No I did not!
I cut the carb 7.6mm approx, I just left 1.4 mm to place into the original gasket of the tt, I also used the original gasket of the os to create a seal in between them. the screws that I used are little to long so I place some carbon fiber as spacer, but I will look for the adequate length.

My Posts This: Topic  Forum		Ren,

So you just cut off part of the body that would normally set into the motor/flange correct? Not bore-ing it out, just cutting it off?

Sorry for the dumb questions, just trying to be clear on what is needed. I like the idea of not having to touch the 53.

My Posts This: Topic  Forum		If I get done with a more pressing project tomorrow I'll start on the OS carb adapter. The OS 60L carb OD is 15mm which is a direct fit into the RL carb locator bore so you can actually use the OS carb as the locator to hold the carb centered over the intake. I plan to machine a 5mm thick adapter with a couple of slightly angled 3mm setscrews to hold the carb down putting pressure agains a little counterbore for the oring seat. I'll probably have to shorten up the OS carb a little but the net benefit is that if you wanted to you could hit the carb on a belt sander and with this adapter put the carb almost in the stock location without a lot of extra work. I'm also going to use 3mm flat head socket screws to keep the height of the adapter plate at a level so as not to foul the OS carb. Once the plate is done you'll be able to remove the carb by loosening the set screws and pulling the carb off. This should be interesting.

My Posts This: Topic  Forum		Mod results!!!

I had to modify the fan cover since the carbon fiber plate was touching it!
The engine has a lot more power than before. It is very smooth, but it has a high pitch sound. It might be the pipe, but I'm not sure because the pipe is new. The engine creates more smoke than before. The carb is always cold, and the case stays around 185 deg.
I try to over load it, but never happened.
The carb didn't move at all ( I was a lil concern about it).
If I had a way tomake the mod in a different way I will try since the plate require a lot of space around the fan cover.
I definitely recommend to try this!!!

My Posts This: Topic  Forum		Update , I have another 1/2 gallon of Magnum 30% through it and did some more Blade tuning and this TT53 has not missed a beat . Carb barrel moves so easy its like butter is in it and using only single pull rod . Plus the carb makes it breath like a angry beast and pulls like a freight train -15 +15 is just a breeze now.

My Posts This: Topic  Forum		Question for the guys doing this carb swap:

Are you guys primarily using the OS 60LH or has anyone tried the 40-E ?

Thanks,

Rayo

Is this a direct fit? No mod needed?

TM has not updated on his mod yet.The way it looks the carb would have to be machined some , leaving the motor alone. The 60L carb is what Im using also .

My Posts This: Topic  Forum		I don't think there would be no way to not mod the motor or carb in some way due to the fact it would be too tall for the fan shroud.
