elevation is about 1000' stock carbs with v-force reeds.

Stock carbs for the 99 or stock carbs for the 440?


If its for the 99

Stock jetting is.

MAG--- 190
PTO----185

Pilot--- #38

Needle--- R1368G. clip in #2 setting.


That elevation id run

MAG 185, PTO 182, 40 Pilots, R1371G needles, with a boost bottle. All will be safe with a stock pipe and you will get rid of that bog on the low end.


Stock clutching would be.

10-60 weights and a blue/white primary spring.

Secondary:

Stock:

Siliver clutch spring, with a mod strait 36 helix.



Id run

10-62 weights with a almond blue primary spring.

silver blue secondary spring with a R-12, hot seat 36X helix or a 52-36 helix whatever you can find. Any will work well.

Based on your weight sled may or may not want to pull 10-62's might have to drop down to 10-60's.

That engine should fly in that light chassis. Great swap.
