Hello Andy,

Thank you for your posts, but the site is not up to date, that's why there are issues with pictures and videos.

Answering your question about fuel, we recommend SIG Champion fuel.

Please ask these kind of questions in direct correspondence to us. The forum is reserved for customer-to-customer talks. The venturi is in stock and it is the kind with the bolt like you have. Thank you.

it is 061

What is the number on the crankcase?

You need a venturi assembly, here is a link:

It fits all models. It is currently out of stock, but we should get them soon. Thanks.

The bottom of the head should be flat. Place a graphite gasket on top of the copper one, tighten the head as tight as possible, and tighten three allen screws slightly.

Remove the bolt and using a piece of wood tap slightly on the fuel nipple.

No valve is required - just connect it to the tank.

The head may start leaking if three allen head screws are overtightened, which warps the head. Remove the head, place a fine sand paper on a piece of glass and sand the bottom of the head slightly. Sanding will reveal high and low spots.

Legitimate customers fill out our registration page and provide a paypal verified payment. In your case none of these were done.

We do not ship to dubious customers. The engines are in stock.

OS GGT 15 gasser is no competition - it is too heavy. We would like to make GX 60 and GX 90, but too busy at the moment. Some day...

Part number 101005. It is in the 061 parts section. Here is a link:

Since your engine works fine without the muffler pressure and floods when you connect the muffler to the tank, all you have to do is screw the needle clockwise - the more fuel pressure, the less needle valve opening...

Make sure there is no compression leak through the head - drop some oil on the head and check for bubbles.

Just keep in mind that you will have to re-tune the carburetor again once you switch to a different prop size.

It has been designed, but when the production will start is still unknown - too busy at the moment. But the 60 gasser is high priority.

Hi Mike,

For some reason our emails to you don't go through - AOL blocks them... Anyway, the engines are available, but the manual should be ready within two weeks. We will contact you then. Thank you

All NV needle valves have fine threads. If the fuel leaks through the thread due to high pressure, you can easily fix it. Take a 3 mm diameter silicone tubing, cut 5-7 mm, and put it on the thread. Screw the needle over it , which will squeeze the tubing and make a barrier for the leaks.

All dimensions are the same as the nitro version and they can be viewed in the Support menu on top of the main page.
