I have a G62 in a Wildhare Edge that I chose not to cut a hole in the cowl for a velocity stack. However, this makes priming the engine difficult for the first start of the day, about 20 rotations of the prop with the choke closed and the throttle wide open. With a finger over the carb, this engine would prime in 3-5 rotations, but with this installation, you can't get a finger inside the cowl. What do you guys do in a situation like this?

Cut a 1" hole in the cowl and then insert a 1" rubber grommet in the hole. Glue it in with thin CA. Dresses up the hole and keeps it from cracking out.

Stick your finger in there. Or, use a wooden dowel. Cut a 1/2" rubber ball in half and epoxy it to the dowel. Instant choke device.

Or, rig a wire to the choke lever and run it out the bottom of the cowl.

I have a similar problem with my World Models 80" Patty Wagstaff. But, the hole in the bottom of the cowl for cylinder clearence is large enough that I can just bend down on one knee and reach my finger up in there to flip the lever. Choke till she pops and the pull the lever back. It's not the easiest or best way to do it, but my cowl sure looks cool. [sm=shades_smile.gif]

You might set the plane on the ground and then lay down in front of it. Take a look up in there and locate your choke lever. On mine--I push it closed and pull it open. You might could just reach your index finger up in there and access it pretty easy. I just have to get down on one knee and stick a finger in there. Once you do it a dozen times--it becomes second nature and you won't be fumbling around with it.

(did I just say, "Might could" ?) Dumb redneck. [sm=tongue_smile.gif]

Don't know if it still works, but WD40 had a propellant that was flammable..you can put a 1/16 hole in the cowl and give the carb a shot with the choke and throttle open...Might take a few tries to get it going...

Seems to me I've read that soldering that small hole closed on the choke plate will create a better seal and give you what you are looking for. I have the same issue on my Wild Hare Extra by the way and that's what I'm going to try.

It still works!! At least it did about 9 months back when I lit off a jet of WD40 next to my C.O.'s ear in a place where work place safety regulations don't exist

LOL

Working with you must be very exciting Pat.

If you like HEAT

That explains why you are now a private

The folks that make WD-40 removed the propane several years ago, Ralph. I don't know what they are presently using. There were a lot of articles written here on RCU and rec.models.rc.air some years ago about the change.

WD 40 still burns but not like it used too, I didnt realize it was propane though.
