The 16 hp Briggs for the Allis project

[Rustyoldjunk]

Finally took a little time to get back to this.
I put this 32 c.i. cast iron 16hp Briggs into a project 710 3 speed/912 hydro hybrid Allis tractor that I put together.
The engine appeared to have been freshly went thru but when I put it in the tractor it didn't want to start and when it fired it kicked back so hard that that it was immediately stripping the starter bendix.
So I pulled it back out and started trouble shooting.
It's a factory pointless engine so I first checked to be sure it had the correct coil and flywheel.
Then checked for a sheared crank/flywheel key.
All looked good.
But...the mag was touching the flywheel,improper gap.
Next I checked the valves and they were way to tight.
So i cleaned the mag and flywheel contacts and gapped the mag.
Today I finally got back to it.
I pulled the valves and filed the stems to adjust them.
The gap for the intake side is suppose to be .007-.009.
I had to file .008 to get a proper intake clearance.
The exhaust clearance should be .017-.019,I filed down .004 to get the clearance that I needed there,the exhaust wasnt as far off. Both valves look new. Looks like somebody went thru the engine but didn't finish the tuning.
I got the valve cover,carb,exhaust,and head back on tonight.
If I have time tomorrow I'm going to swap the starter bendix and test fire it in the shop. Hopefully the issues are resolved.

Reception trouble here at home. Gotta love / hate the digital age.
Let's try loading the pictures one more time tonight.
I loaded these pictures on the first post in the thread and and it wouldn't load the tractor picture that's on the first post so I cancelled that picture and hit submit....then that's the only picture that came up with the post lol.

Did it look like the valve seats were cut and the valves lapped in ? Everything else look good ?

I hid the other thread for a bit! Hope you have it fixed.

Thanks Kenny...again.
How many years have you been taking care of my forum issues now ?

I don't know, don't keep track of that stuff. I just fix what needs it.

I took a little time a couple of days ago and put the starter on the engine to to fire it,but first noticed this issue as seen in the pictures. The starter head plate is swallowed out pretty bad where the bendix shaft comes thru it. I either need to bore it and bush it or find another head plate.
I went ahead anyway and put it on to test fire the engine.
Still had major kickback.
So I pulled the flywheel nut again and took a better look.
The flywheel IS sheared.
Found the right puller and got ready to pull the flywheel.
Aaaannd...don't have the correct length puller bolts.
So sometime,hopefully in the next few days,I will get to a hardware store and get the bolts that I need.
