What Gord said. Take it out to a field, and put it to work for a half hour or maybe a full hour. Park it, and then start it from cold after it sits for a couple hours or overnight. You may find it has stopped being a juvenile delinquent and has given up smoking completely. If it had...

White smoke is generally NOT caused by oil being burned inside the combustion chamber. You may want to re-think replacing the cylinder head as the cause is likely NOT loose valve seals or guides. tom

Certainly you can try to run the pump on 120vac. There should be a diagram indicating how to wire power when set to the 120vac setting. Likely you will have line & load & a ground. Connect that way, switch the selector to 120vac and it should work. It could be there is a fault in the motor...

Note: I did NOT check any source for availabiltiy, nor did I do ANY price shopping. That is beyond my level of interest & knowledge. tom

You have what is known as a 'flat head' engine per the diagram at partstree.com. As the valves wear, the tip of the valve will get closer to the tappet which opens the valve when the cam lobe pushes on it. There must be clearance between tappet and the valve stem or the valve will not close...

Symptoms point to valve stem seal leakage, or worn valve guides. Mostly intake valve stem seals will allow oil into the intake when vacuum is high, or given time for oil to seep down the guide around the stem. If you did not replace the valve stem seals, it would be a decent bet that doing so...

Dreaded, the time I had the problem with the Kohler, after the leak was cured, the fuel consumption went from over 1 tank to do the front yard only, to about 1 tank to do front and back yards. Significant reduction in fuel consumption doing the same amount of mowing. The only thing changed was...

I think the numbers are stamped into the case. If you look up from behind the seat area, on the rearmost surface, you will find the model number. You may have to scrub a bit to see them. tom

Briggs & Stratton is in bankruptcy(was a few months ago), and Craftsman has been split into multiple brand 'channels', and is retailed by a few stores. Likely both produce overseas rather than within the USA as was done previously. Most people that buy at the low end have little interest in...

I would be checking the float height. To do so involves removing the carb and the float bowl. Then flip it upside down and view across the float and the lower edge of the carb body. Generally the float body should be parallel to the edge where the float bowl gasket seals. If the float...

If you have them local, Tractor Supply(menards?) sells 'tractor paint' in gallon size cans. Perhaps in quarts too, but either way the cost per oz is relatively low compared to body shop paint and the 'rattle can' paint. Check IH red to see how close it is... tom

I have had fuel lines that looked perfect fail to flow reasonably. The fuel over time had destroyed at least partially the inner surface and turned it into a maze. Fuel would not flow freely(gravity) through the line. You could check for gravity flow from the tank to the pump/filter, and then...

The fuel outlet inside the tank is getting clogged as the fuel falls into the tube leading to the fuel line. You may be able to remove the outlet(or not, depending on design) and clean up the schmuz, or will have to see if you can flush it out after removing the tank so you can position it to...

If is has a clogged fuel line, preventing the flow of fuel for starting at LOW rpms... how does a clogged fuel line feed the engine when it is running at HIGH rpms? The fuel demand increases with engine rpm, and cranking is low rpm, and thus low demand. If you have a shutoff valve, that may...

I have had good luck with JacksSmallengines and also with psep.biz. Pats small engine parts. Both have treated me fairly, and for the most part, if they advertise the part, they have it. Some sites still list parts that everyone else lists as NLA, get you to order, then futz around to reverse...

Did the new cam have the movable part that is spring loaded? That is the compression release that bumps the tappet/lifter when the rpms are low, and then swings out to stop bumping when rpms increase. It must be movable and also must return to rest when the engine comes to a stop. They are...
