carb

My engine is running a little lean on my 1979 ct70 and I am struggling to find the air screw (if I even have one)? I realize the screw in the middle of the carb directly below the throttle cable is the idle adjustment screw, but that is the only screw I am seeing that adjusts the carb. Am I...

Hello I have a 72 CT70 with a #60 main jet an #35 pilot, bike was getting hot pretty quick so I adjusted clip on metering rod to lowest level. Rode around block today an bike started to cut out going up small hill. Cylinder head was 168F and front of exhaust was 278F after about 5 min of run...

The jets in my CT seem to keep getting clogged. My bike will run great for weeks then will shut down in the middle of a ride and I will have to get a tow back to the house. Usually I take the carb apart and clean out the jets and the bike seems to run good again. Is this condition something...

I have been trying to get a 1978 CT70 running and have had little success. Last summer the bike would run but only on full choke. So, over the winter I took the carb apart to clean it and replace gaskets that I am sure have not been replaced in a long time...I reinstalled the carb and tried to...

I recently purchased a '78 CT70 that would only run when the choke was fully on. Everytime I turned the choke off, the engine would die. I am no mechanic, but feel like I can usually get these problems fixed. I took the carb off to clean it and make sure the jets looked good. Upon taking the...

Hi everybody, I discovered that the carburettor of my honda ct70 1970 had leaks and so I decided to change it to that of a honda ct70 1972 but I noticed that the covers of the pilots jets were not identical so I wondering if these two carburetors did not have a different throttle cable length...

hey there, Just pulled my K1 out of storage after 5 years. Wouldn't turn over so I cleaned the air filter and carb. Carb looked great with only some crap on the filter. Now that is all back together I tried to start it and it will start with the chock wide open but if I do the bike goes to...

I have an '83 Honda Z50R that was given to my brother by a friend who has since passed away, so I don't have any previous history on modifications, etc. I "think" it is a genuine Honda Z50R ... it has this label: However, it has a "Sheng Wey" carburetor which I understand is not original: I...

I have a 1973 Honda ST90 and have two issues. Problem #1: I have completely rebuilt/restored this bike. I did a complete teardown of the Carb, cleaned it, put it back together and set it to the factory adjustment settings. The bike will not idle. It either races too high and I have to hit the...

Hey Guys, New to the site, and have really enjoyed the 2 weeks of reading all the useful info. Today I decided to post a question I cant seem to find an answer to. just bought a 1979 Z50, and was told it needs a carb cleaning. so I soak it and run wire through every port (the smaller jet...

The needle clip stopper. The one preventing the needle from popping inside the slider. Put new throttle cable, lost this thing. Made one from tin and another one from plastic to the same result: engine now is flooded with fuel on high rev, and the plug is black. I am in a remote location...

Im new to this forum and to fixing bikes. I am fixing up a 74 ct70 for my son that was given to us by my father in law. It has sat for many years inside his shop without being run. So far I have changed the oil, restored the fuel tank, replaced wheel bearings, brakes, exhaust, rear tire tube...

Hello CT70'ers, I've been trying to get this '71 CT70 K0 to start for awhile now. I rebuilt the carb. I've got spark. I just rebuilt the throttle and every single time I've tried to start this thing fuel starts leaking out of the overflow. I can't even get it to pop. I've checked the float...

Hello all, i recently posted a concern i have with my 74 Z50 which developed a bogging when the throttle is opened up. It had run fine and i had taken it apart to replace the kick shaft and since it does not want to run past idle. I posted and the responses sugested it may be timing related so I...

I recently replaced my kick shaft so had the cases split on my 74 z50ak5.everything went back together fine and it starts first kick and idles fine but when I open the throttle it bogs. I have tried adjusting the carb settings and made sure the timing was right on IE cam gear marks and flywheel...

I have a 1979 Honda ct70 and I just purchased a new OEM carb for it from Dr.Atv, and just had a couple of questions about it. Check the picture. I put the question in the picture with labels.

Up for sale is a carb setup that came off of my 1972 HK1. It was used for about a year and a half so far. I am selling it because I am upgrading to an 88cc bore kit that requires a new assembly. I would like to get about $110 obo for it. The carb and the air filter were bought new from the...

Hello, I have a 1973 CT70 K2 and it is come to the time when the engine needs a whole bunch of work after a couple years of hard riding. After spending 100$ last year on a dumb valve adjustment,:102: I am looking to end all problems for years to come. It needs: -Kickshaft Replacement...

New to bikes, but I've been a gearhead all my life and worked on all kinds of cars and trucks. My son and I have been rebuilding this bike for him which was handed down by my dad (before my son was even born!... long story). Anyway, we have it running but I still have a couple of things that...
