Bill,


Thanks Bill and Jim for the backwards running info.

I've never found a Saito to start easily cold unless it was sloppy wet with prime, and the throttle at least 1/4 open. Doing it this way I also have never thrown a prop or had a nasty back fire. Before I learned these two tricks it was always a battle to get the first start of the day.

After the first start the sloppy prime isn't needed, but still the engine wants that 1/4 throttle until it warms a little.

Bill.

Barry, a sure cure is to try and start it backwards and it will starts forwards, best starting method I've tried. The bigger the engine the better it works.

3-32 fuel line for the 180 good?

gjeffers

also im ordering a goldberg pitts p12 monster, at 12 lbs a 17x6 would be a good prop to start with?

thanks guys!! thats for a 180

Gary,
Wow!
I'm jealous!
I always wanted a Pitts.
Make sure to keep us informed on how it does with the 1.80!

I guess I am a new victim. I have a new 125 on a showtime. I have been a long time magnum user, thought I'd try something new. One reason is the info from Mr. Robinson's insight.

Thanks, I think

Gary,
Is that your oil well in the background?

The FS S-12 has the Vendenyev M-14 rngine, and a three blade prop.

If it weren't for the weight I'd say the FA-325R5 would be a much more suitable engine. But since the weightg is a factor, have you thought about the FA-170R3?

Staying with the FA-180 I'd try a 16x8 three blade, might need to go to a 16x10 or for better aerobatic performance a 17x8.

Welcome to the madhouse.

I have long been a Magnum fan also, and still am in two stroke engines when one of my trusty K&B engines wont do the job.

You will not regret switching to the Saitos.

You are in aas number 254. Again, welcome, and thanks for the kind words.

Bill.

More on stacks..... like we need it!

Anyhow, I just put a stack on my .56, fitted perfectly, holes and all. I used an 'O' ring to seal the gap, 8mm I.D. x 1.5mm thick, made of Viton. Makes a good seal and doesn't seem like it can be sucked out, feels quite snug in there. 2 tanks through it today, no issues. And not a drop of fuel escapes, works great.

Thanks to Bill and this thread, I would have never known about it otherwise.

Cheers from the Barfly.

Sometimes, granted it's rare, but sometimes we do get things right.

Thanks for the endorsement.

Where did you buy Viton? Is it a common hardware tubing?

8mm I.D. x 1.25mm thick, made of Viton.

Thanks!

Ok Bill I'm a memeber in good standing on RCU again and I onw a dozen or more Saito engines. When do I get to be a member?

bldrums

I just reassembled my .91 after a glow plug re-thread repair. I runs just fine but I wonder about engine temperature. I'm paying close attention now with the intake stack and repairs, valves set on the close side and a good crock pot cleaning. ( I know they are always hot after running a tank ) but , the oil was very dirty so for kicks I measured the temp at the head cooling fins . This was probably 10 minutes after shutting the engine off. The reading was 130F. What are the expected temp ranges for the four strokes? And do you generally see very dirty/black residual oil after this type of maintaince? I plan to re-check the valve clearance once its dead cold.


Thanks, Bill

If the black oil is out the exhaust I have no idea, but if it's from the crank case vent you could have put the con rod in backwards. Pull the back plate, see if there is any amount of wear marking on it.

This is funny, have you noticed that when you click on "glow engines" a few people post general questions, keep moving down to CLUB SAITO// 2500+ people just turn here and come on in!!!

Business is good at Club Saito One Stop. Its the members of course that make it great with W.R. making sure we don't exchange any questionable advise. [:-] How does he do it all?

Talk to me about engine temps. After a full tank run wot, what range would I normally see with a direct measurement just after shutdown. No cowl ( .91s) running 10% with caster oil.

BillD:

If you measure at the base of the glow plug (you did say contact) up to 250F is safe, but usually around 220-230F is normal running temperature. When the engine is shut down the temperature will rise a bit, from stored heat coming up from inside - lacking the air flow it wont dissipate as quickly as it will with the engine running.

Using an infrared noncontact thermometer I've seen up around 275F, the exhaust side runs hotter than the rest of the engine. The muffler can get up around 500F without indicating any problem.

Getting up to 300F or more, except right around the exhaust port, is definitely cause for concern.

This a great thread and I love these Saito's. I have a Saito FA45 that I put a FA50 cam in. Runs great. I also have a FA56, FA91 and a FA120. I need a few parts for the 91 and 120 and thought I would see if anyone on here might have them in the box of everything we all have. I lost the muffler on my 91 and my 120 went in and cracked the case right behind the front bearing. If anyone has a muffler or case that they would want to part with please contact me.

Thanks

Bill,

You certainly do a great job with sharing your knowledge. I have been lurking for the last 100 pages and now it's time to fess up to being a Saito owner. I have a 50, two 91s, a 100 and another 100 on the way. Please add me to your Saito Club.

Last time I checked the cylindric muffler was still aailable for the mid block engines, it and the curved head pipe together are less expensive than the later cast muffler alone.

On the FA-120 a new crank case and a bearings set are much cheaper than a new engine, and not hard to install.
