New Bike and a Fuel Problem

sandog · 09-11-2019, 11:29 PM

Hi, new member, and new owner of a Bashan Storm 250.
The guy I bought it from had it a bit over a year. He dropped it on his first ride and bent the front brake lever. Seat height was too high for him as he is 5'6" tall. The bike has 150 miles on it. I paid $700 for it.
When I went to look at it, the tires were low, and tank was almost empty. He aired the tires up, and it fired right up and I took it on a test ride. It ran great, accelerated, shifted nice, etc.
When I came back and came to a stop, the engine died.
When I got home, I noticed the choke had been on halfway.

This evening I got off work a bit early, and filled the tank with fresh gas, and did an oil change. I went over all the bolts and found a few loose ones, air filter looked clean as new, saw the rubber battery strap was broken so I rigged up another. Chain tension was good.

I put the choke on halfway and it fired right up, after a minute I raised the choke lever so it was off. When I did that the idle speed jumped way up.
When I went to go for a ride, the engine wouldn't rev with the choke off, and wanted to die. So I rode with the choke half on.
It ran great, I went down a dirt road a couple miles from my house. I got almost all the way back and as I slowed down to turn, the bike died.
It didn't want to start back, but I waited 5-10 minutes it and it started.
Ran good until I turned into my driveway, and when I slowed down to do that it died again. Still doesn't want to run with the choke off.

It has fresh gas in it, I'll check the fuel filter and see if it needs replacing.
Seems it's not getting enough gas, but runs great for a while.
What else ? Carburetor adjustment ? Valves too tight ?
When I pulled the spark plug cap off, I didn't see the little screw on insulator on the top of the plug like I'm used to seeing. I looked up inside the cap and didn't see it in there.
But the spark seems O.K.
Any suggestions ?
