SKIPPER1 Posted April 15, 2011 Report Posted April 15, 2011 my 49 ply 3- window business coupe w/ original flat head 6 has been idling very fast after a short drive -1 or2 miles. So I adjusted the idling screw 1/4 or so turn counter-clockwise and the engine idling dropped to an exceptable level. Drove it around the block and it ran an idled good. got up next morning started up (but did not drive it),idled smoothly. BUT, next day went out and she would not start! just sputtered and "coughed" but would not start. Read all related threads on forum on this subject- tried priming carb w/gas and later w/ starter fluid but no start. any suggestions please- Thanks SKIPPER1 Quote
Don Coatney Posted April 15, 2011 Report Posted April 15, 2011 If you read all threads on this subject did you do anything recommended on these threads? Have you pulled the spark plugs and inspected/cleaned them? To me that would be the first step. Do so and report your findings. Quote
SKIPPER1 Posted April 17, 2011 Author Report Posted April 17, 2011 Replaced wiring (16 guage), from starter to auto. choke (w/ new connectors both ends); replaced plugs (Autolite 86, gap .035) Note: old plugs, the first 2; were black and sooty on tips and threads; the other 4--so-so. Chareged battery 2-3 hrs, primed carb w/ little gas, but cranking no start. Maybe, next step a little forced air though fuel jet connecting carb to gas line. Ok Don C., Greg,, or others, any other suggestions for me?? Again, thanks in advance SKIPPER1 Quote
ptwothree Posted May 5, 2011 Report Posted May 5, 2011 Try a shot of starter fluid down the carb. If it trys to start or runs, you have a fuel problem. If not, it's electrical. Quote
1941Rick Posted May 7, 2011 Report Posted May 7, 2011 STAY away from starter fluid....if you want to do ring damage this will do it....dry's out the cylinder walls and pre-ignites. Any job site I went to the first thing I did was get rid of this stuff. Put gas down the carb... Quote

greg g Posted May 31, 2011 Report Posted May 31, 2011 Is your idle screw still present??? I have heard where some folks back them out past the threaded portion and then the spring pushes them out. By the way which screw were you screwing with??? If you are trying to adjust idle speed, that screw is on the throttle linkage portioin of the carb, the idle mixture is in the lower casting of the carburettor near the throttle plate pivot. If your mixture screw is there, screw it in till it stops, then back it out 1 and 1/2 turns, this is the default setting and should be proper for 95% of running conditions. The speed of idle is controlled by the other screw. note this http://www.imperialclub.com/Repair/Lit/Master/010/Page20.htm and read this http://www.imperialclub.com/Repair/Lit/Master/010/Page02.htm Quote
