JB Weld applied on a completely clean surface (acetone works well here) will make essentially a permanent bond.

However, my inclination would be either to cross drill the older carb and bolt it...

RE: Norvel Engine FAQ

Digger -

NV had the .074 plugs a few months back. I expect that these were old stock and have been sold off without any new plugs being manufactured. Since they are now listing the standard...

RE: Norvel Engine FAQ

The idle adjustment screw can be removed - it's a blind hole and it's only function is to serve as an idle stop, so removing it will allow the carb to close more fully. Use your throttle servo trim...

RE: Norvel Engine FAQ

These engines need to come up to operating temperature quickly. Unlike other engine construction, running NORVELs cool will not allow the cylinder to expand enough to reduce the top end pinch and...

RE: Norvel Engine FAQ

1) The prop screw is an M3 x .5mm pitch. Length is around 22mm. The OEM screw was partially threaded. If you purchase a fully threaded capscrew, the spinner and many props will be slightly loose. ...

RE: Norvel Engine FAQ

Sources are the auction site and perhaps finding some tucked away in hobby shops. Monitor theBay for current market pricing. I did see a NIB Big Mig .061 RC go for $102.00 recently, although that...

RE: Norvel Engine FAQ

A few APC props shipped with spacers on a breakoff tree, but most do not.

The best option is to have a spacer turned from aluminum that indexes on the cutout on the front of the APC hub since...

RE: Norvel Engine FAQ

I have not run the NELSON hot plug, but the primary difference between the two is the element composition and element hole size - the hot plug has a larger element hole. Because of the small...

The Galbreath/NELSON is available for the COX .049, NORVEL .049 and NORVEL .061. There is not a corresponding Galbreath head for the .074 .

Your options are an adapter button for long...

RE: Norvel Engine FAQ

Here's a substitution I've been making lately in hopes of keeping my NORVELs up and running. The cylinder screws are quite small, M2 x 6mm, and if broken off flush with the crankcase flange, can be...

RE: Norvel Engine FAQ

NORVEL sold an adapter that allowed the use of a standard plug, but the performance was poor. Many of the folks here use a combination Galbreath head and NELSON plug. In most cases, the engines run...

No -- the cylinder diameters are different. Check out http://www.hypercolor.biz/index.html Tim Wiltse, one of the posters here, makes turboplug heads for the .074

RE: Norvel Engine FAQ

I wouldn't count on SIG having many parts available -- even though they list them on their web page, they likely don't have any in stock. Good luck!!

IMHO, there is none!

Unless, you can run across one in a garage sale where the seller does not have an idea what they're currently bringing.

RE: Norvel Engine FAQ

No -- this is one place the engines differ. The base of the AP carb is round; the base of the NORVEL carb is more of an oblong shape.

RE: Norvel Engine FAQ

Venturi assemblies and carbs will fully interchange between the .049 and .061 engines -- what you have to pay attention to is the older vs. newer style crankcase. The earlier AAN crankcases used a...

Yep! Just make sure all mating parts are absolutely oil free -- a good cleaning with acetone will work well.

You might find a replacement on-line, but parts are pretty scarce now. Since SIG...
