Daluvian Posted November 6, 2021 Share Posted November 6, 2021 I’m rebuilding some carbs Round tops. The rebuild kit I bought came with n54 and m43 needles, I can’t find any info on the m43 needle, going on l28 stock engine. Any suggestions what needle I should run? The m43 is shorter then the n54.
