Thanks Terry!!! I am going to redo this engine slowly and a step at a time. So I will need occasional tech assistance and/or parts references.

Here is as far as I got tonight. By the way-the PB Blaster seems to have worked-the recoil is retracting nicely now!!! Soon the flywheel will come off-then the ignition will be addressed. Then a cleaning while it's apart. I have a gas tank on the way. Then the carb......Etc.Etc.Etc. Thanks again-I guess I'll need a Panther Service Manual too.

Like to thank everyone for this thread, being new to Clinton engines this thread is very interesting.

On the ignition modules can anyone list who makes them, whats the part number, and who sells them ?

Is there a right hand and left hand module ?

Glad you are showing some interest-I am planning this restoration step by step and I'll keep everyone posted. Of course, I will have to refer to some on this forum for assistance from time to time......

Modules will work on left or right hand Clinton engines. No changes are required, as long as you have the correct flywheel.

Here is one source for modules. Free shipping.

For go kart use, you might want to replace that heavy cast iron flywheel. Here is a direct replacement:

I see the ad for a new flywheel-is this aluminum? Why would it need replaced for go kart use?

The heavier flywheel will keep you from beating me at TBO!
It just keeps the engine from revving up and down quickly.
Not a big deal if you just want to putt around.

How high can a Clinton A400 rev? It doesn't make that much power anyway-so every rev matters.....

The last model of these engines were rated 2.75 hp at 3600 RPM.
I have seen 6000 RPM on some of mine with open exhaust, Go Power style manifold and a small Tillotson carb.
I always use the improved connecting rod introduced on the 500 series engines. Part number 245-110-500.
The early rods were the weak point for engines used on go karts.

There are a few expensive after-market exhaust solutions, but I just use standard Clinton parts.
This picture shows a 'quiet' muffler and a short exhaust header.
For racing, I usually drill a few large holes in the end of the short header.
Either one can be occasionally be found on ebay for about $30.00

My favorite Tillotson is the HL189. No longer made, but not too hard to find.
A little smaller, but available new, is the HL166.
