1994 Formula Z Sled was running good for me, but my sons brought it back with a problem last night. After they let it sit a while it wouldn't start. When they got it started the engine seemed like it wouldn't reach full power, even with with the accelerator wide open. Also seemed to be idling lower. Engine compartment smells a bit like gas, but no leaks obvious. Spark plugs and belt are new. Had the same issue right after I bought it last year and new plugs and liquid carb cleaner in the gas tank seemed to solve it for the rest of the season. Any suggestions on how to approach this to fix it for good? Also, the sled seems to smoke more than my 1992 formula plus.
formula z decreased power, harder start

Sounds exactly like mine when the idle jet came loose and fell into the bowl.
