I recently picked up a 91 Marathon with a 3PG and the thing was a DOG. I am trying to get it tuned up/faster. So far I've:
Checked compression: 160psi
HEI upgrade: Installed and works fine
Put Seafoam in the gas tank: Still running it through
New fuel pump, lines & filter
Pulled apart the carb and cleaned / drilled main jet
I haven't driven the cart since the updates but it runs well without a belt.
The problem:
I can't get full throttle - nowhere even close and looking at the setup, I can't see how the pedal armature nor governor pivot would provide enough travel for full throttle.
Is this normal? How do I fix this? I am thinking about pulling the throttle cable off the governor all together and rigging up a bracket direct to the carb but would rather keep it simple if possible. Thoughts?
