Dang it box car, I just lost an hour going throught that site.
Lots of good ideas and products from the other side of the pond. Check out the fuel tank setup.

I've been interested in a RCGF 15cc gasser engine, but the weight is a little much for it's hosepower.

Would converting this engine to Gas/Glow be viable. Removing the EI would remove 8 oz including the equipment and battery. This would ge the engine down to about the right weight and a little increase in power would be icing on the cake. It looks like possibly the best of both worlds with a simpler operation and cheap fuel.

I'm looking for a gasser to replace .61 glow that weighs in at 25oz and is close to comparable in power.

Any comments appreciated.

Well, I would say it is definitely worth a try.... I have used Gas/Glow on everything from converted Super Tiger .90 engines up to and including a 50cc Echo twin. Poulans, Homelites, Ryobis, Stihls... Give it a shot and let us know how it works.

Well Bob!!!! I don't see why it shouldn't work if it works on weed eaters imagine how it would work with the timing an power that these chinese engines have, I sell the RCGF line of engines but I havent tried one with gas glow, but I know this for sure even the gassers with CDI benefit in horsepower increase with the Gas/Glow fuel and CDI combo.

Anyone, need a good source for the glow plug adapter for CM-6 (10 mm) plug to glow plug. I cannot find it in the Horizon Hobby web site.

I've seen it somewhere in this sthread, but now can't find it.

Many Thanks

i need a few 10mm cm-6 plug adapters that use gasket type not the kind that have tapered seats where they screw onto the cyl. head. i can make some out of some old gasket type spark plugs, but i'd rather ones already made. Cajun1 try C&H ign. Agape engs and ign. on the web.

I have some made out of standard 14mm plugs, if I had a junk 10mm plug to modify in my lathe I would make you an adapter...

I think www.ch-ignitions.com has them.

i looked there and i need to call them to see if indeed they are the gasket kind. thanx av8tor1977.

thanx rangerfredbob for the offer. how do you make them?????? using a 14mm gasket type spark plug???? and what do you use to fill up the hole with and then tap to 10mm??????

The problem with the adapters for the perfectionist is that they tend to recess the plug or hide it up in the plug hole for the reach is not as long on the glow plug.

They will probably talk to you about this at CH?

I get used tapered plugs from work for free (out of chevy 350's generally), cut off the hex part on the lathe which lets the ceramic part fall out easy, I leave some of the flat part behind the hex so I can grab it when I flip it around, next I cut off all but about 3 threads with the lathe and now tap to the 10mm threads (they are just the right size to tap without drilling, then flip it around again and clamp onto the threads with the chuck (it doesn't take much, and I do it with the intent of leaving it in the engine so it works fine) and trim off the other side right up to the taper, this makes the most compact 14mm to 10mm plug adapter you can get. If I'm going for a glow plug adapter I follow the same steps shy of tapping with the addition of making a plug to go in from the combustion chamber side out of aluminum that's a press fit, tapped to 1/4-32, before pressing in I put a dab of green loctite (sleeve retainer).

So far I have not found a 10MM glo plug adapter. Lots of 14MM but no 10MM.

Any other suggestions.

Thanks

best bet would be to make one or have someone do it for you.

Are you talking 10mm sparkplug or 10mm glowplug? I can't imagine how to get a glow plug to set into a 10mm plug hole, as even 14mm is tight. You could get a glow plug to set flush at the top, but not down inside the plug hole.
I bought an adapter and other parts from these guys.

I don't think there would be enough meat in a 10mm X 1/4"-32 adapter for it to be very reliable?

yeah, glow plug is going to be somewhat high on that setup I would imagine.

Apparently these were available commercially at one time, but I suspect they were for 14MM plugs, as they are still available. No one I've found has the 10MM X 1/4-32.

As referred to in post 265, these guys have 14 mm to 10 mm and 14 mm to 1/4-32, but not 10 mm to 1/4-32. For $10.00 each.

Question: Does amyone make a 10 mm glow plug?

The small RCGF engines use the CM-6 plug which is a 10MM.

cajun1 pm me i have some info for you.

spaceworm, pm me i have some info for you!

av8tor1977 help LOL

(without reading the whole thread/ Im just going to ask), my friend has an older Super Tiger 23cc or 25cc (not sure what cc),,

and it has a Glow Type Barrel Carburetor, will the Gas/Glow Mix work with this type Carburetor ????? he/it has never had a problem pulling fuel to the Carburetor..

thanks !!!!

Jim

Two problems... The carb might work, but be a bit sensitive to adjust. The big problem is that the Gas/Glow fuel mix does not have enough oil for the Super Tiger engines unless they have been modified with a roller rod bearing and a hardened crank pin. If you add more oil, all the percentages of methanol and nitro will be off, and you will be creating a whole new experiment that may or may not work well.

C&H is closed forever.
I do have some 10MMX1/4x32 adapters left over have about a dozen of them.$5.00 each plus $3.50 P&H .Just send me a check and number you want plus P&H.
I do not have gaskets for the 10MM side.You can use a gasket from a 10MM CM-6 spark plug,hard to get off.
