i shanged all the bearings and it ran fine for 20 minutes then started spitting and shaking and making pfft noises when i hit the gas.like this vrooom pfft vroom pfft pfft vroom offt pfft pfft pfft bang pfft pfft vroom. if that makes sence lolso im thinking its the timing or the engine is not good any more.DO YOU THINK ITS THE TIMING?and can you refresh my memory on tdoing timing?make sure the number 1 cyl is up and the distributor is in the number 1 possition. then make sure its just barely over top dead center and thats about it right?
why did you touch the timeing to put bigends in,if you didnt it wouldnt change by itself
could be timing or something as simple as split in inlet pipe did you use a strobe light?
If all you did was replace the rod bearings then depending on the crankshaft condition if in perfect condition then start at the basic. 1) Remove #1 spark plug 2) Remove the distributor cap 3) Put you finger in the #1 spark plug hole and have someone crank the engine (it can not hurt you) 4) If the timing is correct when you feel the compression the rotor will be pointing at #1 if it is off then remove the dist and reset it, if all is good then check other things as points and vacuum hoses as well as carburetor choke setting. 5) If the engine has old ignition points then check the gap or just replace them and set the dwell correctly and you should be OK, make sure the wiring is correct as well as the cap is not cracked and the rotor is new. Good luck and God bless you.
First mistake: nickel-and-diming engine repairs. You broke the crankcase seal to replace your bearings, now you are chasing a golf ball on a one-hole par 1 course. Your timing marks for crank and cam gear should meet vertically straight depending on the make/model. The rotating assembly is a precision-balanced instrument with extremely close tolerances, if any part is thrown off balance you have compromised its integrity. Second mistake: you didn't state year make or model of car. Not all are created equal.
