Vacuum and fuel lines

[RetroBrian]

Ive had my scoot for about 3+ months now. I bought it new. It now has 350 miles. I've changed out the oil and gear oil at both 100 and 300 miles for break in. I changed out the CDI to an after market and coil and wire. The only issue I am really having is ...I dont think the auto choke is working right. it turns off too soon before the engine is warm enough to not stall. I want to change out all the fuel and vacuum lines. What size and how much should I need...length wise.
