I am a new owner of a 1974 FJ40. PO has installed (? correctly) a Holley carburetor. Fuel "spews" while running. Local mechanic says I need to rebuild the Holley, or replace it with new carb. My question: What carburetor should I have installed?

I just ordered a Weber 38 from TPI for my '71 (2F). My stock carb is on its last legs and started overflowing with gas through the pump boot. I'm sure it's just a stuck valve, but I don't want to wait for a rebuild at the start of summer, and really just want something simpler that I don't have to tinker with all the time. I'll trade whatever benefits you get from the stock carb for the low maintenance and peace of mind of a new Weber.

I've had the choice of many different Aisan carbs over the years, the original '74 (with the mechanical secondary) is my favorite.

Troll Holes carbs are about the best you can get I think. No smog mumbo jumbo and they run amazingly well. If you can find a Aisan they are pretty easy to rebuild. If I can do it I think just about anyone can. Weber is not a bad choice either but I can say a weber is not maintenance free. I'm always tinkering with the weber I own.

I have never seen a truely bad carb; just some are better than others for certain applications.

If the fuel is overflowing the bowl from the vent tubes, the quick and EZ thing to do is take the top cover off and clean out the needle valve and make sure the float swings freely. If there is junk in the needle valve, you might want to replace the fuel filter and consider where it is coming from. It is a 30 minute job and probably won't cost anything if you don't tear the gasket when you take the top off.

Weeks ago I did some simple mods to my 2 barrel Holley 350 CFM carburetor. Before the mods it would always flood when off-roading. Now after removing the float bowl with center hung float and adjusting the float to base line with spring loaded needle and seat, installing a vent baffle in to the metering block, fixed a vac line from metering block to the distributor, and installing a 2.25" vent tube... the old F motor purrs over steep jagged rock crawls with no issues! AND on the street the motor pulls very smoothly with great power - from stop/take off and threw all the gears to highway speeds! Working on the Holley was so easy and cheap and performs so well that I would not hesitate to do it again!!!

V8. Tried the Holley for about 20 minutes. Bought Rochester from Sean Murphy injection. Works great right out of the box.
