ummm..I think that one you have freaky is the push/pull job but yeah,
so far as I know it's the same deal except the cable. I have the same style carb ('77 TS400) on my '69 TS250 and it works ok. The TS50 arrived last Sunday as you probably guessed. The frame was cactus underneath (fixable) hence I slipped the motor out and fitted it into the TS75 chassis. Pop off the head, check the bore, no probs, back on with the head, clean the carb, rip out the old airfilter, fresh fuel, connect some wires, 3rd kick and it started and went straight to idle! absolutely minimal engine noise and purrs like a kitty
1st kick now no choke and she's away everytime.. a bloody little ripper
The TS50 roller I'll repair for a another project. Anyway, consider the carb sold
thanks freaky
