Thanks Guys,

 will try this, I hope I can get it cleaned up some without changing the cam.

canadian nascar:
Hey Cliff,

Just wondering if the comp 262 cam isn't a good choice what would be a better choice, I have had references to a comp 252 cam but the LSA is still 110.

do you have any preferences?

thanks Kevin

Cliff Ruggles:
I am NOT a fan of any of those short seat timing tight LSA camshafts.  You'd be WAY better off with a Summit 2800 cam, gentle ramps, easy on the valvetrain, and wide LSA......Cliff

canadian nascar:
hey Guys,

car is out and looking at the carb the right side " nozzle " i think it is called is dripping fuel, the little tips inside the circle casting primary side. but the left side isn't, touch the throttle and both side squirt.
the fuel screws are out 2.5 each,
the a/f is 16-1
float height is 5/16
110 gph holley pump 6.5-8 psi
idle 900 rpm a little rough

later Kevin

Cliff Ruggles:
I would back the idle mixtures screws out some.  Those later carbs have very fine metric threads and very small holes under the mixture screws.  We usually have to back them out 4-6 turns or so to get enough fuel to those engines at idle speed...Cliff
