    Tecumseh HS40 Oil Dip Stick?

    Hello! I was wondering what Tecumseh oil dip sticks would work in a 1974 HS40 model. The parts diagram for my engine has a dipstick depicted, but no part number available for it. On the engine I have, both sides of the sump cover just have the removable plugs on them to pour oil in, like when...

It has a cast iron elbow and paper element that some of the cast iron industrial "X/L series" Tecumsehs' came with. This means that the crankcase...

    Crankcase cover swap?

    I just picked up a 5hp B&S flathead cart engine from a friend but I need the crankcase cover with the 4 holes for my clutch brake. Are all the 5hp covers the same? I'm mechanically inclined but have never change one, is it as easy as pop to old one off, replace the gasket and put the new one on...

    Hemi Predator Crankcase Bolts

    Just picked up a Hemi Predator and am trying to bolt a torque converter to it. The bolts included with the TC (8mm x 1.25 x25mm) go into the crankcase half turn and then stop. What size should the bolts be?

    Torque converter erratic.

    Crankcase side bearings

    I've been looking for a crankcase side cover with the tapped holes for a 1972 5hp. I see them listed as large or small bearings for the crank. So is the difference just the bearing or is the crank also different? Thanks, Nate

    Crankcase ventilation?

    I have a Tecumseh motorsports h50. Is it necessary to run a catch can or crankcase breather. On most of the drag style mini bikes I see they run a catch can. Why is this and do I need one?

    Tecumseh small frame crankcase mix

    Has anyone had any experience mixing an engine block and crankcase cover from different engines with any success? There seem to be many engine blocks such as HS50 and HSSK50 blocks for sale on ebay without the crankcase cover, but logic tells me that the crank bearings would be align bored...

    Rebushing a 130000 Crankcase Cover

    Hi, I was wondering if there is anyone on the board who would be willing to rebush a crankcase cover for a Briggs 130000 series 5hp engine. I bought this off of Ebay and of course the bushing is shot. I need this cover as it has the four threaded holes for a clutch cover. I don't have the...

    Briggs crankcase gasket. Which one do I use?

    I need a crankcase gasket for my briggs but I am not sure which one I need since there seems to be similar style gaskets with different part numbers. I am not sure if the model number is correct due the possibility of the pull start/shourd being replaced so.... These part numbers all look...

    Honda crankcase venting question

    So if I plan on running 2 vents from my case up to the valve cover, and then 1 off the cover to a catch can.... Do I need to do away with the little deal inside the valve cover? Im assuming some type of PCV valve? Is there another cover that is a bolt on swap without it? Planned on just...

    Crankcase breather via the header?

    I just made a header that has a bung that allows the valve cover breather hose to be connected to the header to allow those gasses to exit through the header. I've seen this done on cars, and done on a 5hp Briggs once upon a time. My question is, would I be able to use a normal black fuel...
