lower gearing for a single speed?

I am somewhat unfamiliar with coaster brake hubs and I need to lower my gearing. I have seen some nice sprokets available from Spooky but I am wondering about the rear hub sproket. Does anyone make a higher tooth count sproket that will bolt on? The bike is a Huffy Cranbrook in the process of being stretched and I was able to pedal it today and the gearing is just way to high- only need to get it rolling far enough to fire up. Am I correct in thinking a smaller crank sproket will reduce my gearing? The bike has a 44 tooth on it now so would one of Spookys 36 help me very much in making take offs easier? Any input would be greatly appreciated!

Thanks for all the info! I will try the 36 first and see if that is enough. Good to know the lower the gearing the more effective the coaster brake operates. I am not sure what type of hub it is as it is not the original wheel for the bike. It is a Cranbrook but the person I got the bike from destroyed the original in a failed attempt at motorizing! Great deal for me though, complete new bike and engine with less than 10 min on them for 150 delivered no less!!! I have recently tried to avoid my local bike shop as they seem to turn their nose's up when i pull in on my motorized bike- funny though its the only bike in the parking lot!! But I just might turn to them for help with the cogs if i need to go that far.
Thanks for the very helpfull information on the gearing!
I love this forum!
