I have a 14.5hp Briggs&Stratton engine that came off of a yard machines tractor and was running fine but got tipped upside down and had oil run out of the carb. So i pulled the head cleaned it out replaced the head gasket and got fresh gas then cleaned the carb with compressed air. I attempted to start it today and it started but would only run if i quickly worked the choke. I think that there must be some type of blockage in the carbuerator and i think cleaning it out might help but if anyone has any ideas i would enjoy hearing I really want to get this engine running again. I bought a compression gauge and it has about 65lbs. of compression but i dont know if this is enought or not when it does run it sounds good but i cant adjust the needle valve due to it having a plastic cap on it thanks for anything that will help

Hi & welcome to TSF.

65lbs is fine for compression

Most likely problem is that the oil has found its way into the carb jets & ports - should be a simple clean out job - but you may need to remove the carb and bath it in carb cleaner (or fuel) and rise and thoroughly blow out all the fuel passages and jets

No problems Whitewolf - pleased to help -

Let us know how you get on and don't forget to give the poor old carb a good blow thru with compressed air once you have rid it of old sump oil.

Also - as the combustion chambers are likely to have been filled with oil don't forget to give the plugs a "good bath / wash" as well
