Gt 175 high speed "miss/bog"

Mine is not nearly as clean as the example you posted but I believe all is well with the linkage. Is there something else specific I am looking for ChampioNman?

Looks like the red lever on the primer is turned a little.

Thanks for the reply ChampioNman. I will pull the air box tonight and confirm travel on everything as you describe.

I may be leaving out a key piece of information. Last fall I blew a head gasket and started to notice the issue intermittently after getting the boat back from the head gasket swap. I'm thinking firing out of order, as opposed to intermittent cylinder dropping, could easily pop a gasket?

Does this point more more strongly towards pack and/or trigger? Could a failing stator surge badly enough to cause an out of time discharge?

hard to tell in that pic whether the roller is there?? i zoomed way in but it was still hard to see.

The throttle roller is present although likely not original as it looks like it is just some clear plastic tubing slid over it.
