Wow,
Looks like you could impale yourself on that drive lever

Guess the guy didn't have a grinder

This morning I took the filter base off the carb, disconnected the fuel line and cranked it over about 10 seconds. I never got a drop of gas from the fuel pump. I got an old tank and put it above the carb and cranked the engine, it ran about 30 seconds before a small amount of gas started coming from the fuel pump line. I let the engine run a while and eventually got a Folgers can full of gas. I engine wanted to run on a little choke and would sputter if I pushed it all the way off. There were only 3 of 4 bolts holding the filter base on and there is a hose connector on the back of the carb with nothing on it. I thought it might be a problem with the fuel line or filter so I filled a Seafoam bottle with gas and put a short line into it from the pump, I crank it a few times like that but never got anything. Are these Mikuni pumps rebuildable? Anything else I need to try before I assume the pump is bad?
I removed the deck. One of the reasons I bought this mower was that it has the same deck as my 1863 and it the best cutting deck I own. Someone had put a 1/2 wide PTO belt on it that I'm pretty sure is wrong. The under side was packed with grass and 2 of the 4 belt guard screws were missing but it wasn't rusted through anywhere. The spindles turn free and don't seem to have any bearing slop.
I assume there should be a guard over the bindix, and that the 14 mm socket wedged on the lower starter bolt is not OE.
I checked the voltage at the battery with the engine running and only got a little over 12 so I need to check the voltage regulator.

Put a 1/2 wide belt on the deck itself? If so, that is correct. I've had the 48" and two 54" decks and all three have had the 1/2 belt on the deck. I also referenced the Cub part # to find out if that's what they still put on them and it is. 1/2 is correct sir

It's the PTO belt. Your right that the deck uses a 1/2. Sorry if the rambling post made that unclear. Thanks

As a last resort on the fuel pump I decided to check the line from the valve cover to the pump. I couldn't find any cracks but it was hard as a rock. I put a new piece on it and tried the Seafoam bottle/short hose and it fired right up and ran. After a while I cut it off and reattached the line from the tank and it cranked and ran alright. Maybe I'm back to where I was when I bought it. before I put the air filter base back on do I need to do anything about the missing hose on back of the carb?

Pretty sure your talking about the bowl vent as labeled in this pic. I just put a piece of hose on them the help keep dirt from getting into the carb.

Cannon51 · #17 12-12-2014, 06:21 PM

Yes, that's the one. Thanks

I removed the nose this morning. As usual I found more damage. I am playing with Picusa trying to figure out how to add text. It's going to take a lot of glue and filler to fix this.

Not worth trying to fix that one.

I was afraid of that. I have a lot more discovery to do on this tractor but I may go the Blackjack or Cadplans route.
I was never able to make the Picusa edited photos show in the post so I put the original ones from windows in.
