Tweaking the Linkert

Is there an on-line tutorial on adjusting the Linkert? I don't think mine needs rebuilding, just adjusting to get it to run smoother.

I don't know of any that don't simply repeat the factory service manual. The one in Palmer is very good.
Typical problems that appear to be adjustment (but aren't):
1. air leak*
2. wrong spark advance (typically fixed advance, or too retarded)
3. big cam
4. loose throttle shaft bushings
5. scar in carb body where throttle disc has closed against the wall
6. debris in idle, transition holes
7. needle taper or needle seat surface is bad
8. wrong float level
9. open exhaust
10. loose venturi

* carb body to manifold, manifold to cylinder, guide to cylinder, head bolt hole, valve seat

Panic's list is thorough, although I would suggest to add "loose venturi" for an even top ten,...
and move "air leak" to Number One.

Done, and thank you!

Cotton, Panic.....

Question for you guys.........

Today, I changed my brass float for Tom's DuraFloat.........(tom you got snail mail coming).

Question is...since I had the WLA running on the brass float and I spent quite a bit of time today making sure the DuraFloat is set to manual's spec's........

What needle adjustments, if any would I be needing to make on the M-88?

George, the best way I have found is to get somewhere where you can run at a STEADY 2500-3000 RPM, or so, (even if you have to use 2nd gear) and turn the high in and out till you find the Sweet Spot, then stop and do the same for the low. That's about as good as you're gonna get it!

George!

ALL tuning eventually comes down to trial-and-error, but...

If your motor has many overbores or any other modifications, even a civvy aircleaner or opened exhaust, then installing an adjustable HS needle into the M88 is a no-brainer (if you haven't already...).
Larry Elias's Military-look replacements are great, and conveniently available from 45PartsDepot.

Convention says to then eliminate the fixed jet, but I feel it just makes the HS needle more sensitive.

I agree - the flow through the Power passage will be at higher pressure, which makes adjustment more sensitive.
