ignition timing advance parts wont throttle up

[mr.trot]

hp 85 3 cyl. 2 stroke. Won't throtte up. Appears that linkage for spark advance is broken cant find parts diagram or photos to compare. I can manually pull up all 3 carbs with side linkage and throttle up ok but ignition advance cam under flywheel is suspect component. ANy help would be appreciated

Hey! Who is the manufacturer of the engine? And what year was it built?

It's on the Force/Chrysler forum.

Have someone turn the prop as you shift into gear.
Then you look at the linkage under the flywheel and see if it advances like it should.

The parts are usually plastic and over time they get brittle and break.
They are available.
