Well I finally finished up my mower. However I have an issue. Even with it at WOT, it will not go past 2800 RPM. Even completely unloaded.
Here is what all I did with the motor:
-All of Don's oiling mods
-Clean up and smoothing of intake and exhaust ports
-ARC aluminum flywheel
-PCV ports in the block
-Fuel pump pulse port to the intake manifold
-Governor delete
-Dual 1.5" exhaust
The pistons, rods, and cam are all stock.
What could be the issue?
As far as I can see the carb is not adjustable aside from the idle fuel mixture and idle set screw. Also I have not messed with the timing on the flywheel, it currently is in the full negative position, any recommendations on this for a mostly otherwise stock motor?
