WATERWICH compatible with Carburetor Chevrolet Chevy Type Rochester 2GC Two 2 Barrel 5.7L 350 6.6L 400 Small Block Engines Carb Kit

Fits the small bore Rochester 2 jet manifolds for 64-67 GM A Body 2 barrel manifolds with the use of two standard 2 barrel adapter plates bolted together. Mr. Gasket #1937. Requires a Choke heater tube. Dorman HELP! makes a few kits to refurb factory manifolds that had them. Flows very well. Only failure point I see is the cheap plastic filter behind the large fuel inlet.I needed this info and couldn't find it. So hopefully someone who has a Buick 300 4.9 310 Wildcat like me finds this and finds it useful.Or, if you're looking at the Holley 2 barrel clones. The 2100 El cheapo 2barrel on here works the same. Still requires a #1937 adapter ate but only one. This carb flows more. It flows more than a rebuilt Rochester 2 jet unless it's been modified for track use.

I'm amazed! I would have bet that at this price, the car wouldn't idle, or it would leak, or the idle screws would be useless but the carb works amazingly well. There were three gaskets with the carb, a thick one, (about 3/8"), one for the top, (air cleaner seal) and one that looked like it went to a thermostat housing, (which I didn't use). I bolted the carb on, cranked the starter for about 10 seconds, (no priming) and the engine started and idled perfectly. The air mixture screws were preset at 1 1/2 turns and all screws were tight. The only downside is that the thick base gasket only had two holes in it, (I had to drill the other two myself, (be sure to back up the gasket with a piece of wood because it's fibrous and it will leave a rough surface that will have to be trimmed a bit). Also, the base gasket may not cover all of the area on the intake that supplies vacuum, it left some exposed on my application which would have caused a leak. I used this carb on a 1971 Buick 350, (the linkage on the drivers side would have touched the intake manifold if the carb hadn't been raised up by the thicker gasket). Compared to the price of a real Rochester, this is a killer deal.

Overall great carb for the money. It seems to be setup right from factory. Idle was only thing adjusted. It had a vacuum nipple damaged but the packaging was fine. So it appears to have happened before shipment. I epoxied it back into place and good as new. Would have been 5 stars if not for that.

1967 C100 . While this carburetor, appears to look exactly like a Rochester 2GC. It isn't. I purchased this part as a favor for a family member. We have yet to see if there are vacuum leaks. I am betting on at least one at the throttle plate.

This carb went on fine and fit like it should, and got my old dump truck running but it ran like crap when you went to accelerate. I think the squirters are too small. I put it on a 350 chevy and I was able to get it to idle fine but the first time I started it fuel came squirting out of the top of the carb bowl vent. Ok so maybe there was some dirt in the tank of my old dump truck so I cleaned the needle and seat and had to readjust the float because it was set too high for one thing. Put it back on and solved the leak problem but the engine acts like it is starving for fuel when I give it gas and just wants to cough unless you rev it a couple of times and get a couple more pumps from the accelerator pump before it receives enough gas to rev up. And YES, I double checked the firing order, the timing is set correctly, the valve train appears to be operating as it should, like I said I think they just put either a very poor accelerator pump or tiny squirters in these cheaply built rochester take off's. If you buy one, be prepared to retune it and replace several parts to get it to run right or just save your money and get a REAL Rochester or a Holley. My 2 cents.

Hasta ahora de mi agrada.

buen acabado
