I'm here! That was a particularly grubby carburettor Dale. It looked as though a very poorly fox had been using it as a toilet. Great job on the rebuild, the ultrasonic treatment did the trick, I'm sure it will fire up now. If memory serves me, the setter is called an atomizer tube in Dell'Orto carburettors. They all have their own terms of reference I suppose. Best wishes, Dean.
This one's nasty, hoping not more to come. But I know how these projects can get out of hand. Worked on some Dellorto's in the past on the old 70's Harley two strokes. Not sure I have an opinion I want to share about them.
@@montana2strokeracer I've had good experiences with Dell'Orto generally, but there's no doubting the quality of the Japanese brands like Mikuni and Keihin.
Hi Mark, actually they don't on these. It's just a slip fit rubber mount, but this one really seams loose. I am sure I will figure out how to modify something to make it work. Thanks for hanging out with me.
That sounds like a good work around. I don't know anything about it, but never too late to learn they say. I am learning new things every day. Kind of fun you know. Hey thanks for the info and hanging out with me.
Hey, so I’m having this issue with my bike, I’ve rebuild the carburetor numerous times now and cleaned numerous times and it’s only running off of the choke. It won’t idle or it won’t take any throttle at all but I’ll run off the choke.
Hey Levi, yes sounds like the same issue.... you're getting too much air. Try putting a o ring on the intake pipe before the carb goes on, then install your cover so it holds the carb tight to the Oring. That is what I did to correct this one. If you haven't yet done so, replace your crankshaft seals. They are 50 years old and not doing the job anymore. Thanks for hanging out in the shop with me. I will be getting back on this machine soon. So, stay tuned.
Thank you, I use simple green pro, it is actually purple. Safe for aluminum, not the case with the green stuff. If they are really gummy, gasoline in a peanut butter jar, suspended in the simple green solution.
Hi, it really depends on your altitude and your other jets, I always set mine in the middle to start and work from there, take spark plug readings to determine if you need to go leaner or richer in your midrange.
Hey David, man I just don't know that much about Kawasaki's. I have heard that the 70/71/72 I think are bigger carbs. Bigger in the fact that they stick out farther which makes the cases wider. Then at some point maybe 73 up the carbs were smaller to try to decrease the width of the engine. You might try contacting Kevin Bergeron, he has a channel by that name and his experience with the smaller Kawasaki's is much greater than mine.
New subscriber, you are quite a skilled cat. The '71 and '72 F7 carbs are the same. The '73 thru '75 carbs are more narrow, less protruding side cover. The rubber carb mount being a loose fit to the carb body is common as the bikes are half century old. I believe one '71 I had the mount was 'thickened' with electrical tape to help secure the carb. I left it alone. Good idea in your opinion? Thanks, Dave.
Thank you for the info on the carbs, I really have limited experience on Kawasaki's. I am learning as I go along, and I sure appreciate any knowledge that comes my way. I did in up finding a NOS intake. I will be getting back on that F7 pretty soon. Thanks again and thanks for spending time with me in the shop.
Hi Dale, do you happen to know the part number for the rubber gasket on the bottom side of the float bowl? It is the rubber gasket that seals around the two overflow nipples.
Hi Gary, it's not assembled currently, not sure when I will get to that point. This bike is currently being restored, just last week I started assembling the frame and wheels (check out that video) I can try to pop it together and send a picture, but I will need your email address to send it to. No way to do it on UA-cam that I know of. dsweger@bresnan.net
Thank you we followed your video but our bike starts and goes to WOT and when we turn the throttle it dies. Any ideas. Could it be float level? We can move slide freely with throttle
Hey Gary, that was the same problem I had. Major air leak where the carb mounts. What I did to fix it was to slide a o-ring over the mount, push the carb on and reinstall the carb cover. Mine would suck so much air without the carb cover because it holds the carb against the o -ring. I showed all this in the video. I did finally find a new mount. But I have not installed it yet.
Hi Dale, another great video. Thank you. Not a carburetor question, but related to fueling the F7. Do you have any recommendations for a fuel cock rebuild kit?
Hi there. No as far as I know there are no replacement parts for those fuel cocks. I did what many folks do, get the one for the Harley Davidson that is a standard manual petcock fits perfect.
Thanks Gary, and thank you for the spec's, that is much better and almost precisely what I set it at as level. I am not impressed with the Clymer manual. I have factory manuals for most of the bikes I work on. Had gotten a factory one for my F5, but not the F7. Got one on the way. Thanks buddy I appreciate it.
@@montana2strokeracer cant wait to see how you find out if the engine is good or needs a tear down. this would be a good instructional video on tell the condition.
@@montana2strokeracer i have had carbs with the white/yellow powder and much of the pot metal eaten away. your carb looked more like oil and cleaned up great thank goodness.
Super helpful video, bonus that it sounds like Hank Hill is explaining how to rebuild this carb
Thanks, buddy, don't know who Hank is.
@@montana2strokeracer haha ever see King of The Hill? Great show, even better character.
Thanks Dale your advise was much appreciated and at this point trying to install the 1975 carb on my 71 and need the larger intake boot to mount.
I enjoyed the video. Just got a 73 F7. Videos like this are very helpful to me. I’ll look for more F7 content. Thanks, Gil
Hi Gil, thank you very much for your kind comment. The F7 will be coming back into the shop very soon for a freshing up.
Great video, so helpful.
Thanks Jack, glad to hear it was useful.

