Good to hear you got it going good.
Now you will feel more confident in flogging the engine.
Just some info about that engine/carb on the L-head twins.
This issue will most likely happen later, quite common.
If the engine starts acting like carb is going bad, maybe idle gets erratic, throttle response little rough, engine running rough.
Let the engine cool (because gas will fall onto the hot muffler area under the carb and remove the bowl drain plug and just drain the carb bowl. Watch and don't loose the little thin sealing washer on the bowl bolt, re-install the bolt just snug. Water is trapped in the bottom of the bowl and is coming from a contaminated fuel tank usually and little bit of HEET or equal added to the fuel tank will sometimes cure such for awhile. It only takes small smigen in the carb bowl for an upset. Some of them lawn tractors have a large plastic gas cap and the center of the cap is recessed somewhat and when subjected to water it just stands in the top of the cap and will eventually seep past the cap vent or come from your gas can.
If any moisture ever gets accumulated in the bowl on those type carbs it just stays and for some reason just keeps getting worse but draining will sometimes cure all. Only takes couple minutes and about 75% of time will cure all without removing the carb.
I also keep a eye and ear open for old carbs to repair as spares.
But every once in awhile I run into one of them carbs that just won't repair, usually won't idle smooth. I suspect they have had water inside and probably froze and upset the inside passages. (spare carb is a good thing on those engines)
