Carb Issues - Jetting Lean and Rich Questions

Okay so here's my dilemma my scooter 1987 Honda elite Se50 would bog down low but once it picked up speed it traveled just fine. SO i thought i should have a look at the carb and once opening the carb i noticed the main jet and threads were severely stripped. So I threw out the carb and replaced it with one from 93 SR. The main jet on the 93 SR carb is an #88. So i thought i fixed my issue but my scooter would not travel past 15mph. Took the airbox off and im going 30 but when i hit 30 it wants to cut out and speed falls back to 25 then creeps up to 30 again. My scooter runs better at night and when there is low gas in gas tank. Also since the carb is from a 93SR l the oil outlet line is supposed to go to the carb insrtead i have it hooked up to intake manifold, could this also be a factor.
Also in the service manuals it shows there is a slow jet #35 but mine is missing from the carburator. I hear that the PA carbs did not come with a slow jet but service manual says otherwise. What are your thoughts guys?

Get a carb from an 87' SE50. I have one on the shelf if interested.

Greetings:

I guess Honda-san is calling the pressed-in brass standpipe a "jet". They can be coaxed out but the risk of damage is significant.

If missing altogether, you will have an issue. The main at 88 is way big, but otherwise the carb should work if all the parts are there. Consider a 78, and get a good temp gauge to monitor.
