Mower is a couple years old, pretty low hours. It has the toro 24.5 v-twin engine. It has always started well with throttle at idle, choke, and started right away. Now it won't start cold, but does restart fine once warm. That first cold start it tries to fire and idle but just won't quite take off. I start it (cold only) with starting fluid and it starts right away and runs great. So,....I was thinking fuel problem. The in-line filter looks fine so I thought fuel pump. Before changing it, I did the following.
New battery (needed it, only had one chance to get it going).
New plugs (didn't need them but why not)
New air filter
Check fuel lines for cracks/holes
Check plug wires for arcing
Check that the choke was closing completely
Removed in-line fuel filter and hooked hose direct to pump (just to check, I was sure the filter was fine, and it was).
No change after these items, yep, still thinking fuel pump. Replaced the fuel pump, no change. Still starts immediately with starting fluid and runs great, will restart just fine once warm.
Dirty carb? Valves out of adjustment? I am lost. Any help is appreciated!
