help

i need help with my next step as you see in the pics its all varnished the sleeve looks okay but I'm no expert

 

[Snook Man]

From that pic, it doesn’t look well to me.

Need better pics (macro) of the top of the piston and the head button.

 

[MaxxJTmasheR]

should i completely tear it down and post more pics? is there any special way to tear down an o.s engine

 

[Jacknifejuv]

the top of that piston and burn room really doesn't look good, has it been sitting for a while

 

[MaxxJTmasheR]

yea it has i tok it fully apart and the entire engine has a layer of varnish, should i just give up or can it be cleaned?

 

[Macguyver]

i would try cleaning it ...with what ? i dont know ....WD40 is good for cleaning ...but you might need something stronger to remove all the varnish ...maybe soaking it in nitro fuel might work to

good luck

well i took it apart and the piston has a small crack on the bottom almost like a chunk missing, i think i need to get a new sleeve and piston, still cheaper than buying a new motor i guess, I'm going to soak it in wd-40 and at least clean it, now there are two bears that the crankshaft sits on should how can i pull them out i tried tapping them out but they will not come out

 

[Macguyver]

to get the bearings out , you have to cook your engine in the oven ..unless you have the right tool for the job
