P125x/177kit


This happened a couple months ago, and again last night:

Rode the scoot during the day, let it sit for 4-5 hours, and when i went to start it, it was more difficult than normal, had a slow, choppy idle, and was putting out a lot of smoke. Any throttle killed it. After a few minutes, i was able to twist the throttle but it sounded bad. Smoke eventually went away, and was ridable.


Any ideas?

I really hope thats it. Im breaking in the 177 kit slowly/carefully, and really don't need any major problems.

I pulled/cleaned the plug just now, and turned the engine over by hand. Nice and smooth. Looked down the sparkplug hole and it was a little wet in there. There were a couple timew when trying to kickstart it lastnight, that the kicker really didnt want to move.

Two easy things to try:
Turn off the fuel tap and let it run for around 30 seconds before killing it.
That'll give you some needle/seat leak room in the fuel bowl.

Turn off the fuel and let it run till it dies. If it doesn't rev up a bit and die the fuel tap isn't working.

Thank you.

Now that I think of it, I was adjusting the throttle cable, and working the slide by hand previously. Maybe the tap was open and i was just dumping in fuel...

these carbs don't have an accelerator pump. any additional fuel from throttle action was leaking from an already bad seat/needle/float or a bad tap

I agree with gick. it just sounds like it was flooded.

have you done seals yet? also, remind us again what't the carb/exhaust set up? are you running premix or injection?

Everything started up and ran fine today.

26.26/Road2/malossi 177/injection, but putting a little extra oil in the fuel during the break-in of the 177.

don't do that. If you want it richer, then increase the jet size.
