So I was riding and I parked at a gas station and turned the bike off. After a while I had tried to start the bike and it wouldn’t start unless I gave it throttle so I rode it home that night and left it there. The next day I try starting it and it starts for a bit then dies and after a while won’t start again unless I give it some choke. I ended up cleaning the carburetor but it still didn’t fix the problem. It did turn on and run for a couple minutes however. Do I need to clean and rebuild it more thoroughly?
I’ve had it for almost 3 months maybe 2500 miles and I usually wouldn’t need choke to start it up I usually ride around for a while so it’s completely new it not wanting to start without choke it dies whenever I take the choke off after a bit. And no I haven’t replaced the gas cap
No a in-line hasn’t been installed but when I cleaned the carb out I didn’t completely take it apart so I don’t think it’s one of the needles. A screw was stripped so I wasn’t able to open the main part of the carb out. Should I re clean it since I wasn’t able to completely take it all apart?
In order to properly clean the carb you NEED to completely disassembled it. Everything short of that is waisting time and effort. Check YouTube there is a couple of good instructional videos of how to properly do it . Get your self some good tools to. In my experience you need a JIS ( Japanese Industrial Standard) screw driver . Amazon is your friend to get them from. They make life much easier when working with small screws, also old rusted neglected bikes in general. Get some extractors/ easy outs for screws and bolts. They will help you to unscrew the rounded bolts on the carburetors. And in general working on old bikes you will definitely find them necessary more than once. Best way to clean your carburetors is with a Ultrasound cleaner. Second best is to use Berryman Chem-Dip Carburetor cleaner . All the best. Go for it.
An essential tool for removing stuck fasteners is a hand impact screwdriver. If the PO had used one, the heads on those machine screws wouldn't be buggered. Even with Phillips head screwdriver tips, the impact driver gets them out. I replace all the carb Phillips/JIS screws with stainless socket head type, and there's never a problem if they need to be removed later.
I've removed a lot of buggered up screws with Vise Grips. Sometimes helps to flatten two sides of the screw head so the Vise Grips can get a better "bite".
Keepin' all the left over parts. Gonna use 'em to build another bike!
For removing stuck bolts and screws as an alternative to Vise Grips, I use “ Vampliers “. The are little pricey set of 4 will run you about $120 but I have use them in many cases ( I work on semi trucks when I have to) and they are great. Amazon sells them. They come in different sizes , the small ones work great on stuck carburetor screws.
JIS Ball screw driver set.. I own 2, Ball handle very comfortable while applying pressure and torque.. tough driver tips
JIS Hex drive bits, #1 Size #2 Size #3 Size.. whoa boy these have increased in price, $2.69 last year..
you may be able to grind a slot in screw and use flat screwdriver. worst case, grind or file screw head off.. once other 3 screws and bowl removed there will be enough shaft extending to grab with vice grip..
Do Not run a wire through idle/slow jet, there is a micro-screen inside that will be destroyed..
Bucket dip cleaning takes longer (several days) should be agitated from time to time as well as rotated during the soak..
