Weber Carb Questions..........

[strat1960s]

I have the Weber 38 DGAS carb on a 1968 200/ inline 6. I had some machine work done to the motor, port and polish, spin balanced, installed an Australian head with roller rockers, installed an Isky cam-shaft and a port divider. The specs on the cam are:
Grind: 262
Lobe Center: 109
(Intake) Cam lift: .290
(Intake) Valve Lift: .465
(Exhaust) Cam Lift: .290
(Exhaust) Valve Lift: .465

I have not been able to get the motor to idle and the motor will only run if I have the gas pedal 3/4s to the floor. When I inspected the carb and intake after operation, I found a large puddle of fuel in the base of the intake. I figure I am flooding due to the cam-shaft (or so I was told). To correct this, I have purchased a Weber Jet kit. The carb has not been modified in any way, so I am running the stock jets. I have a 45 idle jet and 185 air corrector jet. Should I go up a size in just the idle jet. ( I do not think going up in idle jet will help me with this since it is flooding.) Should I go up in the air corrector jet size?
I tried to adjust my float today. I figured that if the motor keeps flooding out, maybe the floats are not set to match my motor. I raised the tab on it a couple of mm and put it all back together. I now can not get the motor to rev beyond 1000 rpm. UGH!!!!
Any suggestions?

I always run a 60-65 idle jet to get the 200s' to idle, the air corrector jet is usually ok. As for float level you might have had the float level too high flooding the carb. Set the float back where you had it, change the idle jet and start from that base line. the key is to not change too much at one time to keep track what adjustments help.

Sounds like a float problem,dirt on the needle valve or a improperly seating needle valve. That's way to much gas for it to be a jet issue. Since I never got any answers to my questions on the Idle Jets in my 32/36 I'm not sure of there size recomendations but increasing the air jet will lean out the mixture in the HIGH RPM range. These work with the MAIN Jets say above 2500 rpm. Not your problem at this point. So your looking more than likely at the idle circuit (under 2500 rpm's) and I can't see anything that says your idle jets are way out of line there.

Steve looking for info on my 32/36
Venturi's are stamped 26 primary and 27 secondary
Main jets P = 132 S= 150
Emulsion tubes P= 16 S= 15
Air corrector Jets P & S= 180
Idle jets ??
