Some tips from alky that might help.
Heath said some have more issues then others, and having the right jetting sure helps. The race carbs have no choke so they may need a little help starting up.
When it gets cold the methanol cars are also hard to start, I hated cranking any motor, specially cold so use to shoot a little gas down the throat of the Dominator on the first start up and usually had instant starts.
To warm up injection guys lean out the motor by partially closing the fuel shut off bypassing some fuel back to the tank. Carb guys can set up a small vacuum leak port with a nipple and small valve. Mine I would loosen a small plug on the intake for a couple of minutes, don't forget to re tighten!
If I was using the nipple and valve I personally would put a plug after to insure no vacuum leaks when racing.
There are guys that have a rod or cable hooked up to the valve so they can open it any time to insure the right temp after the burn out if still cool, I never needed that and again don't care much in case it would stick open or leak.
Caution a similar set up is to put the small valve at the end of metal tubing and manipulate it from inside the car but I never cared for that idea either, specially if a car has NOS too.
My alky Dominator was set up rich and never had trouble after that first start and warm up. A shot of regular down the throat, loosening a plug on the intake for 2-3 minutes and it was good to go. On the way to the lanes get a turn over of the coolant then kept the fan and pump off and just tickle the switches on and off to get a decent temp reading was all I ever really needed. This was alky, E85 should be much easier.
I remember reading years ago about a guy that set up a NOS fuel tank, solenoid and fuel plate under his carb. He had a fuel shut off for the carb and had the plate jetted so he could start, iddle and run low rpm on gas. He would use this for warm up before a run and after a run back to the pits to keep the excessive moisture out of his oil.
Once dialed in most people do not have great issues on E85, but again most of this comes from alky and maybe something here will help you.
