Unhappy Where do I start?

Hello Folks! newbie here. After coming home from work for years and putting all my change in a jar I was finally able to purchase another Harley after the one I had started nickeling and diming me to death.

The bike ran real well for about two weeks after purchase and then it begins. Problems listed below:
1. Will not idle at all
2. Stutters after taking off in first gear then goes
3.Makes like a coughing sound but not the same more like a pfft

It starts right up and will run with the choke out but as soon as you start closing it engine wants to die.

After doing some research there seems like there could be so many things causing these problems but I don't want this one to start doing the same thing the other one did. Spend alot of money on people guessing what is wrong.

One mechanic says it could be a head gasket another one says intake leak.
So my ? is Where Do I start?

Thanks Folks!

I would pull the carb, take it apart and check jets, emulsion tube and all passages to insure they were clear. If the cap over the A/F adjustor is still in place, remove it. Check the rubber diaphram for cracks or holes, check and set the float level and just make sure all the internals are OK. Before you pull the carb, check for intake leaks at the intake manifold where it seals against the heads. Use WD40 around the seals and if there is a leak the idle speed will pickup, that is if you can get it to idle.

Get all that done and let us know how it goes.

Good advice and Mnshiner don't just half *** the cleaning, most likely your slow/pilot jet is clogged and if you just look at it you might not see the problem.

Good advice but I use propane instead of WD40. Less messy!

Won't idle without choke. Did you check your idle screw adjuster? Should idle at 900 rpm to 1100 rpm. Good place to start...

Thanks Folks! Think I'll start with the plugs since I don't know what a A/F adjustor is and am not mechanically inclined.

OK Folks, today started it up with the best half or worse half depending on which day it is and noticed something.
When holding my hand on the right side exhaust where it exits it feels hot, left side cold.

Does this help a little bit more?

Instead of right side/left side, use brake side/clutch side.

Excuse me for being so inconsiderate. I didn't know that some bikes might have the clutch lever on the right side.

That must be my problem, have the brake on instead of the clutch pulled in.

You are an idiot!!!!!!!!!!!!!
