I got a little time today to tinker ....and lo and behold got the 446 running. After looking at some manuals and finally finding the points I set about figuring out what was wrong.
The motor turned over good after charging the batt for a hour or two,, but wasn`t getting any spark at the plugs. I had to pull the air cleaner set up off to get to the cover over the points and condenser. I was impressed with the trouble they went to make sure the cleaner wouldn`t ever come off. 4 allen head bolts to the carb, 2 brackets with bolts, lock washers and nuts. and big air intake hose that must go to a box somewhere I haven`t found yet ...and the crankcase breather tube all fit very well into the filter housing.
The cover over the point`/condenser was mounted to plate that the points/condenser are mounted onto....and was bolted to the block with 1/4 inch allen head bolts. A little rod went thru the plate into the block and rides on ???something rotating in the block I guess to time the points The little rubber seal type thing in the points bracket kept it from falling out ....I didn`t notice it till I got ready to put it back together..
I couldn`t get in close enough to see what was going on with the points but test lite told me I had fire to one side of the points but not the other side when cranked. I took the whole thing out and cleaned up the points. Made quick trip to my local shop to see if I could get any of the points, condenser or coil before they closed at noon. Said they`d never seen a Case and didn`t have any of the parts.
So I cleaned up the points, put it all back together...got a little spark at the points now.... closed the choke and went to crankin`!! Took a little bit of crankin to get some gas flowing and dang`ed if it didn`t start right up. Sat there and idled purty as you please....let her warm up a bit while I was try to figure out which lever would make it move.
Backed her out of the trailer and rode around a bit and decided to engage the PTO and see if would spin the blades. Sure enough they spun and we tried a little mowing. seem to work good.....and then it ran out of gas. I did some more mowing and then it just quit....didn`t ant to start till I pulled throttle all the way back and then it finally did....mowed a little more at hi throttle and it did it again. Same solution to get it started again.
Decided to put it in the garage . I was only wanting to see what worked and what didn`t before changing the oil and stuff any way. You can tell by the smell that it is running really rich....really rich and that maybe makin` it run hotter than it should too.
Anyway ...it runs and needs some adjustment ...the deck isn`t hooked up right to the lift for some reason. Overall I`m pretty pleased with my winning bid and can now look at the 444 Demonstrator and see how it goes when I get a key switch for it !!
