"running rich" could be anything from a heavy float, to a worn carb.
do you smell fuel? could be a seeping leak.
do you see fuel? coming out the vent tube? heavy float.
a vacuum gauge will tell you a lot about what is going on.

Will a carb from a 351m fit a 351w?


I don't see why it wouldn't. If there both 2 barrel or 4barrel it shouldn't matter. How ever you do have to pay attention to how much fuel the carb delivers. Like 750 holly or a 650 holly. Some 351modifieds used a Ford carb and I can't remember how much fuel they deliver. You get to much fuel to your engine and it will put out black suet from the tail pipe. This can cause damage to the piston rings over time. The tail pipe should look white or tan in side if the fuel mixture is right.
I hope this helps, I have been a ford owner and mechanic for years.

How to adjust my toyota 4k carb installed in 2e engine?


probably the most hard question ever posted in faxya.

how to tune any carb.

google it and read for 1 full day..

endless story.

how id do it is different than you, or old school.

I have a wide band oxygen sensor i can put on any car.

and tune anything. (gas)

the jets need tuning.

here it the steps before

1: 100% clean every inch, (called "boiling out the carb") or kemdipped.

2: kitted, put in a carb kit, gaskets, and all the bits.

3: make sure choke works. turns off , on a hot engine, if not MPG WILL SUCK.

4: fuel pressure as spec. not 15psi,., better is 3.

5: float level to spec. (new carb)

6: tune it. (thats the long story.)



done many. and have cars in my barn that use carbs and motorcycles.

Something internal in the carburetor is wrong, maybe the accelerator pump seal or gasket is bad. Think you will have to put a rebuild kit in the carb. There's no outside adjustment for it being way too rich.

Got a 85 ford f150 has a 302 holly carb. was running fine ran low on gas and now cuts out wont back out of drive way idles fine but hit the gas and it stalls


strip and clean out the carb,or quick fix ,rev engine with air filter off and then hold hand over intake this may or may not not cure it .because when hand is held over carb and stops air the suction will draw any muck through the jets

1985 300 runs to rich


Is it a Holly carburator? If it is and the choke operating correctly, then you have a warped metering plate in the carb allowing too much gas to go into the engine. Rebuild the carb abd check the plates for warpage before reinstalling them. There is also a power valve in the carburator that some times goes bad. Good Luck,
