I presently have a Toro ZX4800 which is now 13 years old. I have always had an issue with the right hand drive, replaced after 2 years, rebuilt after another 4 years. I have used various recommended oils although the last 2 changes (do every year about 200 hours) was with the Triax. It is...
I have 2 ZT2800 drives with 20W50 Trax synthetic in them. My right drive stopped running normally and I removed and disassembled. All the parts have a sticky texture on them and the pistons in the pump assemblies some of which were stuck in the down position. Cleaning the pistons and holes...
Ha! I'm not computing either, matter of fact royally confused and frustrated. I have been told by several people that WD40 leaves a sticky residue. I do not know!. I DO KNOW it tried to start with ether, then gas but backfired both times so at that time I must have had compression of some...
When the valves are closed on #1 she is close to TDC as best as I can tell. I should have removed the gauge and stuck a wire down the spark hole to see if the piston was up, was not thinking at the time.
I thought maybe something wrong with the compression gauge but holding my finger over the holes feels nothing. It spins over like there are no spark plugs in it.
Actually it tried to start the first time I turned it over but the dizzy was 30 advanced. It backfired and then nothing. Checked compression and was zero on 1, 2. and 3 before my hands froze.
According to a backyard mechanic here that buys a lot of Ford Motors from the junk yard he sees this all the time. Usually though the piston itself is stuck. But he claims the carbon buildup I saw on the top of the pistons is also on the rings and it hardened, especially sitting open for a...
Frankly I wondered about the WD40 myself but nobody made issue of it I spoke to. Have any idea the procedure for using the Chemtool?
Thanks for responding.
I just completed a head gasket change on a Ford 400 engine. I noticed the tops of the pistons were well carboned up when the heads were off. The engine sat for close to 2 months open BUT I did spray the walls down with wd40. After finishing I attempted to start and found I have no compression...
