That is the only reason I have ever seen given.
In that case, not out of "need", more for a desired improvement when adapting to a totally different fuel. It sure helped my S-40 run better on gasoline back in 1981.
If you were happy back then with the way yours ran on gasoline, that's all that counts.
No "need" indeed!

Back then my sole gasoline engine was a MERCO 61 petrol engine that had a cam operated switch on the carb to change the timing from 6 btdc to 28. It had a very precise carb with tiny passages. I sent it to Terry Grant and he mounted a C&H Ignition Synchro-Spark unit. The original ignition was made by Premier Plastics and was very week.
The MERCO 61 petrol has the large prop driver.

What plane were you flying that big Merco 60on in 1981?
My old ST gassers used breaker points originally. They were home- made as there were no store bought CDI units on the market yet.

ST and OS carbs have always been trouble free on glow for me. Fox had the worst carbs on the planet judging from the few I had. Never tried to run gaspo with a glow carb.
Speaking of gaspo I'm hoping my FG21 doesn't require needle chasing at each outing. I go to the field to fly and with limited time to be there I need things to work right. Any plane exhibiting engine trouble goes back it the truck. I'm pretty good about keeping my planes running great and usually fly all that I bring to the field but I'll be darned if I'm going to remove a cowl to readjust a gaspo carb at the field. I've had tremendous success flying cowled 2 stroke gassers but I do have reservations about the the Saito gassers. Specifically, I steered clear of the early version fg17, the fg20 and fg30 as those have well documented issues.
When I receive my ignition for the fg21 I'll be thouroughly testing it under different weather conditions before it ever sees the nose of a cowled plane. If it's too finicky it's history.

This is the next FG-20 that I will be saving from its tragic gaspoline fate.
CH ignition is on the way. Will be trying the FA-100 carb on this one. Most likely wind up with another 125 carb. Fits and runs perfectly.
The FG carb cadavers donate a few parts on their way to the trash can graveyard.
Yes, on the Super Tigre and especially OS carbs.

I understand why you are converting the fg20's back to native fuel Gary, lots of trouble with that gaspo config. The fg21 is supposed to have fixed a few of those issues.
What numbers are you getting after converting back to metho with spark?

A fella could put a lot of planes in one of those!.......
.......and a workshop, small kitchen, bathroom and a bed. No need to ever go back home!
hmmmm......Oh wait, I have that wife thing.

No sir, would love to burn nitro at that level
When I was racing go karts in the 1960s it was hard for my paper route budget to compete with the guys who could tip the nitro can. I was limited to 40 cents per gallon methanol. That nitro was $1.75 per gallon!

The only source a bicycle based kid in my area had was the motorcycle shop, 5 miles from home. The stuff came in one gallon cans. A buck and 6 bits was the going rate. With all the other costs, that was too much for a regular diet. A few years later when Don Garlits lived a few blocks away, it was real easy to get. By then I was no longer karting.
I keep around 10 gallons in the shed nowadays

Only took me five minutes to do the xmas shopping this year.
Just a quick reminder for xmas guys if you store (in certain quantities) lipo batteries, nitro, methanol or fibreglass catalyst etc in your house or shed/home workshop. Check your policy. In australia it's quite easy for an insurance company to contest a house/workshop fire claim if you store things like fibreglass catalyst. The plastic containers with the paper labels split the caps over time so you don't want to knock one over and not notice. Years ago i had some in a glass bottle which i dropped on a concrete floor in the business workshop, the puddle of catalyst began foaming on the concrete so i washed it down with water. Most of the broken glass was held together by a large paper label so instead of throwing that in the inside bin i placed it just outside the workshop door and drove home that night. Arrived back there next morning and see a large sooty stain up a wall, yup it caught fire. Fire investigation technique is very advanced these days, would be a shame to be told to jump up your bum if you've violated the terms of your insurance contract.
ps erieqc bet i could land the fa82 powered decathlon in that trailer

Actually, nitromethane and methanol are less volatile , and harder to ignite than gaspoline .
I also dilute the nitro as soon as it arrives .
I don't have any gaspoline stored on our property at all, aside from the fuel tanks in the vehicles. The model fuel is stored in a shed., as far as possible from our dwelling and neighbors. Always in metal cans, never plastic.

I remember a friend of mine back in the late 70s talking about German machinist named Otto who lived on the coast use to do custom breaker point conversions to spark ignition. I considered have my OS open rocker .60 converted at the time. I ended up never running the engine and sold it to a collector to finance my return to RC in 2004.

Need a needle assy or a rebuild kit for a Fa90t with a bent needle housing. HH can't help. Who has a source?

How about this guy: https://www.horizonhobby.com/spray-b...-aa-sai100t122
For a T or 90 TS?, thanks, the engine code for 90-T is Q

Horizon hobby does not have either.
The motor in question is a 90 twin. FA90T.
No other I'd showing on it.

The left side needle barrel is bent. The needle gets super tight near the normal adjustment area section ( at the bend).
Pain to tune.
The assembly seems specific to this carb. My other parts motors and spare parts won't fit.
None of my shelf ready motors are right to rob one from.
