You can buy as many jets as you want. GMP has said in another thread that the slide is important. You should be able to work with a #7 easy enough. The magic is in the needle as this covers probably 75% of your throttle movement. A needle that is too rich for the purpose will always be too rich even with a pilot small enough to cause bogging off the bottom. You really need to know what you have before you can know where to go.
