Default US Carburetion snorkel kit REVIEW!

It SUCKS! Installed on a honda 6.5 hp, 3600 rpm, 3kw generator. Hit the primer button, pull rope, generator fires on first stroke and thats it. Adjust gas valve repeat over and over till out of adjustment. Repeat 2 more times. Will only run "poorly" if primer button full pressed, release and she shuts down. Put choke on about 75%, hold primer button, runs good.

Start generator on regular fuel, and start opening gas block adding natural gas to the engine. At some point the engine should start running pooly or stall due to over rich mixture. How ever, at no point, did engine get out of tune.

I believe the snorkel is undersized, not allowing enought fuel to do anything.

I have tried several of those kits... VERY DISSAPOINTED! They seem to want the consumer to do their R&D work for them. The older venturi kits were okay but the snorkel kits are J-U-N-K. in my opinion.

The concept is good. I got full power out of a natural gas JB with a home-made 'snorkle' type of carb mod.

Sounds like snorkel tube may be too small dia to flow enough fuel.

I would expect the snorkels to be sold in various sizes coresponding to various sized engines (CC or hp)

What's the length and diameter of the gas tubing between the snorkel and regulator?

Some (most) demand regulators have a vacuum lock. They will not open until manifold vacuum is supplied to a 1/8" port on the regulator. Could be problem #1. 2nd if the unit was too small, it would function at reduced power, not give a no run condition. If it was too large, it might not run.
I would look at the demand regulator 1st, as it seams not to be supplying the fuel, as you say it runs good with the primer pushed in (overrides the vacuum lock)

To me, the "Motor Snorkel", by installing it into the inlet of the carburetor would cut down the total amount of volume the carburetor will pass through it.
I have a new complete CCK conversion kit in the classifieds.

No van lock, 1/8 ports are to be left open. #2, i have no run, due to lack of fuel.

try supplying vacuum to the 1/8 port, it is possible they supplied you with a demand reg that still has the vacuum lock (you can use a hand vacuum pump for this test). No fuel does not indicate too small a mixer, it indicates no signal to the demand reg or some other reason for the demand reg to not supply fuel.

If the OP has a Garretson KN regulator, DO NOT apply 'vacuum' to that port. The KN does not have a vacuum lock-off.

Again, what diameter and length tubing did you use?

1/4" tubing? YIKES!, that's at least part of the problem...

FYI - here's the 'snorkel' I made for a JB. I used 3/8" copper tubing.

I installed a Snorkel kit on my 1982 Lincoln Weldpower 150 with a Kohler 10 HP rope start engine. I hooked up everything but the Snorkel, on a temporary basis for testing purposes. I would not run-period. Since I had spare LP gas parts on hand, I stared at the LP gas tank and replaced one component at a time (LP tank, high pressure regulator, hose from high pressure regulator, demand regulator). When I got to the hose from the demand regulator to the Snorkel, I found that I could blow through the hose in one direction, but in the other it was almost plugged. I found that there was some “Flashing” from the hose molding process that was acting as a check valve. At this point the gas pressure is so low it could not get through. Normally it is a dirt dobber that has plugged the hose. (A dirt dobber can ruin reloading trays in just a few days).

After cleaning out the hose, the welder ran fine with some minor adjustment to the regulator output load block. Since the demand regulator does not have an idle circuit, the engine has to be brought to full speed on starting.

I am in the process of converting some of my other generators to propane. I have test run a Winco/Briggs 5KW on propane with a homemade connection after the air filter with good luck.
