        Thanks so much.. I have sent off for the primer seals.. I will make sure the check valve is not stuck !! great information.. the fogging oil that mumbles recommended didn’t seem to increase the compression so I went ahead and took her apart one of the rings were stuck.. the video you have guided me threw the process of freeing it up.. it was the top piston ring.. will I need to replace the rings or can I use the ones I got? Don’t have a lot of experience in this area so I don’t want to screw up the piston.. any advice would be much appreciated.. thanks

                Hello… I have an LS38, I think like the LS37. I need some very good pictures of the vertical carb control rod, the on with the spring on it. My motor is missing this completely including the little block. I need to find one or make one. Think you may be able to help? Thanks Jim 813 340 5565

                      Thanks so much. I have to make one or find one. Can you give me the exact distance between the two mounting pins? Jim, Clearwater FL.
