Saito 65 fuel inlet early carb, 5 x .5 thread.
Saito 65 fuel inlet assembly, complete, early carb.
When screwing this onto the carb body, be aware that it can be screwed in too far and run into the carb barrel blocking the fuel flow and possibly pushing the barrel through the snap ring on the lever side.

I just realized why I like this thread so much. We all have the old fashion idea of if something breaks we fix it. We don't use it, abuse it, throw it away like the younger generation of today.

Probably the same o ring groove. May have to resistance "braze" the silver soldered fuel connection. Hard to do with even the jewelers torch but should work well on the big soldering transformer with a pair of carbon rods.
Yep, Thats why in AMA racing, Harley was allowed to run their 750cc engines against 500cc Britbikes in the early 1950s

This right here ^^^^^^^ is why I like this thread. I learn something new most every day. Had to google "resistance soldering" to see what it was all about. Pretty nice science for delicate work. No doubt Gary fab'd his own RSU....lol

Once the Sportsters went o OHV the game changed.
Soon they were all running 750 "V" twins with chain drive on 1 mile dirt flat tracks..

About the same if it just crawls off the runway and cruises through the wait awhile bushes/trees,it's always the first section that you find on a recovery mission just kidding.Bruce you should have got two small wire tools,one has a flat blade screwdriver tip for the hsn and the other is threaded for the choke.Tuning one is very different to our fa engines.

The needle assemble had no O-ring on the early carb, it does now but there is no groove for it, the O-ring just ended up inside the needle clip. I probably wasted it. Those resistance solder machines are expensive. I put fake Swak on the threads.

Dave,
Thanks for the info, Ill see it if and when he sends it.
The resistance solder machine I use is just a big transformer with multiple taps. I make up carbons as needed. Paid all of $35 for it at a local flea market. Just about any low volt/ high amperage transformer will do if used with a 15 amp variac on the primary. Just have to know what it takes and where to look.
I get the carbon blocks as scrap leftovers from a local EDM guy that I used to build machinery as a "side job" for.
That is the point.
In that case, a superior engine design more than replaced the displacement. It has been going on ever since then. BTW, The 750 Harleys were still often beaten by 650cc BSA and Triumph riders as well

Question on props. When completed I will be using a 16x8x3 biela prop on the FG-30. Before that though what would be the equivalent 2 blade prop in size for the same amount of resistance. 17x6 or 18x6? It will be a while before I get the actual props, going to wait until after the first flight.

While on a trip to Denver a couple of days ago I stopped by a BMW motorcycle shop to check out some bikes. I made the mistake of demo riding the new 1250 GS. Wow! That boxer engine. Now I want one.

Jim i went for a ride on the duke last sunday with two mates,one on a ktm 1290 v-twin and the other on a stroker harley with a lot of ground clearance and sticky race rubber.It may sound funny,but as a group we like to go 'slow around corners' harley hunting (well,i spose you would call them victims) and it was a sunny afternoon up in the hills.Our first targets appear and a pizza van whizzes past in the opposite direction.I was already smiling but then i remembered your pizza post and started to giggle in my helmet,there's no way you can drive or ride fast like that,so you got cursed over a beer later cause the harley rider creamed me.

my brother's old friend is a jeweler, I can see myself now in his shop, " Hi Tim, remember me ? I'm Tom's brother, can you solder this for me, it's for the Carb on my plane, but don't use gold" LOL

This should work also tossing the spray bar.
Saito 120/150 spray bar
This may be a possibility from the Saito 150 parts list.

Not too worried, an easy fix whatever direction.
Here ya go, got it handled. He is sending the carb. His engine should be running by the weekend.
