Actually I can't make any sense out of your argument. English isn't your first language is it?
Have you ever even run a diesel?
An integral Gilbert 11 glow head can very easily be tapped for a standard 1/4" x 32 glowplug.

(Or perhaps you could just read some of my older posts to confirm this.)
Running a diesel, let me see, I have a PAW 19 that is 37 years young and still going strong, a PAW 15 (not as good a runner but its had a hard life), a Taipan Tyro (that I have sent to David Bourke in Sth Australia) for a new contra recently, MP Jet classic from Dave Owen in a Tomboy, MVVS 49 and 40 diesel conversions (the 49 I have purchased from a moderator here), PAW 40 (also Dave Owen) destined for a Freebird control line stunt model, a reworked Marz 2.5 that lives in a Peacemaker, and 2 Sokols (one being breathed upon right now by 'Diesel Diehard' for racing purposes.)
So, yeah you could say that I have run a diesel or two.
How about you mate?
I agree that the Gilbert head could be adapted to use a standard glow plug but have you ever done this? Expect a slight performance loss as the gas flow would be interrupted by the plug recess; this has been well documented by Cox owners over the years (the plug hole on small engines owns a relatively large percentage of the combustion dome) - so why drop power in an already mediocre engine? And if you have to muck with the head then why not go the next step?
And my 'argument' here is simply support for another member of this forum who wishes to gain information about converting this engine to diesel, that and decrying the use of 30% nitro as a test of an engine being worthy of conversion.
For example I have glow engines that would absolutely scream on 30% nitro but would they make good candidates for conversions as they stand?</span></p><p class="MsoNormal"><span lang="EN-US" style="">Well, no. The piston liner seal is too loose, their timing is way too high, their transfer passages are enormous and the cranks, well I doubt they would live long enough to be of much use.</span></p><p class="MsoNormal"><span lang="EN-US" style=""></span></p><p class="MsoNormal"><span lang="EN-US" style="">So how good a test or ‘rule of thumb’ is using a hot fuel in determining a successful candidate for diesel conversion? All it proves is that that particular engine can run that fuel – that’s all!</span></p><p class="MsoNormal"><span lang="EN-US" style=""></span></p><p class="MsoNormal"><span lang="EN-US" style="">But look, this doesn’t help the original poster one iota; his interest is in converting this engine and he came here for help. And another poster asks the same.</span></p><p class="MsoNormal"><span lang="EN-US" style=""></span></p><p class="MsoNormal"><span lang="EN-US" style="">To date I have suggested that he contact A.J Coholic in Canada (he makes one off diesel heads very nicely, and last time I used his services it cost me about $50 AU per head,) and agreed with steve111 about the light construction being suspect for conversion, the rod especially looks like it should be replaced with a more heavy duty item. But if this conversion was to go ahead then Iwould use a milder fuel with a high ether content and larger prop (the ether having a lower calorific value than kerosene and the larger prop needing a lower compression ratio.)
