Hello all. This is a very cool site. I just bought a 67 800 with a 152 4 cyl. 3 speed tran. It run but is missing out at lower speeds. A little about what has been done to the Scout. The person that had it before me put an aftermarket fuel pump in it which I will leave alone. I did have to wire a relay into it as well as wire it in. Is there a chance that it could provide too much pressure? It is a very small 12v pump.

What would I need to do a full tune-up?
I am going to replace the plugs and wires. Is there anything I need to do with points or a rotar cap or anything?

Basically, if you were going to do a full tune-up including an oil change what would you need to get?

Thanks,
cody
 
Welcome cody. Yes, your electric fuel pump May need to be regulated. First, you'll have to determine what the current output is with an accurate inline pressure gauge. The stock Holley 1904 requires roughly 5 psi. The stock mechanical pumps were calibrated to delivery in the range of 4.5 to 5.5, and thus do not require additional regulation. If you're running an aftermarket carb such as a weber 32/36, the pressure needs to be even lower.

A full tuneup would consist of new plugs, wires, points, condenser, rotor and distributor cap. Ihc utilized several different distributor models throughout the s80/800 slant 4 production run. Properly identifying your model before purchasing parts will be necessary. Replace only one spark plug wire at a time to avoid a mixup. Purchase a field service manual for your Scout available from ihon at your earliest convenience. Its an indispensable reference for the diyer.

As for lof, its winter, so take your local climate into consideration. I run 20w-50 during the warmer months and 15w-40 in winter time. If you've not done so already, spend some time perusing the various sub-headings in this forum, especially gas engine tech, carb tech, ignition tech, oil tech, and electrical tech as you will find many of your questions May have already been answered. You need to educate yourself about zddp requirements for older engines and the insufficient amount of that formulation in most commercially available motor oils today. IH Parts America sells swepco oil which has this formulation covered.

For oil filters, if you have the large canister filter in place, your choice is pretty limited. If you have the spin on filter adapter, look for brands such as wix, hastings, baldwin, purolater, and even partsmaster. All are good choices. Fram is about the worst possible choice.
 
That is about what I was thinking. I am just north of san antonio texas so we usually don't have to worry about cold for oil. It is not worth chhanging for the week of winter we have. I will do what I can until I can get my hands on a manual.

Thank you for the information. As the Scout is transformed, I will post updates. It will be a long slow process though. I have a 5 month old son we named Scout so I had to get a Scout of course. Who knows, maybe it will be his some day.

Thanks again,
cody
