1 1/8 is not too lean especially if the engine has some time on it...and also if you are not running 30% fuel either. The less nitro you stick in it the leaner the mixture will need to be set to get it correct.

Just becasue they glow doesn't mean its hot enough to start the engine. Especially if the outside temps are cold. This is another issue. You need a juiced up hot plug battery. This si why many people use glow drivers that have a amp meter on them. The plug should take about 2amps...On a normal warm outside day it will start with less but in the winter time sometimes if the temps are low you need to really kick it up. If its flooded too you need to increase the current.

The Radio South Pro Drive is a good little tool. It will supply the needed current and has a meter on it. There is also the RCATS drive does a similar thing.

Then there is always the guy that uses a power panel. This works too. Then you know if the current is getting to the plug. On th Radio South unit is the engine is flooded the glow driver will increase current flow to help burn out the excess fuel and get it to start. This is a nice feature to have.

Remember batteries don't like the cold either...so they won't put out their best juice when its cold. This combined with the fact that the 4 stroke plugs require a little extra boost anyway to get them to light off....I think this could be your issue.

Try your glow driver off a fresh hot charge....I think it will work. Also if you have any kind of remote glow this will add resistance to the setp and the single battery (C cell) types don't have enough power to push the current through all of this...Yet they will still light a single plug to a glow...but it has to be a little hotter to light off the 4 stroke engines.
