Hey i never said "cranking" i have done it like your supposed to with adjustments in increments between 1/16 and 1/8 turns and if i set my gap to 0.5 it wouldn't run longer than literally half a second after i backed off the throttle. If your engine runs smoothly and reliably at 0.5 i think you have a carb air leak. Before i sealed my carb on my plane engine i could have the throttle /butterfly plate closed completely all the way and the engine would keep running. Now if it is me screwing up the needles as you say, I can see it as possible if the carb on my engine is one those extremely touchy ones where if you adjust one needle, you have to adjust the other. I was running it yesterday and it actually ran decent but it still wouldn't idle for more than 10 seconds or so and as i was tuning it, i was richening the high speed needle and every time i did it would die quicker at idle until i leaned the low speed needle but yet the low speed did not exhibit any signs of being too rich. Maybe a lil extra smoke but not significant. and i have spent equally as much time on forums looking at how to tune it. Tried to take it to hobbytown to have them try to tune it a couple times but everytime i show up, the guy who does it isn't there and i live 60 miles from hobbytown which is the closest hobbyshop i can get to

The bottle doesn't say the oil content but lots of other people use the same torco fuel without issue. Bought it off Amazon. The crap I bought from hobbytown made my car run even worse
