Recently I reported that the bike would shut down when sitting at a light after the tank had been filled to the brim. I had the wrong idea...
I now believe the reason that was happening was because the engine got momentarily hotter while sitting still. Sure enough, while waiting for a train to pass, the engine died. It then continued to die at every stop until reached my destination 10 minutes later. The tank was at half. I had a hunch that the PO set the idle screw based on a cold engine...
...Nope! The idle screw was set to the bare minimum setting. So basically once the automatic choke turned off, the engine tried to idle at basically no RPM.
5-ish turns later and it purrs like a loud cat. No matter how hard I tried I couldn’t get it to die. Additionally, the friction zone on the clutch makes more sense and the engine sounds much less like a lawnmower as well.
Next on my list is to get my fourth smart’s transmission working. I have a week to move out of my storage unit and I’d rather not tow it out! All that’s stopping me is two bolts and the hope that the clutch actuator isn’t trashed.

My guess is that the previous owner had the habit of sitting on the gas a little bit to keep it from idling itself into a stall, in an attempt to “hypermile” the bike.
That’s just my guess, though. The higher the idle RPM, the more fuel it consumes. At least, that is my understanding.

but the real question is.... do you ride your bike barefoot? in the snow? Uphill? both ways?

I tried riding around the neighbourhood in sandals....Noooooooope! No idea how guys manage to shift gears and not burn themselves.

That’s as good of a guess as any. The carb is new, so maybe he forgot to set the idle screw after installing it? As I understand it, he didn’t ride it much after installing the new carb and sold it to me not long later.

I think you have idle screw confused with the idle mixture screw. Idle mixture screw would make sense if the PO had it lean to the point of not idling, but this was just a case of- as MissMercedes said- the PO being an idiot and setting the idle stop while the bike was cold.

one thing to fix: take off the shift lever and try and shim an extra peice of metal between the lever and the shaft it acts one. that liked to strip/slide and then bad shit happens. do it before it slips

Oh god, will do! Is this a Blast-specific problem, or is that something I will want to do to the Rebel, too?
