I need some ideas!

My combo has run 9.27@146.3 in good air. Beginning of year at the first test and tune car went a 9.33 spinning. Car has a SV1 that has a stumble at part throttle. Talked to Patrick and he said they have new metering blocks. Sent carb. back and he changed them. Put carb. on and it was worse then before. Finally with his help I got the carb. to quit breaking up but the car wouldn't ET. While the car was down I changed to 4.10 gears from 3.89. Put the carb. back to the old setup and ran Fri. night and the car only went 9.79@138mph. Now air was bad bad. I have checked the converter it is flashing at 5950. Did compression test all is good. Ran valves all is good there. Car isn't popping missing or acting up it simply has quit pulling. Pulled the plugs and front plugs are great. As I go back the plugs start to richen but not bad. Plugs 4 and 8 are coal black and sooted. These were new plugs. If it isn't a carb. problem what could it be? I'm at a loss. The car has lost about 110hp (50ish) from bad air I'm sure but where do I begin to look?

Don't know the SV1 persay, but with what you've said, you have raw fuel, not atomized, like possibly up and out vent tubes on conventional carb, hitting manifold floor and pulling/running to rear cylinders. Check float level, check base gasket, check for raw fuel out carb power area (don't believe SV1 has boosters like conventional carb) to see where this not atomized fuel is coming from.

cell that carb and get a quickfuel and quit screwing with it.

^^this........or put a rons toilet on and run your best et ever!  

I would follow Kim/Randy's idea's before you do anything drastic. There's a logical explanation ,it just might take a little bit to find what has happened. Your spark might have weakened too,might try another box if at all possible. Good luck Melvin. 

You can't clean plugs..... they go bad, you need to put new ones in.

I'd also try a regular dominator if you have one, I have heard of some engines having distribution issues with the one hole wonders. Guys either love them or totaly hate them.

IMO most responders to your topic and myself agree the engine is experiencing an over rich condition. The weather is part of the equation. As I read your original post the over rich idea became more prevalent, as the engine could not get on top of itself. I know nothing about the fuel induction system your using, but as others have mentioned I would try another carburetor to see which direction to take your effort.

Lol If we hadn't just dropped 3300 on the frontend for the new car this is what we would have done. What upsets me more then anything is the attitude I got from Patrick. If the car has raw fuel getting to it how is it getting there if it isn't through the carb? I will change plugs again and double check float levels base gaskets etc. I will also put a different carb. on and see what happens. Thought maybe I was missing something. Thanks for the replies and I will let you know what I find.

double post sorry

attitude alone is why I cant stand that m'fer, and all the PS carbs Ive dealt with were not worth a f-ck either.

This "mind control" will diminish with age! There will be a day when you rather have a bacon and tomato sandwich instead!
