Another carby question

[Anonymous]

Guys, I'm looking at replacing my troublesome YF with either a YFA or an RBS or a 5200.

Which one would yield easier tunablility? Up side / down side? CFM ratings?

Thanks everyone!

The RBS is a real simple carb to work on, and they can be had rebuilt at parts houses for around $85 w/ exchange.

I really like the 5200 though. You can get them even cheaper than an RBS (www.stoveboltengineco.com) Lot's of adjustments can be made. They use Weber parts. Idle jets, main fuel jets, main air jets, emulsion tubes. Jets aren't cheap, but they are certainly available. The problem is, you have to know what you are doing or have some help. The downside is linkage, hood clearance, and air filter. You'll need to come up with something in those departments or copy someone elses setup.

I'm still waiting to see someone put a 5200 directly to the log. It would be so simple....

Well, if I go with the 5200 I planned on having my log milled to accept it directly. Do you know if the 2100/2150 and 5200 have the same bolt mounting pattern?

No, the 2100/2150 uses a Holley pattern. The 5200 uses a Weber pattern.
