71 t350 piot air screw pickle

[DDudley]

gentlemen esteemed wise men of the forum!!!
Im in a pickle. Im ive rebuilt my carbs but the pioot air screws and spring were missing since i forst got the bike...... Stupid!

so my hunt for the screw began i found an outfit that had them but when i got them today their the wrong ones my aparently the ones i recieved are from a 69 t350.
So my question is arent the carbs all the same from 69 to 71 and if not does anybody know of a sorce fore thesescrews and springs of have any? And the carbs on my bike read
ISO t 186 30
is this the stock set up for that year?
Also if i cant return these to the place i gotem does anybody need a nice nbrand shiney new set of spring and screws
Thanks for any help i get i was so disapointed when i relized im still at square one.

69 T350 carbs are numbered 18611.
70-72 T350 carbs are numbered 18630.

The correct pilot air screw & spring are still available from Suzuki. See:

thanks ill try and return these pronto. Thats odd i called the nearest dealership near ware i live and he wgot back a day or two later saying that suzuki no longer carried them prolly just a case of lazyness

The dealership's parts system may not go back far enough.

If that's the case, then just give them the part numbers that you need. That's usually what I do when getting parts from a local dealership.

yeah i hear ya there. Thats the way to do it for sure. So i crossed referenced my part numbers of these screw with the link you gave me and their the same? But the years are different on the exploded views so it deffiently seems like i have the stock carbs for the bike cause they read 18030. The gal from M&M stried tellin me that there shouldnt be a difference between 69-73.....
So i pulled a scew out of another bike i have just to see if it would fit and if there was anymysterious gunk/stuff in there that might have missed in the solvent bath.. I just duno i puzzled
that place sent me 69 screws and that link says 71 and the part number are the same?
also i noticed that there three holes in the bottem on the in bottem of the intake port all lined up in a row wo of wich have been blocked off is this some sort of predetermind settin rendering the screws useless of is it more of its narrowd down ans the screw if a thine tuning adjustment for these. Sorry for the silly questions. im not farmilliar with these carbs but the seem purdy straight forward as long as a guy has the ringht information. Also ill get some picture up over the weekend of what im dealin with caus it will prolly help
anythoughts? thanks again jabcb!

I have an original printed parts manual for the 69 T350. Per it, the air screw is part 13269-15010
Per the online parts manuals, the 69 & 71 T350 has the same air screw.
So you should have the correct air screws.

They did change the air screw setting & the jetting.
Best place to look for the correct air screw setting & the correct jetting for your 71 T350 is the service bulletins.

List of service bulletins: http://www.ozebook.com/compendium/techbuls/index.htm
For 69-70 carbs, see Service Bulletin #11: http://www.ozebook.com/compendium/techb ... 010-14.pdf
For 71-72 carbs see Service Bulletin #6: http://www.ozebook.com/compendium/techb ... %206-9.pdf

Perhaps other members can explain the blocked of intake holes -- I'm not a carb expert.

Though the overall project is goin rather smoothly so far got hung up with a friend s bike and i have to change a head gasket on my truck.
