Thanks for the feedback Peter.

Funny you should mention the emulsifier, because I just had the same problem, where the previous repairer ruined the slot.
I cant get it out, so I was going to clean it out best I can in place and then try it. If it doesn't work, I will have to try something else.

Yes, parts can be hard to come by, you might like this one I bought 2 days ago. It had Mary river in it from the Gympie floods. I was hoping for a magneto.





Blade plate was welded onto the boss.
I managed to get, starter internals, carby and linkages, flywheel and key, magneto, muffler and the rest was scrapped.

Good pictures - I like it. If the mower was free you did well. Suzuki spares are rare.

I have been giving the carb a good soak to free up the emulsifier as much as possible so I can get it back together and give it a try. I will let you know how it goes, it just might be ok.

Worst case it turns into a bunch of parts for the next suzuki I find to re-furbish. They are getting fairly rare around Canberra and the South Coast.

Image shows: emulsifier with a 1.5 and 3mm drill bits show the internal sizes of the tube.
Getting one out with a ruined slot, without damaging it is the challenge.

You have 5mm to tap into before reaching the first small holes.

I was thinking of tapping this bolt in. But then what?
I know anything can be fixed if you think about it long enough.



To clean it in place you have a few paths to spray cleaner into. I find a bent nozzle tube helps.

If you put a tap into it you've enlarged the bottom part of the emulsifier, below the lateral holes Mark. I think it would probably give different mixture results after doing that. I also don't think it is very likely that having an internal thread in the emulsifier will help you to screw it out, unless you use a left hand thread with a shoulder in just the right place, so you screw it in until the shoulder bottoms, then keep turning. Likely to work I think, but left hand taps and matching dies (to make the shouldered screw) of obscure sizes might be difficult to come by.

If you are determined to do something, I can make a suggestion of the "end up with something that is better than nothing" type. Can't say I recommend it, because it is crude at best.

If you get hold of a splined-type stud extractor that fits into the bottom of the emulsifier (but cuts spline recesses when it does so), provided you have soaked the carburetor enough to soften the gum thoroughly, you should be able to unscrew the emulsifier by unscrewing the the stud extractor. Then solder the hole where the internal splines have been cut, and re-drill it to the orignial size. (Soldering and re-drilling brass jets is a traditional practice for old-timers like me.) Re-drill any lateral holes that have become soldered up. The only cost involved is for the splined stud extractor, and that should be a permanent tool you have from then on.
