I've not read the rest of the thread but noted you were apparently still
Anybody suggested checking the exhaust screen (I'm assuming it has one)
for C deposits? Sounds like it could be clogged w/ buildup which will
cause such symptoms...
I know it doesn't do much good, but I did do a visual check of the
head gasket edges. Nothing unusual, but I'll check it with some sudsy
water today. I lent out my leak down tester (I hope to get back soon)
so I had to use a standard cylinder compression tester. I got
consistent readings of 74 psi with a warm (not hot) engine. I think
this is a good reading since it's a small cylinder, unlike an auto
engine cylinder. Manjo
If you did have a leak at the head gasket; you might hear a slight
whistle sound with the engine running. A blown gasket and I doubt the
engine would run, as the power combustion goes out the passage/leak.
The exhaust has not been checked. I did put my hand near the exhaust
canister and I could feel puffs of air as the engine ran at normal
rpm. But now that you mention this, the air pressure felt a little
low or soft. I'll pull the can and check it today. Manjo
Really, take a good look at it. I had a string trimmer with similar
start/die problems, that I spent weeks on. Rebuilt the fuel pump, etc.
Then I cleaned the 'spark suppressor' screen, and it's run perfectly
I've since been told that running small engines at less than WOT will
load them up with carbon.
