trace the 2 gas lines back to the gas tank. the fuel line with the filter in the gas tank goes to the bottom- lower inlet of the carb. pull the spark plug. put the cap on it- ground out the plug in the area it threads into. in a shaded area, turn on the radio- pull the starter cord- look for spark on the plug. even if you have to hold the plug- its a weak spark- not like some g.m hei ignition- its not gonna knock you across the room-- as for the bolts- just tighten in a X pattern, little bit here- go to next bolt- little bit at a time on each one. once the gearbox is seated- just approx 1/8 turn more on each bolt.-- on the new carb-- if the gas lines are correct, and the carb is in correct working order- you can push the bulb forever and it will not add a drop of gas into the engine. The bulb simply purges the air out of the carb body. It should actually be called a purge bulb, not a primer bulb-- but thats just my way of thinking i suppose. best of luck to you.
