G Digger Posted May 14, 2023 Share Posted May 14, 2023 Hi everyone I have just reinstalled a oil pump on my dt after years of premix. It appears to be smoking a lot more. Do I remove a shim or add one to lesson the oil/fuel mix. I’m thinking add so it lessens the stroke of the pump. Am I right or wrong.
