I am almost ready to test my engine but have a few questions. Where do you fill the oil from? Also I assume the oil pump needs to be primed so what is best orientation of motor when filling and where to fill (oil gallery?) Or can I flip engine upside down and fill from oil drain pipe...

I'm taking a little break from the Howell V4 engine and finishing up an engine I started but never finished, the LTD Miser engine. My question is regarding the clear displacer ring. I ordered a piece from the howell website and the inside is not round. Measuring the ID in a few different...

You should try starting a new thread asking instead of posting in this one.

So If I under stand correctly, the cap wires are like this: Is the magnet disk like this: or this:

Posted in my "How to set up a Distributor thread", but maybe all you Howell V4 builders will see this and be able to help me out. I Need some help understanding something... In the V4 plans, on sheet #63 it shows this: The rotor viewed from top rotates clockwise. I rotated engine CCW from...

Need some help understanding something... In the V4 plans, on sheet #63 it shows this: The rotor viewed from top rotates clockwise. I rotated engine CCW from flywheel end of engine and the magnet disk rotates clockwise just like plans say. It also says firing order is 1-4-3-2. If the...

I got a PICTIM ignition Module from Howell, it says that its programable, but I can't find how to do it or what I need to do it for. Does a ignition module that's programable take the place of having the linkage connecting throttle body do distributor?

Currently working on assembling the throttle body, and the way it is right now, the lever arm for throttle moves to the right (CCW) when going from idle to full throttle, so it would pull the distributor lever arm in the same direction (to the right). This next pic is top view of...

Does that mean I have to get a left handed tap?

For the throttle linkage, the holes in the throttle arm are .035 and the ones in the distributor spark advance arm are .050 I was thinking of threading one side of both the end pieces 2-56, then turning ends to .035 and .050 and bending them. Then use some hex stock to make the green pieces and...

If I understand you correctly, To set #1 10 deg BTDC like you said I attach the degree wheel and use it to move 10degrees BTDC. To test when the Hall Sensor is being triggered I send 5v to pin 1 , ground to pin 2, and put multimeter leads on pin 2 and 3 I rotate magnet disk so that I...

Before I spin the crank around to set the valve clearance, I think I should install the distributor cap while the #1 piston is at TDC (I know my cylinder numbers are labeled wrong, but I had other parts/pics referenced to it before I realized it, so kept it to avoid confusion) My question is...

This is a v4 engine by Jerry Howell. model-engine-plans.com

oh yeah I forgot the lifter needed to be down not up and find the lowest point of lifter

This may be a dumb question but I just wanted to verify the procedure on how to set valve clearance. The Howell v4 plans says to set it to .002. To set the clearance, do I hold engine like this and find the highest point a lifter is, then use feeler gauges to set the .002 clearance? Then rotate...

I reamed the holes in the head 13/32 (.40625) and made the valve cages .406 like the plans say. I recall just putting green loctite in the two grooves ( and maybe a little bit between them) I put the head on a flat surface and pushed valve cages so it would be flush with the bottom of the...

I made the part that the cap will have a screw in by putting some round brass stock in a collet block, milling the contour, then transferring lathe to cut it off I wanted a way to hold it so could align it with the cap for soldering. I tried with piece of brass with v notch on left of pic, but...

The reason I am going to lightly lap is to get a better surface finish and thus perhaps a better seal. It seals right now, but not as much as I think it should

I made the valves first, then without moving lathe compound, turned the seat cutter so the angles will match

I used valve seat cutter and made a very small seat, haven't lapped them yet. The plan is to lap with the highest grit lapping compound I got, put in ultrasonic cleaner, then test with pressure using thing I made.
