[TR] Tr6 carbs on tr4

[Greg Lemon]

I have done the opposite, I have TR4 carbs on my TR250.  I had to play with the linkage a bit but other than that it was a bolt on and go operation.  My brother has TR4, carbs on his TR7, he ust bolted them on and they work fine.  I realize these aren't the same swaps, but they show that the carbs all operate within the same general parameters and are interchangeable.

Subject: [TR] Tr6 carbs on tr4


Hi all, I have a 63 tr4 (87mm pistons) with strombergs that have oblong wear in the throttle shaft holes. I'm also got a newly rebuilt pair of Tr6 carbs. I thought I might try those as the tr4 carb does not have replaceable bushings at this time.

I can install the Tr6 carbs, but does anyone know if I need different needles or any other issues I might encounter?
