Leak down tester is great. Sorry one more question. Is this a Vanguard or Intek V-Twin engine? Will make it easier for me to give instructions. Thanks.

It's a 25hp v twin I know you have helped me before but when we get this done I am gonna send you the whole story of everything I've been through with this mower, think this is the 5th problem I've posted, every time I think it's finally done then it's something else but I'm determined to get it right

It should say Vanguard or Intek on the engine.

Just got done with compression test I got 80 on the left and 60 on the right, guess he didn't have a leak down tester but the compression was holding until we released it. I checked the vent hose to the air cleaner it was clean and when it's running I can feel a small suction coming from it, let me know what you think, thanks again

The breather tube should have some suction, normal. I really don't like either of your compression test readings. You should be getting close to if not over 100 psi on each side. When you took the readings did you have the spark plug in the other side? Did you make sure that you cycled it through at least 4 compression strokes? Was your battery fully charged? If you say no to any of these I would you to do the tests over. You will have false readings other wise and we may come to bad conclusions. Also, were you able to download a manual from the site I gave you or should I look for a different one?

I had a fully charged battery I did at least 6-8 compression strokes, I did have both plugs out but I just when out to the garage and with the other plug in I got the same results, I had no problem downloading the manuals. Do you think I should just do both head gaskets or could it be something else

Let's just do the right side first, and we'll decide after you tell me how it looks. If you really want to do this pull the right side head following the instructions in the manual. Make sure that you label the push rod so you know which is which. Do not remove the valves from the head. Do you realize that I may be asking you to recondition or replace the valves after you tell me what they look like?
