New (to me) 7.90 Rhino question

Postby csracing » Wed Aug 08, 2018 10:58 am

I've got a 3.5x3 Rhino engine due tomorrow. Has a 42mm carb on it. Couple questions for you guys as this is the first time I'll be running this carb.

1) Jets the same as a 33?
2) Will a throttle cable from a 33 work in the 42 or do I need a new cable?
3) We have a 2008 Bos car with no weight and a 85# driver. I expect I'll need to add weight. I have a behind the seat weight tank. Not sure how much it will hold, but any ideas on roughly where I should start?
4) Any tips and tricks to tuning the carb that you'd like to share would be appreciated.

Thanks

Cable will fit providing it's long enough to reach the new carb.

As for jets, I would skip the mikuni jets and get the adapter for the Holley jets and use there Max jets.

Kinda hard to say where to start weight wise without knowing what this motor is replacing.

Current engine runs 8.90ish with no weight. It's Animal-based (LO206) so probably not a lot of help to you there.
