Excessive smoke It actually a 1981 H-D Wideglide which I couldn't find in the list. -- I replaced all the gaskets except the bottom end, and rebuilt the oil pump. now it smokes from both cylinders and when i pulled out of the drive, it left a stream of oil on the pavement, i believe the oil came out of the breather tube.Can the oil be backing up in the engine ? i have 25 lbs of pressure and the oil is flowing back into the tank, but is it flowing fast enough ?

Maybe blown head gasket.

first of all u need to determine what color of smoke it is and is it coming out of the exhaust pipe. black smoke means excessive gas burning ...blue smoke means burning oil ...white smoke if seen in warm weather conditions means coolant leak into cylinder heads... but as running rich and high low idle might have a vacuum leak or carburetor need new base gasket or rebuilt ... good luck

Blue smoke is oil burning, white steam/smoke is coolant burning, it will be a sweet smell.
You have a choice, repair the head gasket (if there is coolant in the oil, the bottom end needs rebuilt also) which is around,$300-$1000 depends if a garage or you do it, the problem with doing a head gasket is there is no garantee, if you replace the engine with a used engine you have a 90 day/ 1 year warantee, your choice. about the same cost.

what color is the smoke??

Guide to smoke color
are few exceptions here but for most part

Blue smoke -burning oil- bad rings or bad valve guides

White smoke a little is normal after start up (condensation in exhaust pipes) large amounts - blown head gaskets

Black Smoke - running excessively rich

If it is actually leaking from the bottom there is nothing you can do except replace it, there are no user servicable parts in the bottom end on disposal. I would carefully check around drain outlet and gasket where it mounts on bottom of sink. If it's leaking around drain outlet from disposal there is a replaceable gasket there or on underside of sink where disposal mounts. If you find that it is leaking from either of these locations I would be happy to instruct you on how to change them Hope this helps you, Thanks.

If the smoke comes at start up then after a while goes away it is your heads -take them off and have them looked at in a machine shop If the smoke comes from a load on the engine then the piston rings are going bad -time for a bottom end rebuilt

sound like you have a leaking head gasket , or possible oil rings on the pistons are worn, if you have the head gaskets replaced check the clearance for the oil rings , mechanical shop can do this , just let them know to check them , but i would start with replacing head gaskets , if the smoke it white then you are leaking coolant into the cylinders , either way the head gaskets will fix

hi
sounds like you have a small fracture in the casing (cover)
i would start at the basics and replace the casing (cover)
but whatever you do do not overheat that engine
with that engine the barrels are part of the engine
and cannot be replaced
and if you overheat that engine
the engine warps rather than warps the alloy heads

failing that failing the replacement of the casing
the bolt hole that the bolt goes into
at one time may have had a longer bolt in there
and has gone through the bottom of the hole
there is a product called chemical metal
take the casing off clean all surfaces
mix up the chemical metal and fill the bolt hole up
you will now need to re-drill the hole and tap a thread into it
rub down any excess chemical metal
and make the surface flat again
new seal (gasket)
use some harmalar (instant seal) if need be

mcdevito75 here, Something wrong with--in the carb. Have it rebuilt or replaced. ----- Not unless the gas is leaking from outside the carb. in which case tighten the screws holding the 2 halves of the carb. together.

A faulty door gasket will definitely cause excessive condensate and running time. There is also a door heating system which is from heated refrigerant circulating around the area where door gasket meets cabinet. You should be able to feel a certain amount of warmth in this area. If not there could be condensation again from cold leaking out of the gasket and being formed on the actual cabinet.
