Decided to rebuild my 2 carbs, Mikuni VM38-3's, 1980 Polaris TX-L Indy... Cleaned them up and the only thing I replaced was the needle valve assembly; new seals and that little spring. Put it all back together and didn't adjust the float level. Started up and idled good, gave it a little throttle and gas was gushing out of the overflow lines. Figured out how to adjust float level, took it all apart, turned the carb upsied down and bent the tang on the float arm until it was parallel to the carb body. Put them back on and it did the same thing! Now, I'm guessing that little spring is givin me trouble. The old ones were almost flat, the new ones were real springy. How do I compensate for that spring tension? Should the tang rest on the needle when the carb is upside down and level? What does the spring do? I may even have it on there completly wrong.:dunno: Big fishin derby this weekend! Need some transportation to weigh-in...thanks in advance for the help.
