So this is my first post I have a fully rebuilt Viking and it’s been good for a little while now i had to replace the cylinder rings and I took the timing chain off I messed up the first time did the timing wrong and broke the chain new chain right timing all works but since then i have been having issues when I go to start it it just barely turns over surges dies then finally starts 50 precent of the time I ran down all the usual new relay new Chinese starter and fresh battery but it just sounds like it’s struggling to turn over the motor. Any advice.
