got my first moped off craigslist. havent got it to run for more than 10 minutes without it bogging out.
downsized the mainjet from 100 to 98, thinking it would need to go down more, and it ran nicer for a while but after going top speed (40+++) it started giving out and i havent been able to get it to run since. it starts but wont idle...
i read up on carb tuning and want to make sure i'm getting the right piece to make this run leaner and i thiiiink i need a new needle (W7 instead of W3?); seems like most folks got a W7 when they have something similar to mine running (i presume) but wanted to check with folks who have more experience first... would this help me out or should i try something else?
current bike specs:
carb: dellorto PHBG
carb size: 21mm
main jet: 98
needle: W3 ( most people on the spreadsheet got W7 so should i change that?)
needle setting: 1
air filter: molassi
hoping to fill other stuff out for the spreadsheet.
also:: spark is getting oil on it, and i think its cus its running rich... unless there is something else i should check?
thanks in advance.
