My stock 02 with 5k on the clock was running fine six weeks before I parked it. Then I replaced the muffler,  Emgo Dunstall Replica, put a 152.5 main, left the pilot at 52.5 and a half spacer in the carb, then a K&N drop-in air filter. at first it started fine, then it got slower, then stuttering, and of course stopped. Attempts to re-start wouldn't work. Rinning on prime, no help. When it did start I had it at full throttle only to get a steady but weak run from it. I did notice a little lite smoke (exhaust) chucked that up to new and needs idle reset. And that's my problem. I think the carb is flooding out and that I did something to the float. Can't set an idle that I don't have.

Did I mess up the float? No I didn't do anything to it. I remember someone suggesting lately to drain the carb and fuel from the tank because of Ethanol (I am almost certain that I don't use it in my gas) I drain some fuel; didn't see anything and it started right off. Idled fine then dropped off and I can't start it. Is something amiss in my carb.? No my vent tubes are not pinched. The float is my only guess. And I don't want to rip down the carb on a guess. The air flow should have made up for the change in extra fuel. I did have no spacer but when I opened the carb this time I decided that was too much fuel.
I plan to set up the idle when I get it running. And while we are talking about it, Don't laugh, where do I hook up the tach to set the idle?
I appreciate any help please.

good list - and to this diaphragm section - clean - make sure the slide is clean - not oil grease - nothing on the slide.

Sounds like an engine with no fuel.

I vote with Greg.....pull the float bowl off, check any jets you touched but also the float and the needle very carefully....sounds like too much gas and is flooding.  Note it started up well after draining the carb.

Also, if it were only an idle adjustment it ought to run fine holding the throttle just a little to keep it idling.  Doesn't sound any where close to that condition.

Check the float and valve needle/seat...any spec of dirt can hold the valve needle open.

Also, you didn't mention...did you have the slide and spring out?  If you did make sure that is in right.  You can check by blowing in the long oval slot at the inlet and the slide will rise and then fall imediately when you stop blowing.

And just how do you propose to blow on that slot?  Reminds me of another topic

You aren't gonna let it go are ya? I just had to check it. So0, we can conclude I am determined, thorough & sometimes very wrong.
I knew when I posted that I was loading the guns that would shoot me. Honestly, the flak has been a LOT less than I thought that post would get. And , all in good fun.
I can laugh at myself.
I was straightening the vent near the wipers on a Ford Pickup with a hook, both elbows on the fender, biceps straining to lift that bent vent just a hair, when it popped loose. The tubular handle hit me between the eyes so hard I knocked myself all the way across the next bay backwards, trying to not fall on my butt. No One saw it, so I had to go tell the guys. That was too funny to keep to myself.

You guys are just making my whole day.

Naw, just rounded out the heads.

But really, it actually went part way up my cheek.  Cool huh?

Anyone can knock themselves in the head.  I take it to a new level
