I finally got around to pulling it apart and found 3 out of the 4 pistons. We have a Wisconsin VH4D (about 25hp V4) in our mower and she's been blowing heaps of smoke, been using lots of oil and started running better with 3 spark plug leads connected rather then 4. On: 09 July, 2013, 03:45:32 pm. There is a specific method that includes taking into account the mechanical advance, and it's clearly delineated in the manual, which I don't have access to right now, but can soon and would be happy to pass that along.Wisconsin VH4D piston problems. Y-97-1 (With GD-103-1 DRIVE GEAR.Timing is CRITICAL on these.

AND the dist runs backwards compared to Chev small block were most of my experience is, so I fell for that big time. On a 4 cyl, two cylinders are always good and it runs pretty decent BACKWARDS fired, believe it or not. Bad timing makes them run lean and eats pistons.Also, a classic mistake I made on my first was to (despite KNOWING better) get the firing order BACKWARDS. Fits the following Wisconsin 4 cylinder engines with Per-Lux distributor Fits Per-Lux distributor models.The timing marks are on the shroud and one of the cast iron fins on the flywheel is the reference.

(I have like 3 sets of head gaskets.) And watched each individual piston as it rose in comression. Was took both head top off. Mine is the VF4 with elect. The Shroud on mine was damaged pretty bad and i cannot see the marks as described.

Advances itself after so many RPM to not click anymore. And think i understand that the Impulse mag. HOPING i have fixed the problem. The 'Key way' to look into the mag Revealed the X marked tooth through the keyway. As i hand turned the engine slowly i heard the 'Click' exactly as the pistion was at TDC. And when i put it together.

I havent cleaned my carb out this year. New, And the manifolds connecting were re surfaced. And ALL my gaskets are tight.

Im young and didnt know what a Mag was until i got hit by one!Man, sorry so slow to respond. (yes the valves were machined and new) Thanks for you time brotha!Also the plugs all have good spark. And slight pops from the carb.

The timing really won't have anything to do with the 'click' of the impulse. I rebuilt the carb, went nuts checking that throttle shaft, new points, cap, rotor, wires ALL SORTS of stuff because it bothered me, so we'll double check that.Even without the mark on your shroud, I'll do some measuring on a few I've got around so we can get the timing correct. Many of the castings are interchangable between the VE-VH4D models.My number is 4, leave a message or text is fine if I don't answer.Believe it or not, that little popping at lower speeds is about all the evidence I had of having my firing BACKWARDS. There's even a 65hp variant that looks the same, but all the castings are larger. The 'h' is for hardened valve seats by the way), but it should be the same. The manual is for a VH4D (30hp, they came with both mags and points), not sure it covers the VF4 (25hp I think.

That fan/flywheel draws A LOT of air and should be all it needs if the shrouds are in place. Even adhesive backed aluminum tape (REAL duct tape I guess) would be fine and should be durable enough. So not going to say anything definitive until we read that.Insofar as all those metal shrouds, plug the holes however. They do disengage at even idle speeds.I haven't read the section on timing with a mag though because all of the ones I've rebuilt have ignition systems, though I've got a couple to rebuild with mags.

Would probably sieze before damage to them anyway.I'm probably going to set up a few to run aux machines around the mill like planers, gang rips, etc. The big roller bearings on the crank shaft NEVER need replacement unless it gets run without oil for a long long time. Idling is fine, just don't load the motor that way, not enough rpms to pull enough air to cool.These things should run like 3000 hrs between rebuilds, and can generally be rebuilt indefinitely (bore, bore, bore, sleeve. DO NOT 'work' the motor at anything other than full rated rpm (it's like a tractor motor, made to be run full speed on the gov). However, they do have a pretty long break in time (the Bobcat 610 manual says something like 100 hrs!).
