CARB Numbers?

Postby dizzy » Tue Apr 10, 2012 4:44 pm



Hi everyone, new here and bought a non runner( fires up but won't stay going) 1979 bike.Good compression all cylinders
I need to do the cars but understand that the originals could have been switched over the years. Where on the carbs are the numbers stamped? I'm going to send for rebuild kits but who knows it may not be 1979 model year carbs on the thing and I would have bought the wrong kit.
Hate to tear it down since I have a very short memory having peices laying around for a week or two waiting for parts is not a good idea for me. LOL
Also since I'm more familiar with a distributer cap and rotor I'm not sure how these work without those two items.
I'm guessing the points will spark two cylinders at once even though only one is ready to fire?
How close on static timing must I get the timing is close alright or is exact needed?
Thanks :?

Thank you I read them and its good stuff sure will help. Maybe I'll order a carb kit from Raddak since there are no jets included the year doesn't seem to matter. I may try the split timing instruction today.
Has anyone bought his carb rebuild DVD and is it the extra expense?

I spoke before I looked I dind't see that page before. I went out to look for the numbers and with my eyes I will have to take them off to see it. Hopefully as the article talks about they will be the correct one's. Thanks again

I have not bought the dvd from Randakk,( I am a mechanic by trade) But I doubt you will find anyone who speaks poorly about Randell Washington or his produts. Top notch guy and products ! you can go cheaper but you won't go wrong using his stuff.

I rebuild carbs for these bikes and will not use anything other than Randakk's kits. The man's attention to detail is second to none. I have had the pleasure of meeting him personally and also worked with him to produce one of the parts we both supply.

After just doing a rebuild on a set for the first time, if your not real familiar working with cycle carbs, the video should make the task easier as there is ALOT of ports to make sure they are clean and lots of jets. The guys that I've heard that have bought it are happy with it.

I have the Raddakk kit on order, also from Serius a vacume guage so we'll see how it goes.
I can't seem to get number one & two points timed I have it retarded as much as the plate will go and still the spark is too far advanced.
Maybe I'm not seeing something right don't know, 3 & 4 seem fine.
If when I do it again it still comes out that way maybe the belt is off a tooth

Randakk is great. When I re-built mine I remember there were a few things that I wish he got closer shot of...but it is worth the expense!!!

Ive been putting it off but yesterday removed the carbs and thankfully they were all stamped the 771A
The DVD is fantastic I would never have picked up all of that by reading, so far Ive only watched half of it and its step by step intense.
Almost better than having a guy who ownes the carb shop train you HA!
I bought from EBAY the crome trim that holds the carbs togeather they were missing,I seen on the film it holds them togeather so you don't have to mess with throtle connections and springs. Hopefully today I get to see whats inside if I find some screws to mount the crome trim.

The screws are regular metric hardware store stuff. Stainless is nice if you can. You do know about cross screwdrivers, yes? The JIS standard is cross, SAE is Phillips. A Phillips kind of works in a cross screw, but may strip as the Phillips has internal radii that prevent a good bite in a cross screw. A cross screwdriver set is a good investment for old Honda's.

Good point Fred, but know that the JIS standard is not the same as your common or garden Posidrive cross point screwdrivers. While these will work most times if the driver is tapped into the screwhead, a set of correct JIS drivers is a good investment. Not always easy to get hold of though.
You can tell a JIS screw by the small dot in one corner of the cross.

I never heard of Cross screwdrivers thats really good to know, I'll check at Ace Hardware today I need to pick up a small metric machinist pocket ruler.
Some screws I need to look for are all the screws on my points plate and plate timeing screws they are all banged up on the heads.
Also not sure about the enginering but I would have hoped that one screw was a pivot point and the other allowed movement of the points and timing plate but it seems both screws ( on each point and on the inside timing plate) allow too much movement. I had to time and point gap with everything shifting from all axis, very difficult to get fixed onto the correct spot. Maybe I have wear on my plate too?

Not an expert about point plates, but if it could be machined correctly that pivot would work well. Now I think the both need to move to allow the plate to center on the Rotor so both have the same exact travel.

work update and a plea for ideas!
Did the randak system on my carbs don't have some of the test equiptment like the plugs so I went on faith with leaks. Everything was put back as close as I could get it. One jet in the #1 outside elbow was a 120 instead of a 130 if I remember correctly but all else well.
the right side cyls 1 & 3 are running very lean maybe not firing much at all. I checked the leads back to the coils and each goes to differnt coils.
So what would make one side run lean and the other ok?
Ive removed the vacume check point screws while running taking them out of the right side doesn't make much differance, taking them out of cyl's 2 & 4 stalls the engine.I would love to get it running correctly so I can go on to fixing its other problems lol
HELP MR. WIZARDS!

You can go to autozone to get a vacuum guage under their tool loan program. Just pay the $55 and they give you $55 back when u return it.

Are you sure the float levels are set right?

I din't think of borrowing thats a good idea I bought a set now feel like I could have saved that money.
I'm not a rocket engineer so I won't put my life on the floats being correct but fairly confident they are they aren't perfectly square untwisted and such but fair.
Worse comes to worse I will tear them down again but sure hate to do that.
was just checking and that side gets good spark. Timing should be close but then again i'm no expert there.
My hand held by the exhust the one side hasn't mush of any hot exhust gases coming out

Just remember that you cannot figure out the carbs unless the ignition is perfect.

today I went over the valve adjustments again neeed a little tightening and checked timing still no change.
Runs and starts badly will not idle I have to keep it going at least 2000 RPM's and the right side is not doing much work.
Things I have noticed first the fuel pump while pumping into a device seems to work but putting a finger over the end of the hose I can't feel much pressure I can see bubbles from it backing up into the clear plastic fuel filter the weep hole under the pump has some air coming out.
Second if I spray a flamable like brake cleaner or WD40 around the carbs while engine running I can find vacume leaks on the throttle shafts.
Vacume leaks would lean it out but both sides leak while one side isn't firing much at all?
Also have a new air filter coming hopefully I can eliminate any problems from there, I understand that there is suppose to be some air blockage by the filter causing a partial vacume??????

I keep hearing about finding leaks around the throttle shafts.

Go here and be prepared to be shocked out of that worry.

Thank you for the research and documentation OldFoggy. Nicely done.

Sounds like you perhaps have a fuel issue as that does not sound like enough pressure to overcome the four floats at the same time. Next, sounds like your idle circuit may be blocked on one or more carb. Are you doing the timing statically or dynamically? Static seems to work pretty darn well alone.

Old Fogey Thank you thats really good news the leak is designed in.
I wondered how I would rememdy that situation and now my worry is gone, Love IT!

Thanks Fred I think I will narrow it down to the fuel pump for a test at least.
I was thinking maybe a sqeeze bottle of gas up high to feed the carbs a way to see if I get the same problem. If I had an electric pump I would use that but no sense buying one unless they are a cheaper alternative to a new stock pump. I hate to buy used since there must be diaphrams inside that get old.
I did static timing its pretty close right now but after setting the main plate for 1 & 2 the 3& 4 smaller plate had to go all the way to the stop to get it. Seems extreem not being in a more middle position.
Also maybe and maybe not because of my eyes I may have the left bank off by one tooth on the timing belt.
Its just hard to be sure one way or the other because lining up match marks when there is a gap existing between them
