ok.... I have a 8200 HST- and was having problems with it missing on cylinder 1 (closest to the radiator) so I did a compression test and got the following results
cyl 1 = 350 dry 365 wet
cyl 2 = 350 dry 360 wet
cyl 3 = 400 dry 415 wet
after that I did a leak down test and all were good so I took the head off and had the head reworked with new springs/valves etc
after I installed the head back on I am still getting nothing on cylinder #1
I can take the exhaust manifold off (muffler)and it's cold as ice out of that #1 exhaust port
now I can give it some throttle and run it up to about 2200rpm's and #1 will try to fire but will not keep firing
I have triple checked the valve lash and all looks good there
have also checked to make sure there was no air in the line on the injector

any help or ideas would be greatly appreciated as I am scratching my head now

It sure sounds like a fuel delivery problem.You have compression but no fuel to complete the combustion process.Maybe an injector test is next?If the other two cylinders are running OK,it would seem unlikely the pump is faulty.Good Luck!
