BTW, Castor oil is an excellent assembly lube, provided you run the engine within a few months. Actually darn near the best in that case.

Lonnie,
I trashed the Saito ignition and used an RCexl in its place. Also used the CH trigger mount which is a huge improvement and works with the factory mounting holes. Sure beats tie wraps that some folks insist on.
The Saito has carb was stripped of a few useful parts like the throttle arm and fuel inlet nipple, whacked with a hammer and dumped in the trash can.
The stinkoline carb uses four flanged plastic bushings and smaller diameter screws for mounting. Those bushings and screws were transferred to the methanol carb.
You could easily tap out the holes to use standard screws and, most likely a shim the same thickness as the bushing flanges to keep the right position.
The intake pipe (everybody calls it a manifold, but it isn't
) was used. I did not compare part numbers but the pipes may be the same, they are at least very similar.
Heat insulation bushings

Thanks. Which rcexl module did you use? The older one that required a static timing of 40° btdc or one of the newer ones that get timed at 28-30° btdc? Just curious if that CH bracket has enough adjustment to compensate for the 40° btdc magnet position on Saitos when using using ignitions set up for 28-30°.

Found this image on an FG20/21 thread. The pin hole in the carb body next to the high speed needle indicates that this carb is the updated version for the FG20. The FG21 uses the same carb. Very few people had any luck getting their FG20's to run right with the older carb but most have no problems with this updated version. Sorry if this has already been covered on this monster thread.

Saito FG21 transition problem
For those running saitos gassers, do you have ongoing problems when quickly transitioning from idle to wot? Mine gasps and quits. No backfire, just gasps like there's not enough fuel for transition. Richening the lsn just leads to an idle which continuously drops rpm until the engine quits. Leaning the lsn leads to idle increasing rpm until the engine quits. Where I have the lsn set right now it will idle at 1950 rpm +/- 25 rpm all day and as long as I don't transition to wot too fast it transitions fine. Runs fairly smooth at all throttle settings too.
Anyway, is this normal behavior until the engine breaks in further? Will the problem eventually go away? I've run almost 1/2 gl of fuel through it so far and have tried static timing settings ranging from approx 27°-34° btdc using the Rcexl V02 cdi. No joy so far.
prop is a xoar 15x8
fuel is 89 octane 20% stihl ultra hp,
temp 50°f
battery is a LiFe 6.6v
peak rpm 8200
compression is excellent
no valve leaks
valve lash set to .002"

I used to be Charley on RCU but now I can't log in under that name and the "forgot password" function doesn't send me an Email. I had to reregister as Charley38 using my Gmail account because RCU won't let me use my twc account; tells me it's already taken. Sent admin a query yesterday but no reply. Don't know what to do in order to get my original account working again....

Nope, all mine run fine, FG-11 and FG-30. All run on factory settings. I use 93 octane no ethanol fuel with Amsoil oil.

I hope Pete is OK, record breaking temps down under. 107°f nationwide average temp and in some places temps of 122°f were recorded. That's smokin' hot, literally; they have a over a hundred wild fires going on right now.
Oh what am I worried about, he's probably sprawled out in a swimming pool full of ice and beer right now.

Pete is just fine, I received an E-Mail from him a couple of days ago, somehow the new software can't send us a new password if we have forgotten our old one. It'll be fixed in a day or two.
Happy Holidays to all the Saito Buds.

I wish there was a website you could plug an address into and it would show you what the exact spot on the other side of the world would look like. With my luck its either desert or open ocean.
