Hi to all I have a pk80 from cheezpks with NT speed carburetor I'm planning to buy new jets set. Did you know what the stock is?thanks in advance.
Gustavo.
Stock size is normally a 70 jet. Some come with 72 as well. If you wanted to make drill your own jets you could get 61-80 drill bits for under ten bucks as well as a some solder and use your jet you already have as well.
Well I do it. happens I have the micro drill first l check the size it was 69 .I used 68 (more big)and carefully drilled. Just one size big and the difference is badly big. Lost tork and speed. I can't believe the difference. I reopen the carburetor check and clean all and nothing happens. Next move ls to install a new one.
The power is back! I find a jet from regular nt I checked the size it's 70. Is one size less than the original now it's more powerful than in the beginning. So a little change do so big.
Sorry about the links, they must have sold out or taken them down. I'm glad you got your power back. I had to go to a .60 to get mine dialed in. If you are still having trouble with any 4 stroking or if you hear it missing it's good to have some on hand. I think these links will work.
