I have rebuilt an engine and installed it but can't get it to start up.
Here's what's new:
70cc TCCD kit
High comp head
new spark plug
super stuffy crank
case matched
new bearings and seals
stuff i already had:
dellorto SHA 15:15 carb
techno bullet pipe
I have a good spark. reset the point gap, and plug gap. cleaned points. I re-cleaned by tank, carb and replaced fuel filter. So i'm pretty sure i have good fuel and air delivery.
So i'm thinking my issue is the main jet size. The motor wants to fire. I'll get a pop or sputter every now and then. I bought a range of jets but they aren't the right ones. i need the bigger thread ones. the current jet does not have any markings so i can't identify the size. Any advice on a good range to start at?
