Starting a long idle machine?

I should be able to get the Cockshutt fired up later this week when the coil and wires arrive.

Any thing else I should be careful on? , it hasnt run in 10 years or so.

I have turned it over by hand and added a couple squirts of oil to each cylinder. Every thing seems smooth and there is pressure in each cylinder.

Good Luck with it.I here those Hercules engine parts are very pricey, if you can get them.

In addition to the advice offered below, make sure the governor to carb throttle shaft linkage operates freely.

If it's not, find and fix the cause before attempting the first start - ESPECIALLY if the linkage is stuck in the wide open position!

An uncle failed to do check this while trying to bring back to life a long-dormant 1750. On the first start attempt the engine took off and put a rod through the side of the block on account the carb throttle plate being stuck wide open.

I would also crank it over with the plugs out till I got oil pressure on the gauge.

My self I would fill the cylinders with tranny fluid. I do that to all the tractors I get and 99% of them don't run and haven't run in years so thats why the ATF in the cylinders. What the ATF does if frees up the rings and also prelubes the cylinders and valves. I would also run some gas through the carb and out the drain plug to make sure you have a good flow of gas and not all clogged up

I havent owned any Cockshutt or Co Op for a few years buttttt ttt if it hasnt ran for 10 years Id reallyyyyy yy be surprised if the carbs needle valve n seat and float assembly isnt all gummed up among other things. Id drain all the gas n clean n flush the tank n any sediment bowl assembly and at least insure clean fresh water free gas is entering the carb and is filling the bowl which I'd also let fill n flush n fill n flush to try n clean n free up the needle valve n seat (if its gummed up) and insure the float is okay and rises to shut the gas off in the carbs bowl at the correct level. Id also remove n check n clean any air cleaner bowl assembly and inlet air piping etc to insure good air flow.

Of course, drain n flush n replace fluids and shes obviously gotta have a good hot spark at all the plugs, then oil up the cylinders as you said n Id let her crank a good while with ignition off just to oil things up.

Other things to worry about are stuck valves, but if the valve cover were removed and you turn her slowly by hand if theres problems you will know it..... ....if she has good compression as you claim, they must all be working however

If you suspect theres excess gum n sludge n carbon n maybe the rings are siezed up but theres nuttin nor any valves stuck, Id be tempted to use a good detergent 10 W 30 oil at first with a can of Rislone added and maybe even a quart of auto tranny fluid to give her (esp the valve train) a good clean n flush and then change to just good regular oil buttttt ttttt ttt if you clean up too much sludge she could become a leaker grrrrr rr

Good luck, let us know
