I do not own a Jett 1.20 but I do have a Sport Jett .46 and .50. After running both of these engines very hard for some time now I am convinced you can not buy a better engine any where. They are easy to start and adjust and power for their size is well beyond their competition. My one experience with service is very good. The turn around time is quick and the price was reasonable.

You pay a little more for a Jett but it is well worth it in my opinion. I use mine for speed so high rpm and a little too lean at times is not uncommon. They have taken the abuse and keep running great. One thing that I have noticed is that any claims on their web site seems to be fact. Check out my web site with videos of my Jett's in action.
