ADVICE:Baseline carb jetting/engine timing/spark plugs

Find the point where the engine kicks back on your starter.

Set up the distributor so you have some room to advance it without opening it up.

You find the starter kicks back at 20* initial. So you set your initial limit at 18. If you want to start at 33 total and range up to 38, set the distributor with 20* mechanical, 38-18, and initial at 13*. Then you can start feeding timing in up to your 18* kickback limit.

You may have to reset your idle speed as you dial in more initial timing.

Once you find the right total number, subtract 18 from it and you have your mechanical advance number.

That's one way to do it.

Timing first as mentioned

IMO, carb is small. If you decided to go up in sizing, grab a proform style mainbody. Make it about an 830.
