Cold Start - Engine Racing

Good Morning Stellaland.

I started up my Margs, this morning for a ride to work. It was a little brisk outside, the coolest I have ridden Margs since I've gotten her.

Keep in mind I rode her all across the Pennsylvania countryside the first two weekends of August going to different rallies. Never had a problem with her. She ran beautifully.

This morning, after she was started up, I rode her a few blocks to the stop sign. Engine revved higher than normal. At about 3000-4000 rpms according to my tach. Difficulty shifting.

Had the same symptoms all the way to work, which is approximately 2 miles from my house.

When pulling in the clutch, I noticed engine revving high. She also didn't shift as smoothly from gear to gear, especially when I was slowing down to a stop.

Any ideas or suggestions?

Sounds like an air leak to me. I would start with the easy things. Retorque the head bolts, make sure the carb is set down and sealed properly. You can spray a little carb cleaner around the carb and it can give you an indication if that is where the leak is.

Give those things a try and let us know. Just be careful riding it. The high rev air leak means it's running very lean so very hot.

Thanks for the reply - will check that out when I have time. The bellow rubber is cracked - does that have any affect? It's been cracked since I got her however never had a problem till now.

The cracked bellows isn't going to make a difference except to possibly allow a little more dust. The air intake is under the seat through the body and into the bellows

As long as your checking the carb I would pull the jets and blast them with carb cleaner. It could be a little blockage.

I haven't had a chance to open her up. ( wife, 3 kids, football, church, job, blah blah) but on a lark I decided to try again and take old Margs out to ride to work. Wouldn't you know it.. no problems.

Something must have been catching or an elf fixed it while I slept.

Nice!

Don't ya hate it when life gets in the way of scooters!

May have been a little piece of garf in one of the jets that worked loose and cleared things up. Might want to at least pull the jets and hit them with some carb cleaner...when you have a chance!

I had this one time and it turned out that the throttle cable had rusted and started to break near the carb. It was an exciting ride that last time before I replaced that cable.
