rough

Hey Fellas, I have a rough Powell I picked up a little while back and I'm trying to decide what to do with it. It's pretty rough. The forks seem to work but are banged up, someone welded a scrub brake onto it, and the tilting engine plate has been welded to the frame making it fixed/rigid...

I picked up another DB-30 Doodlebug today. The bike has a bone stock 6.5HP clone installed in it. Unfortunately, it has been sitting some time. At least since last September. Now, clone motor's do not usually gum up too much and run badly, but this bike has a few malfunctions. The gas petcock...

briggs 5.5 flathead is not running very well. Changed the plug but is hard to keep running. Changed the diaphram about 4 months ago. Noticed a lot of black soot in the carb and on the old plug. Sprayed carb cleaner while it is running but still have to rev the engine to keep it going. Had it...

Hey all, I've got a small issue with the enjoyment of my mini. Running my engine on the stand or on asphalt roads or driveway, my mini runs just fine and will run forever at full throttle etc. But when you ride it on gravel roads, in the yard or anything that induces vibration, the engine will...

I drilled out the main jet in my stock clone carb to .035 which is supposed to be a size 89 or 90 jet size. after I installed the jet back in the engine would not run wide open. It was running very rich puffing black smoke and running rough almost like the choke was 1/2 open. The only mods to...