Very nice job. I like the rostrum or overhead camera, something I will try to replicate.
Thanks Carl, I just made an overhead mount out of some square tubing and a couple nuts. Think I sent a pic to Dean. It really works well.
Cross reference if a Mikuni carb is available
great job dale I'm sure thay have a split plastic insert that goes in the carburettor mouth that nips carb up on inlet spigot when u tighten it

On the intake. Last resort you could make a mold of the old part in silicone moldmaker, then degas and pour a new one with soft urethane rubber
That sounds like a good work around. I don't know anything about it, but never too late to learn they say. I am learning new things every day. Kind of fun you know. Hey thanks for the info and hanging out with me.
Great job brother. That is close to the KE 175 Carb. Mine carb just pushes in no hard mount. If I come across it I’ll let you know.
Thanks Cain, I appreciate it.
frank in the shop!
Glad to have you here Frank, hand me the wrench.

Hi Dale, Great videos - entertaining and educating. What do you use in your ultrasonic bath for varnished/gunked carb parts?
Thank you, I use simple green pro, it is actually purple. Safe for aluminum, not the case with the green stuff. If they are really gummy, gasoline in a peanut butter jar, suspended in the simple green solution.
What is the needle clip set to? Mine is having an issue and now its not wanting to run at all.

@@montana2strokeracer ok thank you

I'm sorry I don't, have you tried looking it up on partszilla.com
Can you show me the full assembly with slide and choke

The reason it dies when you turn the throttle is because your adding yet more air, because of the air leak at the manifold mount.

Hi there. No as far as I know there are no replacement parts for those fuel cocks. I did what many folks do, get the one for the Harley Davidson that is a standard manual petcock fits perfect.
@@montana2strokeracer Managed to rebuild the original vacuum fuel cock with some help from a local machine shop. I had a few extra made just in case.
@@IdlingShadowthat's great,some good ole work and perseverance will do the trick everytime. Nice job.
I can smell that from Minnesota! At least it was full of goop as opposed to corroded to hell!
Yes, that is a plus, rather have to dump oil out, that go through what I'm doing to the Yamaha 90 twin.
Great video, I have the official Kawasaki manual for F And G series bikes, The float level is 26.5mm +/- 1mm. if you need more specs, let me know.
Thanks Gary, and thank you for the spec's, that is much better and almost precisely what I set it at as level. I am not impressed with the Clymer manual. I have factory manuals for most of the bikes I work on. Had gotten a factory one for my F5, but not the F7. Got one on the way. Thanks buddy I appreciate it.
bright side better than water and metal eating corrosion.
There was some water, think it was in the crankcase.

Yikes lots of gunk built up in that carb will cause much of the problem. Spraying lots of carb cleaner and air blow it out ..😊
GOOD LORD!!! LOL!!!
First
Right on brother
Vi. Ton
Definitely one of the worst carbs I've EVER seen. Wow.
Yep right up there for sure. Ultrasonic baby.
That looks bad.
Oh, it is bad...
