Saito 150 - won't start after replacing spray bar and high speed needle.

Yes, rockers and manifolds are in place and working properly. It rather looks the engine gets no fuel. But priming shows fuel coming off the muffler. Turns well with the e-starter but no
fire. Replaced the plug, all F-type and burning. What is to do?

RVM

Did you check the charge in your ignitor (or is it -er?)?

My Feedback: (16)

If you replaced the spray bar, did you make sure that the slot was centered towards the engine?

Luxuswaffe

It is igniter. What charge? Like voltage charge on the plug?

Luxuswaffe

Yes, slot centered towards the intake of the engine. But I am going to take the motor again apart to make sure...

RVM

Make sure the igniter is fully charged with electric power, so that your glow plug is getting power, so that it can get hot enough to ignite the fuel/air mixture.

W8ye thanks but I already ordered it back in sept and they say it should be sometime in January or february any other sites where I can order the carb housing.

Not unless there would be a Hobby shop that had one.

IMHO they have not been available yet.

Horizon hold the reins on Saito parts and most dealers just order as needed from Horizon

If the spray bar is broken from the carb body, it uses the "91" spray bar.....

Some glow plug ignitors are 1.2 VDC

Some are a pulsed set up with a much higher voltage. They just turn the voltage off and on real fast so the plug gets to the right temperature.

Have had same issue with spray bar for the 150. Ordered one directly with Horizon and the wrong part arrived 2 weeks later. Sent it right back to Horizon and got the right spray bar after another week or so. Parallel, I ordered a second spraybar with my LHS and they cannot deliver until Jan/Feb 2007(!).

Let's move away from SAITO! I am spending too much money into the hobby to only wait for some silly brass parts.

Slots are centered towards engine throat, charge is powerful - still won't fire up.

RVM

Have you tried adjusting the needles to their original factory setting?

Hello gents, Like to join. Have Saito 100, 72, 72, 56, and an OS Klunker 70. can't win em all... used OS.

Saito 72 on Sig Sr Kadet. Perfect match. 12x6 APC Seems to give right power and slow speed operations, but worried about overrevving. Can you throw out some good prop ideas and max rpms for longevity. Purrs like a kitty at idle 2000. Want the instant go around power for the trainer.

Additionally, the other .72 is about to go on my old hang9 Advance 40 that is tricked out a bit. My OS.46 just doesn't give me the pull out from the dance. Looking for a prop for it. I just bought a 14x4w for the OS and will eventually try it on .72. thoughts?

want HARD pull, dont care about top speed on any of my planes. What increase over an FX.46 can I expect?

The 13x6 MA K pulls hard on both engines, but on the Advance, I might have some ground clearance problems. want APC props.

forgive rambling...

I have all plastic spinners ( Dubro ) on my Saito 82 and my Saito 150 and they are very happy on these engines . I like plastic as it absorbs any kind of impact rather than the engine absorbing it.

We normally use on the 72 a 13-6 for sport flying.

But your plane has ground clearance problems.

You can run a 12-7 or 8 on the engine and that will tame the rpm somewhat.

I had a friend that used a 12-8 on his 72 for a couple years.

I thought I could use the plastic spinner that came with my groovy. It has an aluminum back plate and looked fine to me. But, after a about a dozen flights it broke internally where the bolts screw into the back plate. I immediately replaced it with a Tru-Turn aluminum one. DO NOT TAKE A CHANCE WITH PLASTIC.

That appears to be a ZAMA carb with an insolator bolted to an adapter, I can't see if the carb is attached to the backplate, the stock glow carb isn't.

Jett, I have used Graupner spinners on my 1.50 and a couple of others with no issues, their backplate is something that is really tough.

Hobbsy,

Do they make a glow spinner ? I just looked at a bunch of Graupner spinners and they were all for electric. Where can I get one for my Saitos ???

Hobbsy

My Feedback: (102)

It appears that they only have three blade Graupner spinners now, bottom of page.

I have a Saito 72 for a plane I'm still building. I have no idea how it runs yet, but it looks really cool. I open the box sometimes and show it to people. One day I will fly it, and it will be good.

The 72 is a superb engine. However, there has been some design improvements on the plastic backplate to make it more rigid. Do you have the improved version?

Luxuswaffe

SAITO 150 won't fire up:

Just figured what I did wrong: When I replaced the spray bar, I installed it the opposite way around, so no fuel could pass along the high speed needle; in every adjustment it was closed and no fuel got through the carb. Now the engine is purring like a big cat again. The Saito-manual is very poor on it's explosion drawing.

Just a note on the majority of the rc model manufacurers, since most printed matters are sometimes not readable, they do provide an online version which is in PDF, this in turn help modelrs to use the functions of PDF by utilising the zooming function on the pdf reader.

Just go to saitoengines.com then you will be linked to horizon hobby and from there you can select the right engines then click on support and select the manual link.

Hope that helps.

I believe towerhobbies does the same and QQ somenzini has a coloured version of his manaul.

RVM, regarding that Dawn cleaner, please be careful how you use it.

I used it and it gets of the light to medium gunk. As a test, I first cleaned an old Saito muffler - that got it about 80% clean. Then, I squirted it down with the stuff and put it in a plastic ziplock bag for 24 hours (so that the Dawn wouldn't dry out).

24 hours later, there was not much more cleaning done, but the metal on the aluminum muffler felt 'eched' somewhat. You might want to try this stuff out on a muffler of your own first, to see how it works for you, before trying it on something like any engine internals.

Just a thought,

Bob
