Re: pulsejet go kart

Sorry I can't help with starting problems! But I do know that you can buy pipework, to join multiple bottles together, for caravans! Another option would be to use brake line tee piece from a car. The using s flaring tool you can flare and screw your brake lines together from each bottle. Join the c...

Re: new member introduction, also can i get opinion on ignition

Oh and I came up with a decent plan for throttle, I need to spend time researching because Iam not sure what to buy. But I think that if i only open the bottle tap enough to supply enough fuel for full throttle. Instead of 100% open. I should gain marginally finer control at the ball valve. I want a...

Re: new member introduction, also can i get opinion on ignition

Yes thats the one. Might try just slicing 20mm of the CC length, and crimping the injector a little more. Propane is a thick gas and it takes a "shredding" effect to have it mix with air. The large CCs dont need as much because they cycle slower and there is more time/volume for mixing. The smaller...

Re: new member introduction, also can i get opinion on ignition

Re: new member introduction, also can i get opinion on ignition

Looking good, have some earplugs handy. Ball valves can be a little touchy, can't wait for the video. Thanks Joe, i do have lots of ear plugs haha. by touchy do you mean, not very precise! all or nothing! Looks like its running rich for some reason. Intake to tail diameter ratio is at 0.791, probab...
