stallion_explosion Posted August 12, 2013 Share Posted August 12, 2013 i've lost one of the washers off my high speed needle assembly on my mac 28 (the lower one, specifically). any ideas what size washer i need to replace it? I do know that none of the hundreds of washers i have around the place are the right size. Quote Link to comment Share on other sites More sharing options...
stallion_explosion Posted August 12, 2013 Author Share Posted August 12, 2013 it's the smaller diameter of the 2 in this assembly, infact http://www.modelsport.co.uk/ho-bao-.21-main-needle-hub-valve/rc-car-products/27207 Quote Link to comment Share on other sites More sharing options...
Anthoop Posted August 12, 2013 Share Posted August 12, 2013 (edited) The carb. on the Macstar .28 is exactly the same as the Hyper.21...the lower washer on the HSN is 4mm inside diameter and the upper is 5mm.
