Yep , that was the reasoning I used for both my 10/98 and 12/118 engines systems , though I did test my TV84 engine ~20 years ago with a single hole and the oxy bottle to see what would happen, she spooled up nicely , but decided in the end that the leafblower was a cheaper option :-) I did consider the leaf blower but how cool is air start I was hopeing to mount a small air tank on the bike but we'll see it would be nice to have a tank and compressor onboard but don't think I'd have space

Hi
Nice little unit :-)
I'll be interested in some more specs once it arrives , Make , Model , etc etc , as theres not a lot of"external" oil pumps available , especially one with a filter mount.
Cheers John

Thanks for that , it looks reasonably easy to mount up , the Subaru pump is getting harder to source so having a second option is good :-)

So I just tested the flame tube with a small leaf blower it worked pretty well winch it got the fuel pressure wright the flame was burning about 5in outside the bottom does this mean my tursurey holes need to be BIGGER??

While I was testing raw diesel was spewing out the bottom untill I dropped fuel pressure this did cause a decent fire knote to self have a fire extinguisher handy around jets lol

If theres flame burning outside the flametube , you are simply supplying too much fuel , reduce the fuel and let the flame retract back inside and up to the Primary Zone , the outlet temp of the flametube needs to correspond to actual engine running temps when conducting an atmospheric test .
If you have the correct distribution of holes , both size and position , then don't change anything.

Ok thanks I did see a change when I droped fuel pressure also I don't think the blower I used was that high in flow so it's probably not much of a concern at this point?

Atmospheric tests of combustors have their place if you experience problems with your combustor when running on the engine , but unless the test is conducted correctly it'll probably create more uncertainties than positive results .
LOL...............I've never conducted an atmospheric test on any of my flametubes/combustors , generally in too much of a hurry to hear the engine fire up .
Cheers John
