- Just did our first compression test on our 100M engine (all we've done is drive it up and down the little county road in front of my folks's house--20miles maybe). Engine warm, all plugs out, throttl

- I thought you did a compression test with the throttle wide open. Or am I wrong as usual? Bill '53 BN1 '61 BT7 -- When I was younger, I could remember anything whether it had happened or not. But now

- Bob, when I rebuilt my 100 engine to M spec I got almost exactly the same numbers (mid 160s to low 170s) when I did the first compression test, I thought it was a little high as well, but maybe it is

- Throttles should be wide open to get a proper reading. Kees Oudesluijs NL [demime 1.01d removed an attachment of type text/x-vcard which had a name of coudesluijs.vcf] _______________________________

- This is probably a stupid question and obvious to everyone but me, but what is the correct procedure for doing a compression test? Thanks in advance, Elton -- Original Message -- From: "Mr. Bill" <bn

- Fully warmed up engine, petrol pump disconnected or blocked, plugs out, trottle(s) wide open, spinning the engine (appr. 5 seconds) untill you get max. reading on compression gauge. As simple as that

- True, but still hard to ignite the fuel in the cylinders with the plugs removed. But not impossible, I suppose. Gary You are probably correct saying it may not strictly be necessary to shut own petro
