)
Cranking speed too slow to start (?)
x Spark plug loose
Low or no compression (?)
I am thinkin that maybe I don't weigh enough to hold the seat down properly for the safety switch, but how would I disable that?
Some of these things, I don't know how to do. I am so tired of fiddlin with this thing, but if there is a step by step how to check more than what I have already done, if someone could link me, or explain, I would be so appreciative. Thank you.
