Reviving a 200x. Many Questions

[jmcgill]

I just got my hands on a 1985 200x that has been sitting in a barn since the early 1990's (and boy does it look like it). After brushing some of the crap and dust off of it, I have had some time to make an appraisal. It is complete aside from the muffler, which is a nice thing, the tank doesn't have any holes in it, and seems to be rust free inside. The motor turns over and has compression, the kick start works fine, and the transmission shifts to neutral and at least first. All the plastic is in great shape and the seat is good.

So, I started to tear into it and the first thing I did was take the carb off....it was varnished pretty well, so I cleaned it up and got it free and moving with carb cleaner. I put it back on and attempted to get it to fire, so I could see if there was anything wrong with the motor, in terms of the valves, and so forth. Unfortunately, I can't get it to start for the life of me. I have spark...I tested it by touching the plug to the fins while I cranked. Best I can do is to get it to pop a few times when it's choked. The air filter is gone from the original box...so I don't know how that would affect the starting of the motor.

It seems like it's flooding pretty badly....after about 10 kicks, I can take the plug out and it's soaking wet with gas.

Any ideas on how I can get this thing running?

Thanks,

Joe

Did you clean both jets while the carb was apart ?

[jmcgill]

I had the whole carb apart, all the screws out. I know I cleaned the main jet. Where was the other one?

unfortunatley when a carb has been sitting for a while it can cause alot of problems with your jets and the carb is just completely ruined.You will probably have to get a rebuild kit but even that might not fix the problem due to varish build up on the carb walls. Just try cleaning it completely including all jets soaking in carb cleaner. or if you want my opinion ,I would just buy a new carb to fit your model.

Yes thier is a small jet next to the main jet . will need a small flat head screwdriver to get it out . just clean it up and put a new spark plug and I bet it will run great .

[jmcgill]

I did have that jet out and I cleaned it up. I didn't mess with the pilot screw....so I guess I should go back to the drawing board with the carb first. I'll make sure that the valves are somewhat adjusted tomorrow as well.

I'm going to have to make a parts order on it anyway about it. It needs a new master cylinder for the front brake and that muffler. Also, the rear shock is REALLY spongy.

one other thing, I pulled a mint low hour , like new 1986 200sx from a garage. It had been sitting in there since 1988! It had a carmalized carb to. I had to replace the main jet. I cleaned the main jet thinking it would be fine but it seems that jet is very sensitive. I WOULD NOT IDLE RIGHT AT ALL. I replaced it with a new one and it purred like a kitten. The slightest scarring on those jets will cause problems, the varnish ruined that jet. Like i said this was a mint 1988 200sx with only one day of riding on it! It just sat for 20 years and always garage kept.

Read this before you clean the carb again.

don't try to start it without an air filter!!!!

[jmcgill]

Well, I can't get to a Honda shop anytime soon, and my air filter literally dissolved in my hands. Is there a quick substitute for it? Also, I just had the carb off again, and cleaned ALL the jets. Put it back on and same thing....sputter, sputter, die. If I try to give it some throttle while kicking, it is REALLY hard to kick and won't even attempt to fire.

i recommend a rebuild kit from ebay. they run about $20 shipped and provide all new jets and screws!!! all you really need is your slide, spring, housings and float.

[jmcgill]

How many 'orings" are on one of these 200x carbs? When I took it apart, there were none. I'm guessing one or more of them had disintegrated over time. My 200x manual only shows one 'oring' on the pilot screw.

[jmcgill]

I guess I'm going to have to overhaul the carb completely.....or buy another one. It's flooding VERY badly...so badly that it's shooting gas out the exhaust. I'm guessing that's the carburetor not being right because it has spark and compression. I've never seen a 4 stroke motor flood this badly.

[oscarmayer]

yea the carb is shot. you need a rebuilt kit minimum.
there's the oring on the pilot screw, the one on the bowl, the one on the bowl drain screw, the one on the lower jet access screw on the bottom and i think 1 more.

the kit dose not just include the orings it also includes new gaskets, new jets, new idel and mixture screws and springs for the screws.

they are well worth the $. if your not sure about rebuiulding it yourself, send it to me and i'll do it for ya and even test it to ensure it's working properly. (you will still need to adjust to your engine but i can test it's function.)
