[eagle5473 0]

Hey guys havge any of you had this problem. I rebuild the CCKB and got the engine running again...the following weekend it would not start....I got it to run by pouring a little gas into one of the cylinders and it would start and run fine there after, and would start again as long as the engine was warm.... Yesterday I changed out the old fuel pump for a NAPA electric one, and had to dump gas again into the cylinder....Ran like a champ my power loss problems have seems to be corrected.....I stopped and started her 4-5 times yesterday, and started he just before I went to bed, engine was warm too the touch....I went out this am and it would not start...........Yesterday I also pulled the carb checked the float and cleaned off the float valve........I dont know why it wont start on its own any ideas?

Bad carb base gasket and or intake manifold to block gasket.

Is the choke linkage pulling the choke completely closed? Sounds to me as if it's not closeing the choke but about half way.

I had this problem on an engine and it turn out to be the intake gasket. I would check all the gaskets between the carb and the cylinder.

Thanks, The choke seems to be working I will double check it, both main gaskets on the intake/exhaust are new with the rebuild, I will pull the carb from the intake and replace that one and see what happens

Well last night I went back out and double checked the Choke, it needed just a wee bit more pull she started right up.....Sometimes it is the easyest thing that trips you up....thanks for all the help and Dave I used your info to add the fuel pump thanks again for all your help
