VH4D Wisconsin Timing Compression

I have a VH4D Wisconsin with a distributor in a skidsteer, It was stuck when I bought it so I took the head off, cleaned up one cylinder and put the head back on, valves are working now, it has compression in all four cylinders but won't run, keeps backfiring, with a distributor what is the firing order, what is considered good compression on these, any tricks to finding top dead center and how are the cylinders numbered. Any other tricks to get this running is appreciated.
 
Hey there, I dont have the manual but first look at your distributor see if there's a number 1 stamped on it,if your dist. has not been removed start watching the dist. when you turn it over slowy watching the rotor button,trace the plug wires if not even though its a 4 cyl. #1will be either left or right front cylinders generally the left I think,you can use your finger to see when you are on the compression stroke through the spark plug hole, theyre will be a whosssh when on compression, see if its firing order is 1,4,3,2 hope this helps, Dw
 
This I found this in a search of the archives.
I don't know what good compression is but they start and run with 90 lbs. of compression.
Any chance your dist. is mounted in the "V" between the cylinders and not down low on the left hand side. Good luck.


Paragraph quoted direct from THE VH4D Repair Manual from Wisconsin Motors not some wanna be Wisconsin site!

" FIRING ORDER"
"The firing order of the cylinders is 1-3-4-2, and the magneto and battery type distributor rotate at one-half engine speed, as is the case with conventional "inline" engines. The intervals between the firing of the cylinders is 180 degrees. No. 1 cylinder is the one nearest to the flywheel in the left bank of cylinders, when viewed from the flywheel end of the engine. No. 3 cylinder is the other cylinder in this bank. No. 2 cylinder is the one nearest to the flywheel in the right bank of cylinders and No. 4 is the other cylinder in this bank. The cylinders are numbered from 1 to 4 on the air shroud near the spark plugs. The flywheel end of the engine is designated the front and the power take-off end, the rear of engine."
