New to Gasification - Where to start?

Here is a post of the last run. It ran about 20 min. I was pretty pleased with it for first time run.

I was surprised at the amount of moisture in the filter.

Im starting to make some new charcoal and hope to fire it up again this week end.

Hey Joe , congrats on your run , if it is a flat head then Your Doing ok as they have lower compression than the more modern Chinese clones of around the same size , i have in the past run engines as small as 50cc but you do need to size the nozzle accordingly so that it keeps up the temp and makes strong gas .

With that wet /damp filter your showing in the photo i would recommend you maybe run some petrol through for 5 mins after shutting of the gasifier that should help dry out the carb and get rid of the fine dust that builds up around the butterfly .

Thanks Dave. I did mist the cylinder with WD40 after the run because i figured it will be awhile till i fire it up again. The gas idea is good. Thanks.

My filter is according to Gary’s design. It is 4" of open cell foam then a thick piece of wool that is held away from the exit hole with a metal cage type thing. All of this in a 5 gal bucket. Ill try to get some pics posted.

Hello JoeB
I suggest trying next on your filter reversing the foam and sheep’s? wood felting.
If it is actual sheep wool it will have a higher temperature resistance and be soapy water washable-reusable.
The open cell foam is common (cushions and mattress’s) so just trash it when loaded and replace. It will flows drain out the bottom. So make your outlet pipe up off the bottom. Have a captured condensate drain on the very bottom.

I like it! Ill work to implement that. Im gonna look for a new bucket with a screw top also to make access easier.
Was wanting to make a new batch of coal but its raining and 50 mph wind gusts here. I think ill wait for a better day :face_with_raised_eyebrow:
Kind regards, Joe

Hi Joe , it is mainly the carb butterfly that needs cleaning not really the cylinder walls the moisture in the cooler area of the carb is what causes the fine soot to help seize the steel or brass butterfly pin to the aluminum/die cast body .

Yea, makes sense. I’ll clean it next time at the end of run. For now I’ll spray carb inards with carb cleaner or wd40. Appreciate the tip. All these small details make a big differance.

Kudos on stabilizing the mixer valve to the frame, your carburetor mounting studs will thank you! Thanks for sharing.

HI Joe, yep good steady running there , is it underload ? if so what are you drawing power wise ?
With all good intensions i would recommend placing a air filter onto your mixer valve asap , last thing you need is to kick up some of that dirt and dust around the machine other wise it will interfere with your fun.
