If I should decide to be stubborn and try to use this carb.....It has
primary jets/75
primary rods61s
secondary rodsEK
no extra tubes on the airhorn
single main air bleed
.038idle tube
channel restrictor .070
main air bleed.086
bypass air.055
upper idle bleed .068
lower .076
 What you think........a rebuild kit with which primary rods & jets would be suitable?
A large 75 primary jet with an even larger 61s rod sounds too lean for a stock 442?

Thanks

Cliff Ruggles:
That jetting sounds like it may be a motor home or BBC carburetor?

It will be fine for what you are doing, but I've never seen the idle downchannel restrictions at .070" in those, that I can remember.

I'd go up one jet size, and smaller secondary metering rods, one of our kits, and make sure the pull-off and e-choke are working correctly.....Cliff
