Should the brass screw plug (#29 on the roy ayers site: http://www.ronayers.com/Fiche/TypeID/26/Type/CARBURETOR_(NON-CALIFORNIA_MODEL)/MakeID/4/Make/Yamaha/YearID/28/Year/1987/ModelID/9234/Model/TW_200/GroupID/443465/Group/CARBURETOR_(NON-CALIFORNIA_MODEL ),drain the bowl? Not sure if I am getting fuel to the carb. Not starting, although I think all things are in place. I have good spark. ('87 TW)



Thanks in advance.

Yes, that should drain the bowl. Does it start if you give it a quick shot of starting fluid?

I thought of using spray starting fluid but didn't have any at hand. I was going to ask a friend for some advice and borrow his can.



I am using a funnel through a gas line to fuel the carb. No gas came out the screw plug hole. I did not do a complete breakdown of the carburetor. The bike sat for 10 years with gas 2 quarts gas in the tank and with the gas valve on reserve, but the carb looked clean except for a little thick dark liquid in the bowel. The other parts were clean. I know it doesn't take much to clog a carb, and the best is to do a complete disassemble and replace gaskets, o-rings, etc. I used spray carb cleaner everywhere I could without taking it totally apart, through every orifice. I didn't have an air compressor here.



The gauge shows 3,144 miles, I believe to be accurate by documents and talking to the 2nd owner.



Yamaha said there is no carb kit. I asked earlier in the forum if there was a good place to get one and I looked around the net, but didn't find one. If anyone knows where to buy one, please let me know.



Also, my '87 TW didn't have vent hoses coming from the bottom of the carb. There looks like 2 nipples there. Do both need vent tubes?



Couldn't find a diagram in online manual or ron ayers fiche, with carb and vent hose placement, inner and outer dimensions and lengths. This would be a great help if someone is doing a rebuild and can take the time to take pictures and post them here.



Thanks, john

If the bike has sat for ten years, there really is no option but to remove the carb and do a complete cleaning to be sure everything is clear. Short of that, you will at least have to remove the pilot and main jets and clean them. Also, it sounds like your needle and seat are stuck closed, probably due to dried fuel. Personally, I would bite the bullet, remove the carb and carefully clean it. When something has sat for ten years, it really isn't the time to take short cuts.

Blew thru the gas line to carb and... nada. Clogged. Wish I would have done that before I installed the carb. No worries, I have more time than $$$.
