I got a 1977 Kitty kat for a dirt cheap price. The guy said it had not be ran in years, and i figured the worse that could be wrong with it was the carb was dirty. I check compression it is 120psi. Checked spark, looks great, nice and blue. Cleaned the carb put it back together and it wont fire. I can run gas in the cylinder and it will fire, pour some down the carb and it will fire, but nothing just having the choke on and turning it over. The peck #### on the fuel tank is loose, so i took some permatex and tried to seal it the best i could, to prevent air from getting in there. I havent put it back on yet to see if that made a difference or not. But if anyone else has any suggestions to what the problem could be, and/or how to fix it i would greatly appreciate any help. I have a 3 year old that is itchin to ride!
