Ed the rookie needs help

[Ed]

Thanks Guys, I feel a little more educated. I fabricated my test jig for my McCoy .35 and .40 I tried to bench test them and failed miserably, Maybe this ˝ A guy is just not ready to graduate. Here’s what happened, I connected a Sullivan 1 oz. tank vented  primed it though the exhaust port good glow so I started cranking, no chicken stick or electric starter, just my finger!!. The .40 not a sound, the .35 lots of pops never ran. Only popped when primed I never saw any fuel flow in the line from the tank to the motor??. I would gladly ship it to some good hearted soul to bench test for me then give me instructions on what the heck to do. Sorry for being such an idiot.

Lets try this again. Take your engine and mount it to the stand. Screw the needle out 4,5 turns. Put your finger of the venturi and pull through 3 times. Flip once and connect the battery. Flip briskly. Should start if the fuel is good and the plug is good and you have compression. Good luck

Ed,
The experts will jump in I am sure, but my experence is that the McCoys like to start wet!
Close the needle then open up 3-4 turns.
Do like Robert said, WITHOUT the glow starter attached, put your finger over the vent and turn the prop over 4 or 5 times. When you take your finger off the vent, a little fuel should run out. Back flip one or two turns. This sucks the fuel in. Now attach your glow starter, now turn the prop over real slow. You should feel a bump. Now it is ready to start flipping.
It should at least fire. If it runs and quites, open up the needle a half turn and flip again.
Keep going until it runs.
If it quits when you take your glow starter off, then the plug is bad.

Things to keep in mind.
Your problem is either fire, or fuel. Fire is the plug, fuel, too much or not enough. Make sure you tank it mounted with the center line lined up with the vent. Just like on a plane.
I would not use a electric starter as it could damage the engine if you grind on it a lot.

I am no expert, and not the engine expert. But this has helped me.

Make sure the needle valve assy. are not plugged up. Just another thought.

When feeling for the bump make sure you have a firm grip on the prop. If an APC or other sharp props wear a glove unless you like stitches and amputation.

Thanks everyone; sites like this could rid the world of all ignorance. Mr Storick, I am honored with your reply. One good thing! I'm not having a problem logging in...

  Ed,  If you still cannot get it to start and want to send it to someone to check it out, I will be happy to check the engine(s) out, start them and get a good setting and instructions for you.

  All you will need to do is [ay shipping both ways.  I will charge nothing for my labor.

Thank You So much, Mr. Denny I will try again this week end. If I can't work it out I will surely take you up on your offer. What part of the country are you in?  Ed Vega

The nice thing about the weather tag in your profile is it tells where your at. Just click on the Blue more link in that weather icon of the profile you wish to see where that person is from and it opens a new window with city,state and weather.

A cheap leather glove on your starting hand is good insurance.  If and when it pops back on you, it saves a nasty cut.

HI Ed,

IIRC, you said your McCoys are the later Series 21 "Black Head" ones, correct?

If so, they have a "dykes" ring and do need a pretty sharp "flip".  I would still follow Ty's instructions on using a good fuel with at least 50% castor.  Being ringed with help lower the need for "all castor", but it is still a plain bearing engine, and not made of the most "wonderful" metals available.

Hello Ed,

Here is my method for starting an engine on the test stand.

Remove the glow plug, hold the engine in your hand & flip a few times. Hold it in it's side with the exhaust port down & flip a bunch of times. Hold it upside down & flip a bunch of times. Do all of the above until you are sure that there is no fuel left in the engine.

Put it in the test stand. Hook up your battery to the plug & confirm a nice bright glow. If it doesn't glow brightly, change plug or power until it does. Install plug in the engine.

Make sure the tank is not mounted higher than the engine or it will siphon & flood your engine while you are trying to start it.

Open the needle 3 or 4 turns. Put your finger over the venturi flip until you see fuel come up the fuel line & into the engine. If no fuel is being sucked into the venturi, stop & correct the problem. Flip only enough to get fuel to the venturi, stop, don't flip any more, remove finger.

Now peek into the exhaust port & turn the prop until the piston is down. Put two drops of fuel on top pf the piston. Flip flip flip flip a few times. this is to vaporize the fuel. Our engines run on vapor, not liquid.

Hook up power to the plug & flip smartly, be prepared for it to start. 

Hope this helps.
