Now we have had this heavy biggy for about 3 years, changed jets as soon as we got it too LPG, but lost nat gas ones. 8 rings, 2 big ones, 4 middle size, 2 small. LPG are -87, -72, -50, big to small rings. Now I ordered jets from this company, 2 x 28, 4 x 27, 2 x 26 and what arrived was 2 x 115, 2 x 113, 4 x 72. Now I ain’t going to fit these 4 off in middle position as I recon something not right there. Am I correct in saying there should be 4 x 113. Thanks.
