I have a '54 SC,SN 8038729 that has always been a good starter until this year. I have had issues with damp and wet weather because of carbon core a wires on a magneto ingition. I have good spark at the plugs,they are gas fouled due to flooding from the engine kicking back against compreesion when the starter is disengaged.Compression is good in all cylinders. I have had the carb apart twice,it is clean,thought the issue might be the needle not seating, or a leaking float. The float checks out ok ,did the suck test and the needle is working properly. I was taught that the initial mixture screw adjustments were to seat the screws and back off 1&1/2 to 2 turns to start. I have done this to no avail,played.A little both ways,checked the plug gap,and closed.them up a touch,now have the occasional fire ,but still have flooding when starter disengages, have tried with the fuel completely shut off. Question. There is a raised boss on the bottom off the carb just behind the choke,looking at it from the bottom, it looks to have had a very small expansion plug(frost plug) staked in place , which is missing ,in this areas,there is a very small drilled hole into the throat behind the choke plate,should this be open to none filtered air?I The firing order is 1 3 4 2, what be the normal position of number 1 plug on the mag cap? According to this unit it is at 4 o clock. The oil filter is in the way to pull the cap the check the rotor with number1 on top dead center.Mag has counter clock wise rotation .I thinking some one has change plug wire position on me. What is the proper plug gap? What is the proper mixture screw adjustments, and what sequences? Point gap of mag if the cap has to come off to determine rotor position. Thanks for you help, Dane.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
