Anyone have high and low jet settings that work good in the winter? Runs perfect in the summer and will go good in the winter top end just doesn't like to stay at idle. Also hard starts..rovan 305a.

Unfortunately theres "no one size fits all". Trial and error,write down you working #s so you can easily go back to those setting.
Each engine's going to respond differently to cold, heat ,humidity,etc. This is where you learn to tune you specific vehicle to run correctly for your situation.?
Good Luck?
 
Thanks ill keep messing with it. Should these be rich for cold weather? With the b5 paddles on a frozen lake it is a blast. Drive up on a snowmobile they don't know what to think. Especially with the pipe sounds like a snowmobile to.

Most likely it will want to be leaned out , make small changes ! ( turned IN )
 
I should note i have a dt1 triple layer filter, velocity stack, and outerwears over that. Ill make some adjustments after this nor’easter passes.

Like SeanD commented , cold air = richer carb settings. I also strongly suggest waterproofing your electronics, and bring a propane torch to pre-warm the cylinder to assist in easier cold startup.
 
Northern maine. Just took off the studded tires for lake ice runs now paddles for snow. Electronics stay fairly dry i coat the whole thing in maxima sc1 and it repels water also snow doesn't stick. Ill have to pick up a heat gun. Thanks
 
I spent a few winters out on the ice with my Savage nitro mt, moisture wreaks havoc with the servos. You can seal them with rtv, and wad some grease around the splined output shaft. Some guys also used small balloons . You also need to seal the tire beads or water will saturate the inner foams and cause major rotational imbalance. I used to wrap the engine cyl with aluminum foil to lessen air flow so the engine could reach operating temps in the cold. My nitro winter bashers.
