3014 vanguard engine won't start

Hello as I am new to this forum.
I have a 3014 vanguard twin 14hp.
Model #294447 Type 1145-A2
After snow blowing with my SB38 snowcaster the other day my GT won't start.
I changed the fuel filter, fuel pump, spark plugs and a new battery
It just back fires through the carburetor now when I try starting it.
Getting good spark.
We did a cold compression check on it and #2 cylinder had 100psi and #1 cylinder had 150psi.
Any help would be awesome!

There is something off big time 100 psi on a Briggs is bad, and 50 psi difference is bad as well. You have a issue with that one cylinder, likely a valve/push rod issue as those are common but so are Briggs head gaskets. We have videos on Briggs head gaskets, valve adjustments and bad head gaskets and many other things. I would pull the valve cover on the bad side its 2 nuts and may give you a answer in 30 seconds. https://www.youtube.com/@caseingersolltractorsnortheast/videos and welcome from Case Ingeroll Tractors Northeast!
Thanks Rockland Valley!!
The repair shop that I took it to today suggested that could be a possibility too!
Thanks much for the feedback!

Pic of horizontal shaft 14/16/18 Vanguard camshaft. On the exhaust valve cam lobes are the compression releases for easier starting. Doing a compression test on these engines produces unreliable results.
Specific positioning of the piston is required when adjusting the valves.

Thanks Bob!
Thanks Bob!
TDC less 1/4" ?? I did watch the video from ROCKLAND VALLEY! Very useful info for when I do my spring and winter tune-ups
Also with all the compression coming back through the carb I should replace the breather assembly right?
Just things I need to know to replace seeing the repair shop will have parts taken off the engine that are not too easy for me to get at.

Thanks, Replaceing the breather if you think you have a issue with the breather or oil in the air filter issue.

Most times we have found the compression tests to be pretty handy and reliable on them, and if we find low or off compression we do a leakdown to confirm or pin point the issue. When the compression test shows off or low they have been accurate as to telling a issue. Yes in theory the compression releases can interfere or really make a difference IF failed. But from our experiences this is very rare but definitely possible. Most Vanguards in good shape we have seen 165 to 185 psi and ones 150 and lower seem to have wear and or issues. Both cylinders should be very close to each other. But this 100 psi here on 1 cylinder, there is something really wrong besides wear. We would do a leakdown test to confirm. But, if the ACR failed then that low comp reading would make sense too. Bob how many failed ACR have you seen over the years? Do you consider it somewhat common or a rare type of deal? Thanks

!!!!!!!UPDATE
Hello again everyone.
I just got an update on what the problem is with my Ingersoll 3014.
The repair shop said it is a bent push rod. The head is also bad because of the engine over heating and I asked him to replace the head instead of a repair.
Not sure why it over heated because I do check the fins and look for other build up of grass clippings, snow, ice, leaves or whatever does not look right on the engine & the whole tractor as well.
He thought maybe that a mouse may have nested somewhere on the engine that may have made this happen prior to me snow blowing with it the last time I used it before it failed.
I forgot to ask him which cylinder it is but I will keep you all updated!
When the repair is completed and I pick up my gt.........(aka...one tough machine) I will post more info on what I know. I sure did miss not having it since the last 20" of snow that we got but my son brought over his snow blower and cleaned up my driveway and sidewalks!
Again, I thank you all for your replies and knowledge of my problem of my 3014 not starting!!
