I have a '71 Johnson model 125ESL71C 90degree V-Type, 4 cyl, 2cycle. It does not have the original carbs. The ones on it now are number 317470-D2. The low speed jets are non-adjustable fixed jets. The jets are located on the rear side of the upper carb body, just above the float chamber. Where can I get replacement jets of different sizes? The engine runs great at wot, but does not idle very well. Can the fixed jets be replaced with adjustable?<br />Thanks
