Hello all I have a few qs, first is on a used but clean.049 motor in my cox car was wondering with a new glow hot plug how many turns out should my needle be? A guy on YouTube shows his is set at closed but doesn't make sense to me because how is fuel suppose to get to motor, also saw guys putting drops of fuel in exhaust port when piston is at bottom dead center.
Second is I'm using a duel alkaline D battery glow clip type ignitor, I see guys with the rc clip on single D battery ones but that doesn't look like it would Hold onto My plug

does any of this make sense to you guys? Please give details and links to good videos or instructions if possible and thanks for your time

On the Baby Bee 3 1/2 turns out should get U started rich! all ways have the piston covering the exhaust port when priming or U may get a fire started (2-3 drops) 2 D cells in line will bee enough to start U for awhile like this one .. https://coxengines.ca/cox-starter-battery-box-with-clip.html The other one U are refering to is more for spark plug type glow plugs.. https://www.amazon.com/dp/B0006O2Z30/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B0006O2Z30&pd_rd_wg=5hbQl&pd_rd_r=S3EZ879FP3SHTJAX4T84&pd_rd_w=NNObq&smid=A1ZHB4F83K0YSQ hope this helps.

Hi GB,

The "sparkplugs" type ignitor you mentioned is designed to fit glow plugs that are installed in a head vs Cox one-piece head and plug.

Check eBay for "Cox Merlin Glow plug" and look at the picture of the 3-pack. You can see a clamp, and 3 replacement plugs. A gasket gets dropped in the cylinder, just like Cox, then the plug gets dropped in, and then the clamp holds it all together. I like the Merlin plugs.

Alternatively, MECOA one is a true conversion head where a screw-in plug and gasket installs from above/outside the head. The head also gets a gasket between the head and cylinder.

There are a couple of other "systems," like the Galbreath type. I own two Charlie's adapters for externally mounted plugs., but haven't used them yet.

I have used the Merlin in place of a Cox low-compression plug. It took two gaskets to tame the high- compression enough to minimize backwards starts. It yields more power than the low-compression plug. I have not done a direct comparison with a Cox high-compression plug.

Personally, I keep both styles of clips on my field box.

Just be careful with the batteries.  Eric may have misled slightly by saying to use "2 D cells in line".  The two batteries need to be in parallel (which I'm sure is what he meant), not "in-line", which indicates in series.  That would cause 3 volts, burning out your glow head. You only want 1.5 volts.

Here is a photo-example of "parallel" vs. "series" connections.

As Rod mentioned; PARALLEL is needed for this application. It doesn't matter how many batteries are connected in parallel. The voltage does not change. The "capacity" increases.
