Water in Engine

Found a replacement bank of carbs for $75, now I get to break my finely done rack apart, clean and rebuild the one carb I need from the spare rack, hook it up, wet set all over again and reinstall on the bike. Remember kids, brass is soft and doesn't take abuse!

 

Soon you'll be pretty good at it, with all that practice!!! That how WE learned

 

Oh this is killing me! Got the replacement carbs, broke loose the one I need, popped out the brass cap, sprayed cleaner in there to make sure there wasn't any brass swarf to mess up the threads, and the damn mixture screw is bound up on something. And sure enough the goddammed slot head broke up. I am taking this to a machine shop, I am not going to screw up another carb.

 

I know the carb bodies are slightly different, can any of the other ones be swapped in for #3? I have an entire rack, and I would be installing the cleaned internal parts from my original set (throttle shaft & plate, jets, slide, etc.) and I am not opposed to using on of the other ones. This is not the Cali specific carb. I am just too frustrated to go and look at the stupid thing right now.

 

i believe #2 and #3 are identical. they just have different throttle bits.

From looking at it, none are the same, but #1 would be the easiest to adapt as I would only have to drill out the fuel passage on the left side (looking from behind the engine).

 

Things are looking better now. I set these carbs down and walked away for a few days, took care of a few honey-doos, got the flu, got over the flu, got off work early this afternoon and decided on a new tack. Previously, I had tried a spiral style screw extractor which, as I stated, shredded the brass rather than grabbing it. I didn't want to do the same thing to the replacement carb, so I sought out a square-style extractor in the hopes that its corners would grab and turn the brass rather than tear it apart. I'll be dammed if it worked! Took a 1/8" drill bit and put a shallow hole in the top, gently tapped the extractor in and out it came. Snapped the mix screw in half but it was wasted anyway.



So now I finally have an empty spare #3 carb, plus a good hook in case any of the mix screws in the other three carbs (on the spare rack) bind up. Its filthy, but that can be dealt with easily.



Since I went to went much trouble to clean up the internals and hat on the original one, I am planning to just clean this up, break the original rack and swap everything over to this body and install/align into the rack. Probably won't even use this float bowl as I already have the new drain screw in the other one. I will need to replace all four mix screw o-rings just for good measure, and of course re-kajigger the float settings, but hey it's only time, right?

Fact is, considering how well the square tapered extractor worked, I am thinking on getting one the next size up and seeing if it will grab the remains of the mix screw from the original carb. Maybe I can save it, and have a complete spare rack!

 

Good news, plus tips on this are always helpful. Like most folk I've had poor experience with the left-handed spirals so another
option is great.

PS Well impressed by your sustained enthusiasm. The profit of age I believe..

 

Thanks, I have a long history of 3/4 finished projects, and in fact cleared out a few of them prior to beginning on this bike. I promised myself and the Wife that I would make a more concerted effort to see this bike through to the end. I spent a good bit of time at the beginning sorting my tool chests and clearing my workbench as well as a means of keeping me from getting frustrated at the clutter. Unfortunately that plan went awry when I started in on a rebuild project for a gas powered saw. Luckily it's pretty easy to tell the difference between German saw parts and Japanese motorcycle parts.

 

I'm not out of this fight yet, but what with the holidays, vacation time, and needing to rebuild a demolition saw for work this project has been pushed to the back of the workbench until sometime in January. I cleaned up the spare carb and got the mixture screw out, so my next step is to order replacement o-rings for all four mix screws, swap everything over to the replacement carb, probably will buy the proper float measuring tube from Len and double/triple wet-check float levels, then back onto the bike. After that, its wheels/brakes/suspension on the rear end, followed by the same on the front. Should be a springtime rider.
