They would have never put a diesel head on a Quickie .40 engine. It might work, but the nature of the engine was all out racing performance. it would not be useable as a sport engine. it is like trying to drive a dragster on a busy city street with stop and go traffic.
You have a Fox .40 engine. it will work fine as a diesel.

Pictures can be a problem. You need to make sure the pictures are saved as a JPG or JPEG image format. Resize the pics to 640x480 as many people can't view them if they are larger and most forums will block images that are too big as well. Then you upload the pics to a photo service such as Photobucket for example. Next copy the link from the photo service and use the picture icon in the toolbar above (insert image). Then the pics will appear in the message you are posting. I think RCU has a minimum number of posts you have to make before you can upload posts to RCU.
