Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
Any help and information greatly appreciated.

The studs in the sprocket hub are stripped out. The hub is probably walloed out also. Probably will have to have a new sprocket hub. I doubt I have the ability nor the tools needed for this job. Thanks for all suggestions/opinions!

Just picked up a 2008 Big Bear 250. It was sitting for about 1 year it's definitely a project. Currently chasing down a no spark issue. Imagine that lol
Tons of info around the forum. I look forward to learning!

So title tells all. achine was sitting for two years untouched.
I will post a picture with diagnostic path so far.
Replaced defective start solenoid, starter grinding but engaging.
Replaced all wiring in #1 splice with dark green, brown and red/white wires. Checked all other junctions.
Pull start works phenomenally and starts instantly.
Kill switch does absolutely nothing, but the key will stop the bike and allows it to start. Replaced key switch and pigtail at key switch. As of now all lighting is functional (was not before fixing it)
The Good:
-has new spark plug
-valves were adjusted
-key switch
-wiring appears in order after repair
-display functioning
-new battery
-always starts easily on pull rope
-etc switch
-pulsar coil
- ignition coil
I am replacing the bendix due to intermittent failure and gapping the pulsar tonight. Also, replacing battery cables and unplugging kill wire from cdi to isolate. Replacing battery wires to starter and ground cable.
