How's the fuel line and tap? If they were clogged, it'll start and idle, but if you load it, it'll fuel starve. Also the little filter dohickey in the float bowl.

Carb is all cleaned out with a good flow and I can see the gas coming out of the venturi when I open the throttle.

If you rev it in neutral it will spin up to higher RPMs just like it should, but has no power once you throw it in gear.


Clutch cable over adjusted, clutch plates shot. If it'll rev, then it should run, unless the clutch isn't allowing full power to go to the back wheel. Worth a look...
That's not going anywhere

Thanks for the help everyone. The bike is running like a champ with a stock top end (thanks to the more handsome dolezal brother) and a new reed. I'm not sure which it was and I don't care. The reed didn't look to be sealing right and I could see a visible gap between it and the block when I took it off. I'm also happy the pinasco kit will go to someone who will properly use it rather than just bolt it on as well. A few odds and ends left and this basket case will be all sorted and hopefully bring in some sweet sweet raffle cash.

So the bike is running decent enough around town. It's got a 110 main jet (stock stella with a sito plus and a hot reed) but still feels pretty pokey. Maybe I'm used to 200 cc scooters, but it seems like it'll only do about 50 mph and has no low end power.

It's not bogging at wide open throttle, but I could maybe set it up a little leaner (don't have any jets lower than 110), but here's my question. Someone stuck a 24/24 carb on here which is not stock on a stella correct? The pulley for the slide also seems to hit against the right side of the airbox when pulled forward which also doesn't let the carb open up fully.

I read that a 20/20 is stock on these and is a 24/24 too large for a stella with only slight modifications like this one?

20/20 is stock... it could effect performance. I've been told by a few people that the 24/24 wouldn't be a big gain for my bike, which is essentially the same level of tune. I'd check time to start and try leaning a bit more. My 150 Stella powered Sprint is peppy and tops out around 60.
