Performance up-grade for a M151A2

Post by Weehunt » Wed Sep 25, 2019 9:08 am

Has anyone made any up-grades / performance changes that have effected the power, mileage, HP with your M151A2 MUTT engine? Has anyone played with compression or exhaust manifold.

Look under the modifications section.
I've only tweaked the inside of the carb by removing (polishing) all edges and bumps in the throat and streamlining the edges of the throttle plate, Choke plate and securing screws. I did not mess with venturi diameter. She seems to gain a few HP by just feel, but it's not much.
There have been attempts to make the engine more than it is (or needs to be)
