Ok, there's quite a bit of background on this one so please bear with me. I chased a sudden loss/restoration of power for quite a while before figuring out that it was the DSAI system. Replaced with the coil kit to fix it and that problem is gone now. In the process of trying to figure out what was wrong with it, I messed around with a bunch of other stuff that I wish I had left alone. Now the mower runs fine without load and I can mow with it OK. The problem is that when I hit a patch of thick grass mowing at or near full speed, it sometimes wants to die and I can smell gas. I can back up and wait a second and it comes back but is not performing anywhere near its previous level.
-replaced fuel lines/drained and cleaned gas tank
-replaced carburetor
-new spark plugs
-made sure governor was set with the shaft fully CCW (WOT RPM @3700). Slight surging at fast idle.
-air filter/system seem to be clean
I suspect that this may be a carburetor issue but am not sure. The carburetor only has one screw and I've been hesitant to fool with it as I'm afraid I'll make it worse. I have a manual for this engine (CV-740S) but none of the carb adjustment procedures seem to apply to this carburetor. Any help will be greatly appreciated.
