Maxam,

Many thanks for your replies.
I am still not able to get the engine to start. I have checked all the plugs the glo system lights them all, although I had to check them individually. My on board pack and booster pack are both fully charged both are 5000 MA. I took the tank out and checked all the plumbing, everything is ok. I open the needle on the new OS carb 21/2 to 3 turns. Despite numerous attempts with a large electric starter which turns the engine over vigorously I get no start and very little to no unburned fuel coming out of the exhaust. I opened the low end needle on the carb 1/8 turn,I think, to no avail. Since I cannot burn the fuel out of the engine I injected 20 m l of air tool oil thru an upper follower hole. When I turn the engine over by hand following the injection the oil comes out black. The engine feels very smooth when turned over by hand. I am surprised that a lot of unburned fuel is not accumulating in the lower cylinders. I have had no hydro lock. I have to choke the engine hard and turn it over with the starter to get some fuel to run out of the exhaust. Getting at the low end needle adjustment is difficult but I am ready to try anything to get this thing started. Last year it ran well enough to fly and strong enough to loop my 30 pound Stearman from level flight. I am using fuel which I mixed last year half wildcat 15% and half methanol. I am going to try the fuel in another four stroke engine.

I have the impression that I have a problem possibly with the low end needle setting. MY on board glo goes on at idle and off at about 1/3 throttle.
