[replyingto=alleyoop]alleyoop[/replyingto] alleyoopActually the enricher seemed fine. It was the rod on the other side I was pointing to (the tip of the arrow is touching it). I've gone and gotten all new hose that I'll install in a couple of days and post the results. |

Latest attempt...
Turned all the way clockwise (lean), then backed up 2 1/4 turns. High rpm start and immediate stall, 2.5 no start, 2.75, no start, 3 no start.

[replyingto=beldorx]beldorx[/replyingto]The only thing I found that seemed a bit off with the carb was this rod (arrow in pic pointing at it) seemed a bit bent and the tip where it pressed on the other part appeared worn. Attachments:

Sounds like to much fuel, and it is flooding it. Turn the Fuel Ratio Mixture Clockwise, try a full turn and see if that keeps it idling. If you can keep it idling let it warm up and then fine tune the carb to get the HIGHEST IDLE out of the FUEL RATIO MIXTURE SCREW. Alleyoop As stated about, a Full turn clockwise helped a tiny bit, an extra half turn went worse. Re-disassembed the carb, used a bunch of spray carb cleaner, reassembled, with little difference (once the fuel got to the carb bowl from the fuel lines). I'll play with the mixture some more, but may just have to throw parts at it. Suggestions for a next step? |

[replyingto=skuttadawg]skuttadawg[/replyingto]Disassembled the carb again and checked the float valve. Everything there seemed to be fine

Well, I gave it a full clockwise turn and that seemed to keep it a bit longer (maybe an extra 30 seconds?), but stalled again. Waited a couple of days and tried another half turn clockwise, causing low rpm and another stall fairly quickly, maybe 30 seconds total. Maybe too lean now? I don't know much about carbs, but had heard there are two jets, one for initial starting and another for when it warms up? Maybe that second one was clogged (I thought I checked both, but......)?

Kind of new to engine work, but trying to get the 50cc scotter back on the road. It was laid up all winter and initially had some starting issues. Did some general carb cleaning and got the clogged jets cleared with some canned air and carb cleaner. New fuel filter, checked the air filter (ok). So now it starts right up and idles fine for about 40 seconds, then the rpms start dropping off like its starved for fuel or air, and stalls. I can restart, but it's at a lower rpm and dies off quickly. If I leave it a bit, it repeats. Rather than just throwing parts at it, any suggestions? Fuel enricher? CDI? Another clogged jet?

[replyingto=beldorx]beldorx[/replyingto]Well, I think it was all unrelated. After messing with the float in the tank, I think it was rubbing on the wall. Moving fixed that. The RPM gauge needle is bent down a bit and I think it was/it getting stuck on the screw that is around the 2k mark.
So now back to getting the engine running right and not stalling.

I suppose it's worth a try. We'll see if it just fell off or something. If nothing else, removing the front panel will let me trace the whole pathway.

Kind of new to scooters and engines, but obviously I've knocked something lose or misconnected. After the winter, it was really sluggish to start so I charged the battery, replaced the spark plug, and cleaned up the carb, drained and put in fresh fuel, and replaced the fuel filter.
Now it starts ok, I have no power to any of the gauges, but the lights, turn signals, and brake light work fine. I've checked all the visible connectors (near the engine where I was working) but everything there seems fine. I checked the fuse coming off the positive terminal of the battery and that seemed ok (tried the spare one too with no luck). Thoughts on what would take out all three gauges and specifically where to check?
