Hey guys. i was wondering if anyone knows what the cylinder compression should be on the ht1400. i think i might have a blown head gasket so i'm doing a compression test to see. so far i've done the front four cylinders and the results don't seem too promissing. i got between 150 and 190 kPa across the cylinders i've done but i thought that seemed like a pretty wide range, yet it doesn't seem like enough to be a head gasket. but i don't really know so any help here is greatly appreciated. thanks a lot!

oops thats in psi not kPa.

Compression test is not conclusive. Get each cylinder to TDC and use shop air to pressurize the cylinder to 120 psi and let it set for 20-30 min. see if it holds pressure.
