You may need to check your ignition system. The local spam can rental was having the same problem and it was traced to a bad mag. Generally if it is getting fuel, air and spark something is going to happen pretty quick. Not to mention that you are damaging your starter with all that cranking... Hope this helps and let us know what happens. Scott Based on the experience of others, I didn't install a primer on my new Superior XP O-320 engine. I use the mixture control to kill the engine, so I understand fuel has to get back to the jets before it will run. However, I'm having to crank for roughly 20 seconds, let the starter cool, then crank again for nearly 20 seconds before it will start. My start sequence is; Master on Fuel pump on for at least 10 seconds Throttle 1/4 open Crank for 5 seconds Pump throttle one time and hold at 1/4 open Continue cranking for 5 more seconds Pump throttle one time and hold at 1/4 open Continue cranking for 5 more seconds Pump throttle one time and hold at 1/4 open Continue cranking for 5 more seconds Stop cranking and let starter cool for 2 minutes Crank for 5 seconds Pump throttle one time and hold at 1/4 open Start playing with throttle to find the "sweet spot" Starts rough until I find the "sweet spot" Idles smoothly and runs up fine after warm For those of you who don't use a primer, do you have any suggestions? I don't know if I'm giving it too much fuel or not enough. I don't smell gas at the air inlet, so I don't think I'm flooding it, but I'm afraid to pump too much at the beginning. Do I need to just let the boost pump run for a while with the throttle at 1/4 open to get fuel to the jets, or is that only going to work when the engine is cranking over? I just remembered, it restarts within a couple of revolutions when I shut it down using the mixture control, so fuel should be reaching the jets fairly quickly on a cold start.

My AFP injected O360A1D started perfectly for several years even though I had installed the wrong Shower of Sparks unit and it wasn't working at all, meaning that it was starting with NO spark retard because the SkyTec starter cranked it so fast that it didn't matter. Then when the battery started to get weak it got very hard to start. Modifying the SOS solved the problem. So, check the ignition system, be sure it's starting on the correct mag and that the impulse is working. Dave > You may need to check your ignition system.

Your point is well taken. Here where I live in Jackson Hole Wy a 0 degree day is about half the year. :-). My theory was to pump the th rottle while cranking the motor. As soon as it starts just use enough th rottle to keep it running.

I agre e with not being to aggressive about  pumping the throttle when

The except ion to this is when you are trying&nb sp;to start a very cold engine
( 0  ;deg or colder). I had problems starting&n bsp;my engine while in Rochester

Two things to consider:
If the result of one pump of thro ttle is liquid and not spray, your
cran king
engine will not pull the liquid ag ainst gravity.

2nd; my method is to  ;pump once and crank immediately before it
condenses.
This allows me to set the&nbs p;throttle to correct position (nearly closed&n bsp;eg
1/8
inch from closed) for cold sta rt.

I agree that multiple pumps will&nbs p;cause excess liquid fuel and is a f ire
hazard, even while cranking. Multiple pu mps is similar to working with
hammers  and pliers when you need wrenches.

Da niel,

I

My past experiences during the sport racing phase of my past life tells me that there is little or no cause for worry about high rev damage to this type of alternator. We ran many of these units at well over 16,000 rpm without ever playing the change pulley game. The potential HP saving was not sufficiently there to recapture and component failure was never an issue. I for one definitely would not have had the larger diameter pulley by choice. This opinion was not requsted, just offered.

Just wondered if anyone had a favorite fuel/food/overnight stop along the route. I plan to take my time and see some of the country along the way. =================================================== Richard- If you are into staying indoors (hotel) I would recommend Worthington, MN (southwest corner of the state). The Holiday Inn is close by and will come pick you up. They have an excellent restaurant inside. Also North Platte, NE was good although the hotels are a little farther away from the airport. If you want to camp, I've stayed at Mitchell, SD before and enjoyed it very much.
