Not trying to be real scientific or technical, however, on this incline, if the engine is gravity fed and in one direction of the incline the tank is below the carb, no fuel flows and depending upon the relationship of the carb float to the incline in the other direction the float will not drop far enough to let fuel in as it thinks the bowl is full. It may be as simple as they started mowing in a different direction. Newton and I ate from the same apple tree. Have a good one. Geo
Thanks Geo, I considered that as well.
Here's where I'm at on this machine:
I put on a new fuel line without a filter (just to rule out a filter problem).
Once I conquer this machine, I'll re-install a filter again.
I checked the O-ring in the jet, it wasn't flattened out, but I replaced it anyway to rule it out.
I can get the engine to run on level ground for 2-3 minutes and then it sputters out and dies.
Once I move throttle to Full Choke, I can restart it with no problem.
It does get finicky when restarting and it will stay running as long as I play with the throttle cable, engaging the choke back and forth.
It still seems to "want" to run rich.
if I spray starter fluid in the throat, Fully choke it, it will start. Then I can back off the choke to open the choke plate wide open, and it will run 2-3 mins and die again.
Now about the Fuel Tank Cap:
I ran all the above mentioned test with the fuel cap off.
I should know this, but I'll ask anyway,... is this an acceptable way to rule out a clogged fuel cap?
I'm still stumped, but determined to get it solved.
