Mounting the Cline is a lot easier than it looks. Very simple.

You already have the backplate of the engine tapped. You need to run a fuel line from the backplate up to the vent line in your tank. But, before you hook it up--Cline gives you a 1-way check valve to use. You take that check valve and stuff it up in the line about 3/4" and then you stick the line on the nipple you have mounted in the backplate. You want the check valve mounted as close to the engine as humanly possible. 1" or less.

Now that will take the crankcase pulses and presasurize the tank. The check valve will prevent the pressure from coming back out. So, now you got a pressurized tank. I use DuBro tanks and have never had one split out. If you want a bulletproof tank--get a Kavan. I've had a Sullivan slant tank blow it's guts all over the inside of a plane just from muffler pressure. I don't use those anymore.

Okay---pressurized tank. Mount the Cline regulator on about 1" of fuel tubing and plug it into the inlet nipple on the carb. I've done more than a few Clines (about a dozen) and I think it works better if you DON'T use a remote needle valve. Leave the needle on the carb and plug the Cline right into the fuel inlet nipple on the carb. The Cline should be 1" or less from your needle valve.

Now the other side of the Cline gets plumbed to the clunk on the tank.

You will installt a T fitting in both the pressure line and the clunk line. Run a short piece of tubing on each of them and mount them so you can get access to them without removing the cowl.

How it works:
The engine pressurizes the tank. That forces fuel up to the Cline and provides constant and positive fuel flow to the Cline at all times. The Cline has a diaphram inside and a couple valves. It senses the vacuum of the carb every time the crankshaft rotates and opens the hole under the carb. It lets in the fuel as the engine demands it. No more--no less.

You hook it up and pressure test the system. Use wire ties or clamps on everything to keep from blowing the lines off.

Start the engine and let it idle for a few seconds to build tank pressure. Rev it slowly to build all the tank pressure it will ever have. You need to do all your tuning with the tank fully pressureized. It won't get fully pressurized untill you rev it up to full power and hold it for a couple seconds.

NOW you can tune it. Run it up to full throttle and adjust it for max RPM. Back it off about 3 or 4 clicks.

Now adjust the low end. Just set your low end for perfection. It should idle for a whole tank without loading up. The Cline will not allow it to flood the engine because if you adjusted it right--it only lets the engine suck in the fuel it needs.

I've actually mounted 2-stroke glow engines upside down with the tank on the CG. Install a Cline, adjust your carb and it will run flawlessly without any on-board glow or fancy hot plugs. They just RUN.

To fuel it:
Take both plugs out of the TEE lines. Plug your pump into the clunk line and fuel it untill the fuel comes out the pressure line. Same as a regular glow setup. Fill through the clunk--it's full when it comes out the tank pressure line.

Plug both lines. Go fly.

When your done flying:
Pull the plug from the pressure line and let all the pressure blow off. You'll know you pulled off the clunk line if it squirts out a bunch of glow fuel. [sm=tongue_smile.gif]

Worth every penny IMO.
