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.
