I'm ordered a couple Chinese CT70 replicas (72cc) with Lifan engines and Walbro PZ19 carbs--which I'm assuming are the same as Keihin PZ19s.

I live at 7700 feet of elevation and that's the lowest I'll be riding at. Average will be 8200 feet and the highest will be 12,000 feet. Temps will be in the 50 degree to 80 degree range. I don't yet know which jets will come with this carb, but they will the stock, sea-level jets.

1. What type of Keihin pilot jets are used in this carb? I know I'll need the small style 7mm main jets.

2. Can someone give me some jetting recommendations for this elevation? I'll be using either the leanest or second-leanest needle position.

Thanks for any help you can offer.
