I just got my DS runing on alky, and it runs good, very fast. The only thing is that it seems to have a flat spot from half to full throttle. I know I cant check the plugs so does this mean lean or rich, should I change the main or needle position, and up or down. I am now runing a 300 main and 95 needle middle notch, and a 55 pilot with pump. I have heard that the only way to tune right is to use a EGT sensor, where do you buy one for a DS? Could I be runing the bowl dry, where can I get a high volume low pressure fuel pump and how do you install them?

 

Mid is needle. You are probably fat and could drop the needle a notch. Careful though. . . don't go too lean.

 

you can use any egt guage out of summit. as far as the probe you need to order one from a place like dennis kirk. the probes for the sleds are smaller than the ones for auto use. if you do order one for a sled l would suggest getting the more expensive fast reacting ones. no need to wait for them to warm up. i have pics of my setup posted
