What are you doing with the gas carbs? Target practice?

Jesse Open

I just converted a Fuji gaspoline engine on a RCM Super Sportster to methanol. Just like the old days on my go kart engines. Seems to run much better now but need to see how they hold up. Bottom line is, the Saito carbs may also have a second chance!





Here is a variation on the velocity stack.It really works well at cleaning up the engine room as well as a large part of the plane exterior.

The tube in this case is swedged to allow for passing thru the plywood mount. A tube soldered to the side passes vent oil to the carb intake rather than the intake passage from carb to valve area. No negative effect on running.

Never thought I would see an PCV system on a Saito, but there you go!

how about a glow Saito 120 converted to gas/w E Ignition, converted back to methanol/w E Ignition LOL. I have the stock 120 crab, and I just remembered the other day I have 2 or 3 gallons of straight methanol with 6% Castor, sO all I need is synthetic to add.

LOL Jim,
Whatever you feel like. Saitos are a ball to own .
FG-20 with CH ignition on methanol fuel .
Gaspoline is fine too

looks like Piglet fits the 4-Star 120 pretty good. so I don't have to cut holes in the canopy for his ears. I really wanted to put him in my 4-Star 60 with the open cockpit. but he is painted so I have to keep fuel off him. so he's going to fly the 120. and I'm sure he is a good enough pilot to handle the larger plane.

as for the silver backing behind Piglet, I got it from a insolated bag for shipping cold food. basically it's bubble wrap. well it's not glued down yet and I have more it, so I just noticed that some of it has a duller shine. so with less shine it looks closer to aluminum, so I will recut another piece. my plain is to cut it a bit smaller so you can see the yellow covering wrapped around the edges of the back.
but I need to make a boarder for the insolation. I thought about using a small diameter hose, slice the hose on one side and glue it the edges of the insolation. any one have a better idea on what to use for making a boarder around the silver backing??

Give Piglet a coat of a flat or satin Polyurethane that will protect his pint from any fuel.

Piglets make great pilots there Jimmie. Can't beat them Vemont piggys.

did you ever read that book written in Vermont, about Vermont, and about Vermont pigs and a Vermont family "the Day no Pigs Would Die".

I have used it 30 years ago, but it was not clear when it dried, if the flat Poly is clear when it's dry I will have to find some one that has some, cause I rather not buy a half gallon just for Piglet and never use a drop of it again. well, unless it comes in those tiny cans like stain does.

My 125 has a barrel spring but closes to about 1/64", I didn't try it without the spring, it won't run a 1/64" inch so I ain't a-worryin about it.

Jim and Quick, you should get your little packages in a couple of days.

Jesse Open

Thanks Dave, Nothing to worry about there.

If you do use Poly, make sure it is not water based, fuel eats right through it.

Hyjinx

And the oil modified ("poly") urethanes don't remain clear, (or start out) clear.
Automotive urethanes and clears will resist well , but color overcoated with five minute epoxy will remain clear and holds up to any of the fuels we commonly use if spills are removed for me anyhow. I put it over most enamel basses and you have a very clear fuel proof overcoat over a good resistive finish to start with.
Have also mixed the enamel into the epoxy successfully for a single coat application for a clearless flatter appearance. ( Like black or silver for fuelproof firewalls)
Krylon fusion will mix and dry normally. Small quantities, local availability lots of colors.
Far less expensive than the auto urethanes and necessary reducers and quantity purchases, just to go bad in the can in a month....
Bread crumbs. Lol

Great tips.

OK, thanks for replying about the Poly!! I will read it all again later.

but I have a real problem now, I can't get the prop of the 120. it wont move!. it's wood Xoar, what should I do ??

you see I have to remove the engine because the carb is locked up, and I have to remove the prop because it was not balanced.

thanks!

Take the spinner off and double nut the end of the crank. That will allow you to hold the crank still with a wrench so you can work the prop loose. Good luck Jim.

PS, a heat gun works pretty good for releasing "castor stuck" carbs.

Jesse Open

Even more controllable, just use the tip of your Weller soldering gun into the carb inlet. The localized heat with a bit oil, works miracles

You can often do it right on the plane.

Thank you Sportster!

That’s interesting. The barrel gap I saw was much larger. I stopped by my LHS to look at a used fa-125 (early version) they have on consignment. It did not have a spring. Then I received this reply from Horizon today. I’m not going to worry about it anymore.

Lonnie & Gary.

Lonnie, LOL just slap me, I should have thought about that ! well that worked out pretty good for me, but man I never saw a prop so tight on the shank Lannie !

Gary, another funny here. I had a 35w Radio Shack solder iron. what junk. it took a long time to heat up, then it would cool down, so I had to wait for it to heat up again over and over. the thing was hardly used. well. the last time I used it I checked Towers, and I saw they have a 45w iron. I got right up and went in and cut the power wire off my iron and threw the wire in my scrap coper box. I still have to order that new iron.

Jim

Jesse Open

Bingo!

Thanks for the update.
