LT racing jet kit report...

[jimbolaya]

took it out after dropping the needle 1 position. temp around 80. with the a/s 3 turns out it was very close, but I'd still liketo drop the p/j to a 42 and run the a/s about 1 1/2 out which give me latiude for adj either way. I must say over all this jetting set up is very good. thanks Les Tinius!
jetting when I'm finished should be as follows:

mj=178
pj=42
jneedle=2nd position from top
a/s= ~1 1/2
#7 slide

This carb is fine up to 3 turns out on the air screw. Les told me that this carb is designed to have the airscrew in that range. I believe he was told this by sudco (keihin importer for u.s.).

With the 42 pilot and airscrew at 2 1/2 turns temps at 84 deg. the carburetion is more clean, but just after cracking the throttle open it doesn't sputter it's more like a raspy hesitation (It may be just part of the characteristics of the engine). I put boyesen dual petal power reeds on my 200 and that same situation cleared up. Maybe since I have the v force3 reeds it is causing the same lack of super smooth acceleration at barely open throttle position (I don't know)
I do know that everywhere else is awesome. smooth powerful acceleration!!

The reeds shouldn't do that, mine runs smooth and clean off idle. Try the #8 slide, borrow one if you can. Start back up to 45-48 on the pilot and middle needle position. The 250s seem much eaiser to dial in with a #7 than a #6. The 300 being a bigger pump may be eaiser with the #8. If the slide is rich the rest is a PIA.

Much thanks I'll give that a try!

I went ahead and ordered a #8 slide because it can't hurt to have it around anyway. Report to follow after it is installed.

Look forward to hearing how you get on with the number 8 slide, I've been having very similar issues with the LT kit. It's damn near perfect but I'd like to know if the 8 slide cures those little niggles.

My 08 EC 300 came with a N1EF needle, 178 main and 40 pilot.

At 2k altitude at about 70F it runs very clean on bottom and a little lean getting to WFO. The needle was at the #1 position, I raised it to #3 to see if it cures the lean spot.

Can i just add my 2 cents worth on LTR jet kits on my 2006 EC300? I had a noticeable splutter on 1/3 throttle in 1st and 2nd, but smooth as in all positions in all the rest of the gears. The LTR kit cleaned that up and mine carburettes perfectly now.

Thanks LTR!

Glenn I would love to try a #8 slide in my 300. I have a couple of #7 slides and would like to recut one to make it a #8. If anyone could take good measurements of a #8 slide and post them here on the forum I would sure appreciate it.
