calling carb masters....

[flames]

hi folks,just a quick q regarding my carbs.my bike when i bort it many moons ago was a 350 frame with 250 bottom end and a 350 top end.the pump and worm drive are 350 so that part is fine.my carbs are marked 4L1 00 which i believe are 250 carbs? the bike always ran crisp and very well,so i believe the jetting has been adjusted to suit.but......my bike has been in bits for yrs,i have had several spare parts kicking about,including a couple of sets of differant carbs.now i cant think i have stripped the differing carbs at the same time,but i was young and niaeve once.pulled my carbs today and noticed differances in the bowls,i know the carbed carb bowl is differant inside due to the choke jet,but are they supposed to differ on the outside?

heres a cuple of pics to show what i mean.....



this is the l/h/s carb (choke side).notice the recessed drain screw,and large drain spout.this next pic is of r/h/s carb



notice it has normal drain screw,and a smaller spout.

l/h/s again




and the r/h/s again.





the bike ran fine with these the other week,so i have no reason to think it will cause a problem.but im wandering if i have somehow managed to mix the carb bottoms up?

the spare carbs i had were 28mm aircooled ones.is it possible that i have mixd the bowls up from these? sadly i no longer have them so am unable to check myself.

thanks for any help.

I have two sets of 250 carbs. They are identical. A piccie of one set is below. I'd say one of the bowls is incorrect. However, if the bike runs OK it may not be worth worrying about.

Hi flames, looks like you have a LC carb bowl on the Rhs and a 31K bowl on the Lhs carb. Not sure what the difference internally is if any. If the bikes running fine and the colour of the plugs are ok, then leave it along. Could always change over to two the same the next time you take the carbs off. If it's not broke, then leave it.
