I understand that if you lube everything you don't need to have oil everywhere that is why I wandered in the first place why you need to prime. But now because I tried to prime the engine and no oil is coming up to the heads that make me nerves. What if something else is wrong and I run the motor and no oil ever gets to all the motor. It wouldn't take long to ruin it. Also my motor had the canister type of filter and I removed it an put in an adapter so I could use the screw on type of filter. I am wondering if I could have put it in wrong.
