Compression PSI
 

Hello to all in T land
I acquired a 1918 T Roadster awhile back, though it has electric start added and changed to a steel firewall.
It was running pretty rough and I started down the road of troubleshooting.
In the process, I took all the spark plugs out and performed a compression test.

40 PSIG on all four holes.

I'm doing this at 7000' elevation so if you add 25% compensating for altitude, round numbers, it would be 50 PSI at sea level
I am thinking that is in the ballpark of acceptable for a T engine.
Agree or disagree....??

I've got it running well, it's remarkable what rebuilding and timing coils will do in conjunction with a new timer!

Thanks

Your engine seems ok.

I was thinking so,
Thank you for the confirmation

Re: Compression PSI
 

Even at sea level, 40 would be ok.
