I built the attached pair of steam power modules for my 1/32 scale ironclad ram Keokuk. The boilers, burners, and butane tanks were built by Mike Abbott of Maccsteam to my specs. They have been sitting for a year so I fired them up yesterday. One ran like a champ but after about 30 minutes, the other one appeared to starve out from lack of fuel. I disassembled the gas lines and checked them for blockage but couldn't find any. I attached the jet straight to the tank and all I could get was a pilot light, so I assume that the problem is the jet. It is a No. 5. Does anyone have a source for jets and/or know if Mike made any special mods to his burners to accept a stock jet? I would also be interested in knowing of any sources for model steam system repair and maintenance if it is not the jet.
Thanks in advance

I ask this question regard gas jets, scroll down about 6 postings.
There does not seem to be any place in the U.S. that sells them.
I ended up ordering from
Forest Classics - Gas Essentials and Jets.

Had them in about two weeks after placing order.

Thanks for the heads up. I have talking to Phil at Forest to isolate the problem. He is my go-to guy for jets and regulators.

Hi, For cleaning jets there are 2 simple methods. - but 1 can damage the jet.
Use a pricker. - Actually, a drill of the correct size - for a No 5 jet this is a 0.20mm drill. I use the drills that come in sets from China for about $0.30 ~$0.40 per drill - in packs of 10 drills - with a 3mm diameter shank. CAREFULLY rotate the drill between thumb and forefinger and apply a tiny pressure when pricking the jet and any detritus should be cleared. You should act like you are removing a splinter from the finger of your 3 year old boy.... CAREFULLY!
HOWEVER - this can damage the jet and make it bigger, or you can break the drill! - so you may quickly use up the 10 drills in a pack! A broken drill bit means the jet is a write-off. So the wash-out method is preferred if it works on your detritus.
RECOMMENDED: Take and aerosol can - IN THE OPEN AIR - AWAY from flames, etc. and DON'T SMOKE. Use a Carb cleaner aerosol from an Auto-shop, or if you can't get one I have used butane lighter refill cans. Remove Jet from the burner - carefully holding in pliers or something - against a fixed object. Apply the nozzle of the can to the jet to the out side of the jet and give it a squirt. (BEWARE! If you use your fingers to hold the jet you are likely to get FROSTBITE from the freezing action of the liquid gas washing through the jet! Frost burns are VERY PAINFUL - so I am told. - I don't risk it myself.). Aerosol can stems are breakable plastic, and stiff to operate, so support the jet properly when applying pressure on the can to give it a squirt. A broken plastic stem of a can is a waste of a can...
The advantage of back washing the jet - especially using the carb cleaner aerosol - is that you remove deposits that are blocking the jet WITHOUT risk of damaging the jet orifice size. This is CRITICAL for correct and safe burner action. - A bigger jet than originally designed - even by 0.001in. - can cause the burner to produce Carbon Monoxide - which is a deadly poisonous gas.
Sorry to be an Old Werrit about safety - I'm a survived motorcyclist. (The only activity where the Authorities don't actually publish the death rate or permanent disability rate! - more than the 15,000 per year deaths by bullets in the USA).
Beautiful model, I'd love to see the boat it will power...
Enjoy!
Ken

That is a beauty of a setup!

Very nice. Definitely want to see more pics of the full thing!!

As for the burners I'm based in Ireland, so probably not much use to you. Polly Models in the UK are pretty damn good!!

Cheers,

Del

The Train Department here in the US carries a lot of the European manufacturers (Regner, Roundhouse, etc), they
have jets listed. I would suggest contacting the owner there, Jason, and ask specifically about the part you need.
