There is no real universal setting on the Low speed needle. Alpha different low speed needles on their engine models and the Older Alpha carbs had slighlty different needles as well.
However all he high speed needles are pretty close to flush on the high speed needle.
So set you idle gap opening ( remove carb restrictor,look down carb and close the idle gap until ther is just barely no gap, then go in exactly 1 full turn in and the idle gap will be very close. put restrictor back in.)
Set low speed needle to flush with housing. this will be rich but you can lean the low speed needle a couple hours at a time until you get a solid idle.
This will get you in the ball park then you can start over with the high speed needle and get it fine tuned, then go back for the final low speed setting.

Hi guys, just unwrapped my new Alpha 21 club racer ready to breakin tomorrow but after reading posts on here i think there is something wrong with the factory setting on the LSN, everyone on here is talking about X amount of turns from flush but my LSN is all the way in!
Is this correct or not?
Could anyone advise me on the factory settings for the 21 Club Racer?
All advise appreciated!!

Make sure you let guys know if they are the old stock parts on the Piston/sleeve sets. Some of the old stock parts had machining issues, they have all since been corrected but would be good for people to know.

Which alpha engine should I get for my buggy. My priorities are easy tuning and fuel milage.

Any of the .21's..... They all tune easy and get great fuel mileage..... Some have more bottom end (S852, A852) and some are buttery smooth (A872). The F850 is a combination of both.
I cant comment on the Z852 only because I havent personally run it yet.
My personal preference is either the F850 or the A872.

OK. I change the question a little. Which motor will have the most millage with a alpha 2090 pipe that I allready have?

if you are looking for run time the Lutz or A852 is what you would like, both make 10 min pits for me no problem when running with 0801 pipe. however, these engines have alot of bottom especially the A852 so you will need a smooth trigger finger. 2090 helps with the low end.
also the F850 is in between the Z852 and A852 power wise, good all around engine. 2090 is a nice pipe to smooth it out, i like the 0801.
the A872 is very smooth on bottom and never tops out but i cant get the run time out of it like the other, its probably my driving style because i see people getting 10 with it. 0801 or 2081 is best IMO
hope this helps.

To me it seems the 2090 is a perfect match to the A852 and Lutz edition. I havent run the Lutz edition. Both of those have a very strong bottom end. With my A852/0801 I could manage 10 minutes in a buggy. The 2090 will help with mileage and will also help to tame the low end down some...
